Olight Protected 18650B 3400mAh Battery Thorough Review And Test This Battery Delivers
Last update 01/07/19
When I do load tests like this I set my load tester to bring the battery to it's lowest safe voltage in the battery manufacturers spec sheet. If it is a protected cell it doesn't matter how low you set it the protection circuit will cut it off before it damages the battery. By drawing the battery to it's protection cut off you will get a more accurate account of what the battery is capable of. If your device you are using it in stops working at say 3 volts then that is a good place to set it as you will be able to determine how well that battery will perform in that device. I am usually trying to determine total WH and MAH in order to make sure the cell is performing up to spec when new.
Agreed. I have both protected and unprotected cells and the protected cells all cut off at the correct charge and discharge points as they should have, pretty cool to verify it though. Thanks.
dallatorretdu Sorry but I lost your comment. I would use protected cells on lights that do not have internal protection. The Olight M22 does not have any cell protection so it is possible to damage the cell inadvertently. Thanks.
Just a note about the b6 charger; when in li-lion mode it will perform as it should by allowing the voltage to go to 2.5v/cell and will charge from that too. The only thing is it will only charge to 4.10 volts per cell in that mode
+Reuben Horner (LemonsFTW) Thanks for the information. I will test this on my charger with my meter. Thanks
it's great to watch such j formative videos for a guy who knows nothing about these high powered rechargables. Thank you! is there that much difference between the olight and the orbtronic?
+Michael Zaloom The Olight is my favourite protected 18650 but the Orbtronic is a very close second, here is my video on the Orbtronic 3400mAh 18650 protected Li-ion At Amazon: amzn.to/1GgUzjV To tell the truth there really is not a large difference. It's just a matter of personal preference not performance. Thanks.
I would recommend calibrating your charger. The copy versions of the iMax B6 chargers are not calibrated out of the box. In addition I would recommend getting yourself a DMM with a higher degree of precision. There is also some degree of rounding error in your multimeter.
+Ryan Donovan Thank you. I have purchased a more accurate DMM and the HF meter is surprisingly accurate. My Imax B6 is a counterfeit as a result I was not able to calibrate it but it too is fairly accurate too. If I decide to do more battery tests I will purchase a new charger Turnigy Smart6 80w 7A Balance Charger with Graph Screen at Amazon: amzn.to/1TJLiph and use my new meter too.
Similar price(£21) to the Panasonic here in England, and the price of Olight torches are well expensive to say the least, thanks for the video great as always.
You welcome. As it is said,"Sometimes you get what you pay for." Thanks for watching and commenting.
Hey Richard, I ordered the Olight 18650B battery three days ago from Amazon. Talk about two guys being on the same page at the same time. WOW! I don't know how but you and I are in sync. Anyway I also ordered the Olight M2S Javelot flashlight 10 or 12 days ago as well. The flashlight came with one Olight 18650B battery as well but I felt the need to pick up a spare one for the Javelot just in case I needed it. By the way the M2S Javelot has a throw of more than 800 meters using only one Olight 18650B battery! "Are you kiddin me" you might ask? There is NO othher light light on the planet that can do what this light does PERIOD! The Javelot uses a single XM-L2 1020 lumen led. I loved your video as well. I feel very confident using these protected cells in my new flashlight after watching this well produced video highlighting Olight 18650B batteries. Thanks.
I am impressed with this battery so far and compared with the Nitecore NL189 3400mAh battery I am currently testing. I have to say the build quality of this battery is superior as well as it's performance. Thanks again.
That's good news.
bendari Did you get the smooth reflector or the orange peel on your M2S? Looks like a nice light either way. Thanks.
As far as I know Javelot M2X only comes in smooth reflector. Like I said no other single cell light on the planet can do 800 meters.
Ive bought loads of Fake Ultrafire torches on ebay, and give them out to friends and relatives, two mini Q5s have astounded me on brightness with a 14500 battery, and they cost £2.43, thank god for China.
Excellent information! Thanks.
elbowroomtube You are most welcome. Thanks for watching.
Thanks, Great review ... why Panasonic don't put their name on their 18650 battery ?
Thanks for the informative video! referring to the discharge carried out, can you please tell me what does the number 03283 indicate.. Thanks
+Vivek Shettigar You are welcome. The 03283 indicates mAh which is the storage capacity of the battery. Thanks for asking and watching. I will put a note on the video to indicate that.
very good review.............. thanks
+SC Tjen You are welcome. Thanks for watching.
Let me ask a simple? Will this work on regular AA radios etc
No, it will not. This is an 18650 cell it will not physically fit. Thanks
You also have to check your charger as they will be designed for Ni-Mh or Ni-Cd and not Li-ion. Charging rates and voltages will be different so it is not compatible with the 18650 cell. Size difference is by design so you cannot accidentally charge it in the wrong charger for most chargers on the market.
THANK YOU.
You are most welcome. Thank for watching.
Nothing is better than OEM...
Im about to buy a multimeter. I have the option of the same you have (cen-tech red) for about 8$ and the uni-t ut33c for about 18$. Which would you recommend me? Thanks
+Yosue Caridad If you are going to use it regularly and not abuse it the uni-t ut33c is quite good. If you are going to use it once in a while and it doesn't have to be super accurate the (cen-tech red) more than good enough. BTW Here is a FREE coupon for the HF meter www.hfqpdb.com/harborfreightcoupons Thanks.
Thanks alot! Could have edit it down a bit, otherwise good job.
You're welcome.
Where do I get the black holder for the 18650 so I can hook it up to my imax B6? Got a couple of alleged panasonic cells incoming I'll probably have to test the same way to know if they're genuine or not.
+jairdabrini I modified this cheap charger by disabling the charge circuit and connecting the leads to the charge terminals, got it on Amazon: amzn.to/1qeVChE But if that is too involved for you, you can buy an 18650 battery holder and use that instead. Here is the link for one of those at Amazon: amzn.to/1Q0Ocnm Thanks
Richard Lloyd Thanks for the reply, often Amazon doesn't ship alot of the items they sell to sweden, so I'll check if I can get it from there - but at least I will know what to look for elsewhere (like ebay).
+jairdabrini Great. Thanks for watching.
Will this battery work in a LED LENSER F1R Flashlight ?
Roger Baker I do not own that flashlight so I can't comment directly. I suggest asking on Amazon amzn.to/1f3v9On and see what they say there. Thank you.
why must you use rechargeable batterries
Because they can be recharged. Thanks.
maybe I should have asked , why can't you use regular batteries ?
why can't I use regular batteries ?
No reason why not. If that works for you go for it. Thanks.
You can, but after one use you have to throw it out also the only closest equivalent primary to 18650 is using 2 of the CR123A but may not fit battery compartment always. This way if using rechargeable batteries we are reducing waste and you should be saving money as you can theoretically charge it 500 times and as long as electricity is cheap in your area. You could also buy a solar charger and that will be the cheapest and most environmentally friendly way to use batteries. There is an upfront cost of chargers and extra cost of rechargeable batteries but if your a heavy user of batteries this will pay off in the long run. Example cost of charger $12 (Nitecore UM10 USB charger- Amazon) cost of Solar cell for charger $140 (suntactics) cost of battery $16 (2x Samsung Batteries - Amazon) total =$168. Cost of primary (single use lithium battery $1ea - Amazon) 2x CR123A x 500 (uses compared to rechargables) = $1000. So it is a no brainier you will get your money back after 84 uses. Note if not charging often could be more expensive as the rechargeable batteries loses its charge over its lifetime, self dying batteries. Typically if your charging batteries often like every 2 weeks should work out more cost effective as these batteries should last 2-3years, however if your using 10 or more a year this will be saving the environment significantly as you will only be throwing 1 our every 2-3 years instead or 20-30. See ua-cam.com/video/kz6SmLC6Uk4/v-deo.html for solar charging setup. Great for flashlights as you use by night, charge by day or buy a second set of batteries, one for charging while your using the other.
I do not know what kind of affiliation (sorry, it looks like that) you have with Olight, or Amazon Olight sellers,
but making a review and not saying biggest flaws of Olight 18650 batteries is not OK if you want to do independent review.
kongo482 What flaw in this battery are you aware of that I am not? BTW I work for myself. I bought the battery with my own money and no one paid me a penny to do this review or any other video review I have ever done. I take pride in being able to say that. But even if I ever where to be paid to do a review I would still be honest about what I found. I did not find any flaw in this battery. It delivers on the advertised claims and I did not see any flaw in it what so ever. If you look at my Nitecore battery review ua-cam.com/video/TeEyRP80C-E/v-deo.html you will notice I was not as kind to it. I did find a flaw in it and I was honest about it. Thanks
Richard Lloyd OK, to be more specific. What is over-current protection limit on Olight 18650? That is most important reason why protection is on 18650 battery. Or What is max Amp rating that Olight 18650 protection will let you use, before tripping ?
kongo482
Specification:
Voltage : 3.7v (4.2v when fully charged)
Capacity : 3400mAh (discharged at 0.2C)
Standard charge 1700mAh
Standard discharge 680mAh (Cutoff at 2.5v/30mA)
Size : 18mm x 68.5mm (+/-0.2mm)
Current Over-flow protection : 10A
Weight 48g
Richard Lloyd Have you actually tried "Over-flow" protection in your tests?
kongo482 Not sure what you mean by "Over-flow" protection but if you can describe a procedure or give me a link describing the proper testing procedure and equipment for that, I am open to see if I can do it. Thanks.
I think your charger is the fake charger. The fake charger tends to read the voltage inacurately
LetsGetStarted I am on the fence as to whether there is a fake version of this charger or not. I am of the opinion that they are all made in the same factory and some people stick a holographic sticker and charge an extra $20 for the same charger (I may be mistaken). I think my issue is the length of my wires and the light gauge of the wires I used on the battery holder. I am going to increase the gauge of those wires, shorten the length and put banana plugs on the end bypassing the supplied wire so I can connect them directly to the charger. That should help with the error. BTW the middle point between both readings are usually spot on. Thanks for watching and commenting.
Richard Lloyd You might be right in saying that they may have been made in the same warehouse but there is DEFINITELY!!! a difference of the board and the adapter (for the B6AC) i bought the B6AC V2 Yesterday.
LetsGetStarted Looks cool built in power supply and PC connectivity, very nice. Did you see the WIFI module? See what you did now? Now I am itching to buy one, dang! Where did you buy it and how much? Thanks
Richard Lloyd I bought it for AUD$62 from www.hobbywarehouse.com.au (they ship to Australia only i think) The shipping was about $10 so the total price for me was $72 (it is genuine) Its the cheapest price i can see (in an Australian warehouse) It is on discount at the moment (from $129 incuding shipping). I wanted to get it quick so i ordered it from an Australian warehouse.
LetsGetStarted I should buy the cheapest V2 from Ebay and then we can compare the two as far as packaging and exterior build and even internals if you want to take it apart (Pictures).
PS fake iMAx B6, so your measurements will be off
Why keep referring to it as a 'battery'? It is a cell!
"An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices."
Thank you very much.
always check the EAN UPC bar codes
45 + 49 Japan distribution center (legit)
489 is hong kong (fake)
Yours was oily when you took off the package? I've brought a Olight i5R, wich comes with this battery, and it was oily when I opened the package.
No mine was dry. I do not believe they have oil inside them so I have no idea where it would have come from. Thank you so much for commenting and watching. I appreciate it greatly. Subscribe, Click The Bell and stay tuned! All the best.👍😀
Excellent review. Thank you so much!
+Valerie Lee You are welcome. Thanks for watching and the kind comment.
A great video but POSITIVE CATHODE AND NEGATIVE ANODE????? , SURELY NOT :O)
It's an alternate reality....Thanks for bringing it to mind. All the best.
wow....why ''not'' use batteries recommended by the manufacture? I'll use OLIGHT batteries in my OLIGHT flashlight. Learned a lot. thanks!!
Some one need the battery unprotect but some one need the battery protect. So witch one is better.
Protected cells for devices that do not have protection built in and unprotected cells for devices that have built in protection. If you don't know if the device has it or not go with the protected cells every time. My suggestions of course but stay on the safe side when in doubt. Thank you for watching and commenting. I appreciate it greatly. All the best.👍😀
I seems to me your Imax B6 charger may be a fake, which might explain the voltage discrepancy. I have both and can see some of the tell tale signs like the different buttons and label alignment, and like yours my fake one is also less accurate. There are heaps of youtube videos about just as many pirate variations of this popular charger.
Thanks. I now know it's a fake but it is a fairly good fake and works quite well but I do understand that there may be some inaccuracy in it but from what I can see it is quite accurate. I will be using it again to test some 9900mAh 18650 red cells from China, more as a public service than anything else as I know they will be no where near 9900 mAh but the charger will be close enough to tell you how badly they are ripping you off with these cells. Thanks again.
Really informative video, thanks so much =)
You are most welcome. Thank your very much for commenting, watching and the kind words. All the best.
Hi Richard great review as always ! When will you be posting up a review on 18650 orbitronics 3400 mah batteries?
Yes Sir. Here it is ua-cam.com/video/pYtxHnfG7Is/v-deo.html
Great video sir. Nice and direct and to the point. I found a olight and charged battery it works great.
Thank you so much for watching, commenting and the kind words. I appreciate it greatly. All the best.👍😀
richard can you help mee out? i want to replace my dodgy drill battery
part number: POWX0057
Brand: powerplus
Voltage: 18V
mAh: 1200
L shaped battery with 1 battery on top
how much 18650 battery do i need and what charger do i need to charge it and i want the mAh to be the max
thanks in advance
I may make a video on how to do this as I have a NICad cordless drill and NICad chargers for them both. I find their capacity limited even when brand new. I will do some research into it. I believe it will either require a BMS or the use of a balance charger. I am thinking the balance charger arrangement would ber the simpler but I am just speculating at the moment. I will put it on my possible future videos for consideration. Thanks for asking. I know I did not tell you how to do it but it would be far easier for me to show with a video.
thanx in advanced richard ill be looking forward for the diy vid ill keep track of you with that big red butten :-)
I was hoping you would open up the battery to see if it was in fact a Panasonic battery.
Hi, thanks for the vid. I was looking to buy the 3600 mAh version (www.olightstore.com/batteries-and-chargers/olight-18650-lithium-ion-3600mah-battery). I don't see why not at only a couple dollars more (for a battery you recharge 500 times). Do you think I can expect the same performance and quality, or would it be safer to stick with the 3400 mAh's?
I have not bought the 3600 mAh but I trust Olight to make a quality product. I can't see why the 3600 mAh battery would be any different in quality. Thanks.
They are excellent batteries. I have one exactly like that on my Lumintop SD Mini.
It rocks!
Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.
Those are not 18650 batteries. 18650 must be 65 mm long not 69 mm.
just because it holds capacity doesnt mean it's good. Cheap cells will depreciate quicker than a good cell. Also have reliability issues like cannot deliver 1A and tapers of to 0.5A-0.2A. I have a few cheap cells that have 1500mah, but 500mah of that is acheived at 0.5A. This is the case with a lot of cheap replacement batteries which causes the laptop to sudenly die -due to the fact that the laptop current get the desired amps. The BMS in these batteries aren't very smart so it cannot communicate with the laptop that the amperage in the cell is unreliable therefore likely to suddenly lose power.
+OnlineBackupServices The core cell in this package is a Panasonic NCR 18650B so I trust them to be reliable and the highest quality 18650 cells available on the market. Thank you.
OK thank you. Let's start. Talking about performance. What is max current load that NCR18650B (unprotected green cell) will handle?
kongo482 Here are all the specs from Panasonic. www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCYQFjAB&url=http%3A%2F%2Fna.industrial.panasonic.com%2Fsites%2Fdefault%2Fpidsa%2Ffiles%2Fncr18650b.pdf&ei=nsBCVe2ODo24ogSr7YBo&usg=AFQjCNH0yxmuCXn16yErAuQATsSKkcDc3Q&sig2=idZ4oyI8pWRCtInESYYPrQ
Richard Lloyd I know what is NCR18650B max load rate : 2C = 7 Amps. But in Olight 3400mAh specifications Maximum Discharge Current is 4.2 Amps only. Did you investigate at what current load Olight protection will trip?
I believe what you have therein the pale green cover is SunLabz® 18650 3.7V Rechargeable (4-Pack) Flat Top Battery Cells 3400mAh from Amazon.
Can you tell me the difference between 16340 and RCR 123A and there are other 123 batteries. I find it confusing.
This is a great resource for all things battery and flash lights: www.candlepowerforums.com/vb/showthread.php?235164-Using-Li-ion-cells-in-LED-flashlights-safely Thanks
don`t solder anything on your 18650 , there are small iron magnets just for that, and very cheap, like 10 cents /piece the size of a small washer, the same place you buy your accus.
why? how you going hold 10S 18650 ?
himano loganor
the small magnets are cylindrical and covered in chrome to conduct electricity, they have the role of replacing the missing bulbs on the positive side of the accus so that you can use them in flashlights.
Can I safely use my 5V phone charger to charge a Thrunite Protected 18650 3400mah?
Forgot to tell you that the protected 18650 cell is for use in a flashlight that will shut off when battery voltage becomes too low.
Thanks for the video and the information. Excellent review.
+assemshawkat You are most welcome. Thanks for watching and the kind comment.
thank you very much richard this is a supreme video of proof and testing
You are most welcome. Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.
I have to buy a pair of 18650 batteries but what most good NiteCore or olight
I would say either one would be a good choice. I like the wrap on the Olight better but that is a superficial consideration. I would go with the one of the two you can purchase at a cheaper price.Thanks
i would buy samsung cells, extremely good quality at a reasonable price
I bought these batteries for vaping based on your review and man, what a performance! Thanks
Nitecore doesn't fit most mods. Does this fit in mods?
Very informative review Bro!....thanks a lot
You are most welcome. Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.
hello,,,if im making a boom box an wanna use these batteries and seal the box which charger would I use to put inside the box so I can re charge when flat and are these batteries fire safe , are they protected against exsploading , thanks
+rogueartmusic The short answer is no. Thanks.
Thank you for the informed, thorough presentation. I would only suggest in order to isolate the readings variables, use a Fluke or equivalent grade meter, and compare reading between different DMMS. (I don't find Harbor Freight to be very reliable for too much beyond their 7 & 9mil nitrile gloves. ) I buy my Olightts from kathryn-md at ebay, one of the very best sellers there.
+Ob1 Zenobi Thanks. I have upgraded my DMMS too but not to the level of the Fluke yet Mastech MS8229 Auto-Range 5-in-1 Multi-functional Digital Multimeter At Amazon: amzn.to/1VFztqA and Mastech MS8268 MS8261 Series Digital AC/DC Auto/Manual Range Digital Multimeter At Amazon: amzn.to/1VFztXI But they rate highly on Amazon. I know the cheap Harborfreight meter is an easy target but it actually is usually spot on with the other meters when I compare the readings (surprising). Thanks for the feedback and watching.
Your IMAX B6 isn't a trustable device to measure
+Jose Silva What would you recommend? I know the IMAX B6 I have is a counterfeit and I may make a video on that soon. I am looking at the Turnigy Smart6 80w 7A Balance Charger with Graph Screen at Amazon: amzn.to/1NEDq6y looks like a very good buy and a cool charger. Thanks.
Nice charger.
What are the features?
I need one to test my cells
Can u use these in vape mods? Safely since high drain
this and your Nitecore and Orbtronic reviews are some of the best I have ever seen. I must have a dozen of these Olight cells and have always wondered about them. I buy Orbtronic now but its very good to see these Olight cells seem to be a bit above average in performance!
Bryan McHugh Glad you enjoyed it. Thank you very much for kind comments and watching.
is it true that using a protected battery in my blf a6 flashlight wont get the full juice as using an unprotected? Im about to buy the samsung inr18650 30Q. Between this olight and the samsung 30Q which one will give me more light power and duration
Thanks
+Yosue Caridad Not true. The protection circuit protects the battery from overcharging over discharging and short circuit. It does not affect the power output otherwise. Thanks.
+Richard Lloyd thanks a lot
+Yosue Caridad You are welcome. Thanks for watching.
I really hate thinking about what can happen with those unprotected cells- the downside makes them not remotely worth having imho
Fantastic review. I am currently using eagtac 3400's. After watching this, I am using your link to pick up a few of these batteries.
Thanks again for a great review.
+jr10 BTW. As a follow-up, I was reflecting on the part of your video where you mentioned that your SkyRay would work with one battery. I was curious and thought the similarities between your light and my Nitecore Tiny Monster TM11 were very close. I was shocked to see my light work with one battery. Thank you sir.
+jr10 You are welcome. When I saw the cells where connected in parallel, I was both surprised and impressed as it gives you flexibility to use one to four batteries. If you are in an emergency situation and all you have is one cell this light will work where others will only work if you have the complete set (be it two, three or four). Also you can pace your cell usage by using one at a time till it wears out and then replacing it with a fresh one. That way you know when you are on your last cell. Very nice. Glad I could help. Thanks for watching and commenting.
+Richard Lloyd A test on using one battery vs 4 would be a good test, to see what the difference is
Maybe the built in battery protection circuit is preventing it from going lower than you are trying to take it.
+Ken Franco Perhaps but that would limit the amount of energy the cell could provide. Thanks.
Nhh
I read in the instruction guide of a charger which looks similar to this (Imax B6AC) which advised against using it for batteries with protection circuitry. Unless the circuit trips it seems to work fine, not sure why else they warn against it.
+tombell12 No idea why they would warn against it? The protection circuit is there to protect the cell so anything bad the charger may try to do to the cell would be canceled out by the protection circuit (hence why it's there). I have not had any problems with protected cells on my Imax B6. Thanks.
+Richard Lloyd As far as I know, one at a time. Thanks.
Is the olight 3400mah battery the best 18650 for flashlights (Fenix TK16)
+JAY LEE Not sure if it is the best cell for the flashlight but it is an extremely good one. I am sure it will work well with it and that you will be happy with the performance. Be sure to use a quality charger with it too. Thanks.
+Richard Lloyd Ill have to get one, I have a bunch of 18650's all unprotected for vaping, for now Ill just use my Panasonic 3400mah.
Im using a Nitecore D4 charger
+JAY LEE Since you are using the Nitecore D4 charger there is no chance you will overcharge so if you are using unprotected cells the only things you need to worry about are shorts and draining them too low. If you are cognisant of those two factors while using the Panasonic 3400mah cell you should be fine. The protected batteries basically make it a no brainer. Thanks.
+Richard Lloyd Thanks for the info Richard!
+JAY LEE so these are better than Fenix's branded 18650 3400 mAH cells that are selling for over $20 each?
You have a fake Imaxx b6
Michael Langell I have had this discussion on another video. Basically fake or not I am happy with how it works so it does not really matter to me. I got it for a good price and it is still working great today. Thanks.
Very informative. Thank you so much!
+Jay Estrella You are welcome. Thanks for watching.
richard super

+Jason Etcheson I do not vape so I really can't comment on it. Go to the Amazon page and look at the reviews : amzn.to/1ENCQQj they may have some relevant information. Thanks.
Excellent video!

Thank you very much.
can u test the ebay 9900mah 18650 red batteries
Just ordered a pair and will do a video review when I receive them. Thanks.
Nice :) thanks
GTF are garbage 500mah max chinese scam.
I am sure they are and when I review them we will see what their true capacity is. Judging by the weight alone I can tell they are going to be bad. Seeing as the largest capacity 18650 currently being manufactured (that I know of is 3500mAh) you know it's a lie, but how bad a lie? LOL we will see. They might as well label them a Gazillion mAh (dilithium crystals not included). All the best.
Yeah what a joke, i received mine yesterday and the weight on them was extremely LOW.... to put it mild, cant wait for your review and see what the truth really is.
