Great tip! Paid $10 buck for an 18 volt battery and in my case the HF battery cells fit directly in my Black and Decker pack. I just had to un-solder the wires from the HF connector and re-solder to the B&D pack. Works great.
i LOVE THE WAY YOU SAVED SOME MONEY BY THINKING OUTSIDE THE BOX. tHE INSTRUCTIONS WE CLEAR SO EASY TO FOLLOW. THANKS FOR SHARING YOUR KNOWLEDGE.
Thank you kindly. HAPPY New Year. Cheers
Not really that impressive,
Basic Electronics, i was doing this by the time i was 10 years old back in the 80s
I never knew about the ability of renewing an old 18V battery pack. I'll never have to buy an expensive battery for my Ryobi again! Very good learning tool! A+
Glad i was able to help. Cheers
don't tear the tab off of the battery ends, cut it in the center with tin snips to leave a tab to solder to so you are not soldering to the battery itself
Thank you for the tip. Will do next time. Cheers
Thanks for ur helpful video. İ have no good english as much as to understand ur speaking but i watched ur video with pleasure until end. Greting from turkey.
Great video, well paced, good description without being too detailed, and without skipping over anything. Very informative, and exactly what I was looking for. Thanks Peter.
Thank you kindly. Cheers
Surprising I haven't come across this before now, thank you so much for sharing, can save a ton of money now lol
Cheers
Great vid, I've got an ebike that had a defective battery , among other things when I bought it from evelo. They refused to replace the bike, and continue shipping me the parts I needed to fix it, because I seemed mechanically inclined to them. I've had the battery out of the bike several times to inspect it, and realized just what you are explaining here. Now I'm sure that I have the rite idea, just save myself almost $1,000 (what they want for a new battery). Thanx bud, I'll let you know how it goes when I do the surgery. The bike was a lemon, they didn't understand what that is apparently. $3,400 for the bike new, I'll not work with them anymore, very arogent & condescending staff. You rock!
May I suggest that in the future you use flux before you begin the soldering process. This will minimize the amount of heat required and reduce the possibility of damaging the cell from overheating. In addition it looks like you are using a soldering gun, which could be 100 or 200 watts (could not determine from the video). I would suggest you invest in a soldering iron of about 40 - 50 watts, especially if you are doing this on a regular basis. This smaller heat source and the use of solder flux will greatly reduce the chance of damage.
I thought this was well done and will try this on a couple of older batteries that I have not, thankfully, recycled yet. Keep up the good videos, thank you.
Thanks for the education on replacement on these types of packs!
interesting points ,if anyone else wants to uncover how to recondition my car battery try Vaxicorn Battery Extender Guide ( search on google ) ? Ive heard some amazing things about it and my mate got amazing success with it.
en use a rubber band to brace the battery while in the state of assembly
Hi, so if a few battery is bad then the whole pack wouldn't work and if you change out the bad one with fresh and the pack will work again, is that the idea? I been throwing my money away.
@@michaelwoo5728 that's the idea, the pack was working but it was low on voltage because of the defective cells
have found that bundle style rubber bands free from post office holds the packs well. also tinning the wires before attaching works well. i have the third hand to aid me. new cardboard cutouts was a cinch. used non conducting tape to hold heat sensor and moved that pesky wire next to connection. worked out well.
Hi Peter. I don't care what the haters had to say. I think this video was very useful and well thought out. I like it when a person takes the time to explain every movement involved, than the lazy ones that just play music show the item move this and that not explaining a thing expecting you to know what they are doing. Wish more would do videos like you. I had stumbled on this video by accident and Glad I did. A few months back my Ryobi cordless 18V battery pack wasn't staying charged have 2 battery packs. I looked online for replacements and seen the prices and held back on getting any. This video is an answer to my problem. I like saving a dollar to. Plus I like fixing things this will be another piece of knowledge for me to put to good use and share with my friends. Keep up the Good Work Peter. You've got my Vote. and New Subscriber my friend.
Thanks so much. Cheers
This is exactly what I was looking for. Brilliant idea buying from harbor freight for a bargain price. You made an excellent video. Thanks
Awesome. Thank you so much for viewing and commenting. Cheers
@@PeterZafra 5 6th 4 they went
Great video Peter. I should have searched UA-cam before I tried to use some Wire Glue from SureHold. I have tried to solder the strips to batteries in the past resulting in very poor solder connections. In watching this video, I see that your technique was to get
a good spot of solder on each of the battery and the nickle strip first and then attach the two in a third step thus reducing the amount of heat applied to the battery. Found it just in time. I have a coleman drill in which one of the battery connections broke. Will be following your example to repair. Thank you very much for taking the time.
Cheers. Thank you
Good DIY stuffs. This is a great way to save some bucks. Thank you for sharing.
i have nothing but time on my hands, very good idea. will try this for sure thanks
Thank you. Take care. Cheers
I have spent months researching into battery reconditioning and discovered an awesome resource at Magic Mender Wizard (google it if you are interested)
Awesome Peter, thanks for sharing this. I will try it as soon as I can. Be careful when you are soldering with that flux core solder. The smoke is very toxic, because flux acid melts out of the inside and cleans the connection so the solder will stick. Keep up the great content.
Cheers.
Thanks for the video, I enjoyed watching though I won't be trying it anytime soon, you have a good knowledge and plenty of patience young man 💖 .
Thank you kindly. Cheers
Those batteries dissipate a lot of heat during soldering and you soldered them easily without flux with your giant iron. Great tip on the HF battery.
Thanks for the info
thank you, Peter, a very good idea, I shall attempt the procedure, as I just happen to have a harbor freight battery of the which I lost the drill, so my
Dewalt drill has a dead or defective battery so game on! thank you and God bless
It's worthit. Cheers
Interesting. I never did battery pack "Rebuilds" when I was the Guitar Doctor at Stars Guitars in San Francisco, CA., but you might want to point out for those totally unfamiliar with the difference that in electronics you use Rosin Core solder [rosin is the fluxing compound inside the solder] and not Acid Core solder [where acid is the flux inside the solder] as you would use on copper pipe for example. Yes, you always "Tin" the wire [stranded or solid core wire] first before you attempt to solder it to a connector, etc. The same with a connector you're trying to attach to a metal part - tin the connector first, not the metal battery cap. While making everything clean and neat, yes, you do need to leave just the right amount of slack. The "Heat Sink", as you call it is actually a thermal-couple of some kind if it does what you say it does. Bye the by, "Chicken Shack" [if they're still in business] sells a small pair of wire strippers for electronic applications such as this that are a whole lot easier to use one handed than the kind of monsters usually found in your typical auto-parts or big box stores. Hopefully your soldering gun has a half power setting and it seems like painter's tape could hold everything together while you try using your third elbow when soldering things together.
Nice and informative. I have a dustbuster that needs some love like this.
excellent tutorial. Thank you for posting.
THANK YOU FOR SHOWING US HOW IT'S DONE ! BE SAFE ! HAVE FUN ! GOD BLESS YOU ALWAYS ! ENJOYED !
Thank you. Cheers
Great hack! I can't wait to try it out on my old batteries.
Yup. Its great. Thank you for watching.
Extremely helpful. Thanks.
an old video but very valuable every time for many reasons, but the most important one is how to tweak the system
thanks tho 🕵
Yes indeed. Old video. Thanks for the view. cheers
peter use solder flux when soldering it makes the solder flow much faster especially when working on battery"s no chance of over heating the battery. great work!!!
Thanks for the tip. Cheers
i refurbish dead tool batteries for a resale warehouse as one of my side gigs. i use hot glue to hold the cells together in the desired configuration. i also made darkkevind's spot welder to connect the individual cells. no worries about over heating the cells that way. i only solder to the nickel ribbon, never the batteries themselves. the welder works quite well, it is a very good design. just make sure you get pure nickel ribbon, not nickel plated steel.
Touch of miss's nail varnish on the solder joints and wires, helps to keep them connected and offers some insulation!
Thanks. When I rebuilt a battery I bought new cells and I had a hard time connecting them all together because I couldn't get things hot enough to melt the solder to get good joints. This is a much quicker way to go.
Glad it worked out. Cheers
You can buy battery cells with tabs already welded to them as well.
Thank you for showing, now I know that I rather buy a new pack.
Hahaha. Thank you for watching. Stay safe. cheers
Best thing to do firstly is, see if the solder will adhear rightful, before starting the project .
Great!’ I’ve got a couple of Dewalt 14V packs that are long gone and the drill still good. Costs $94. per battery to replace.
Awesome. Try to wake them up and if that doesn't work, change them out
Tip 2: when reconnecting the top cell first add solder to the button and the bottom of the connector before putting them together. All you need to do after is reheat the connector to make the solder flow together. ( by the way solder what the rest of the world uses instead of US soder)
Tip 3: Don’t blow on the solder. Let it cool naturally to reduce the risk of poor joint due to “cold solder joint”. If the solder is smooth you have a good joint. If it looks crystalline, reheat till it flows smooth. Cold solder joints can cause loss in power and extra heat in the battery pack due to greater resistance through the joint.
Tip 4: tape the temperature sensor to the side of one of the batteries. Any air gap changes the actual temperature measured and therefore changes the switch off time. You want to measure the battery temperature, not the air temperature within the pack.
I would be interested in the mAH rating of both the old battery cell and the new. You will probably find your cheap cells are rated less than the originals.
Thank you. Cheers!!!!
Yes, "cold solder joints" were a problem in the early US NASA space program, until the technicians were taught by the old von Braun German team about how to make flight-ready joints. Basically, both surfaces must be held together and not moved until the joint is hot and the solder melts, then held completely stationary and motionless until the solder cools and becomes solid. Holding a wire in your hands is asking for trouble, as not many have such steady hands. If the cooled joint has a porous, dull color, it will not have any mechanical strength. Cold solder joints can break apart from vibration. A good strong solder joint has a bright shiny look.
Thank you for the video. Absolutely is very good
The best part of this video is finding out harbor freight sells a nicad battery pack for $12. That is so cheap and so convenient to buy locally. The cells are also somewhat vetted for quality which is way better than a random ebay seller selling cells that might be really old (at a higher price than this). Thank you
Yes
@@PeterZafra I rebuilt my battery pack and the cells work perfectly.
Im sitting here looking at 5 of these batteries that are dead. I cant wait to fix them. Thank you.
Michael Jordan awesome. cheers
Don't just replace 5 lol replace them all ;)
Michael Jordan ppl
Should glue the clips to batteries to help assemble or weld easier Thank for this demo :-)
very instructive but I couldn't help thinking when I saw it in action you just could've got a broom lol
Great video. Very informative and quite ingenious. Thank you for your DIY project.
Thank you kindly. Cheers
Tip: Cut a length of solder-wire for soldering, and use the spool as a battery holder. (Large, adjustable pliers with an elastic band is good too.)
Thanks for the tip.
A Third-Hand tool works great at times as well.
A zip tie wont conduct a short on ya.
Awesome presenter!!! Better than any others I've scene!!!
Thank you kindly
Useful Video, It could be worth taping the batteries together for stability while working with them, also to tape thermistor to the pack before reinstalling.
Thank you for the input. Cheers
Nice video, Thank you. For future reference you may want to find yourself a 500 ferad super cap and two 12 ga. solid copper wires, (and a pack of nickel terminal strips) filed to a blunt point. Solder them to the caps' terminals and that will give you a cheap and efficient terminal spot welder. It will produce less heat and no chance of battery damage due to soldering, It works very well.Good luck👍
Thank you. Cheers
coupla pointer on soldering to the battery itself ; 1. ALWAYS tin the battery after sanding a bit or using a small file to knock those pointy leftovers on it after you tear the flat ribbon jumper off it , also sand /file the ribbon and tin first , then when you apply heat they'll just join quickly with a bit more solder 2. forget that big stupid high wattage solder gun thats guaranteed to overheat the battery and get a quality 60 watt iron(pencil) , you'll thank me for it , controlled heat that stays on , so youre not dickin around waitin for it to get hot every time .
Thank you for your pointers. Cheers
One thing you did not mention, was that the HF battery does not have
POWER of the original battery. You can tell by the weight - the HF one
is A LOT lighter than the original. The original actually feels HEAVY.
This means it won't last as long on what ever job you are doing. But,
I like it! and will use it on a couple of Craftsman batteries I have laying
around. I do have a bit of a complaint, while do a good job of your step
by step, it is too long - you could cut a lot of your redundant verbiage.
All in all, you did a good job of it, and gave me a good idea. COMPLETELY
agree with Lei below. tnx
Yes. It does weigh less. It's a great move for older drill set up. Cheers
Great information,thank you.
Hello ! Have you ever heard about FLUX ? FLUX is your best friend if your soldering components ! Makes it easier soldering !
And clean your soldering iron tip and do solder on it so you can better solder and protect your solder iron tip !
Best regards, thank you for your informative video !
Thank you for the tip. Cheers
thanks for showing us your yard
Great idea. And a good video! Thanks.. O the music was loud.
Your hard work is enjoyable.
Thank you. Cheers
I gave you a thumbs up and subscribed as soon as I saw that RadioShack soldering iron... 😎
Thank you for the support. Cheers
thanks, very informative, I have 4 of those batteries and now know how to fix them.
Cheers. Yep. I still have these exact batteries still working today. :)
Great video! I learned some from you. Thank you for sharing.
Thank you. Cheers.
Thank you! Sadly I can't find those ultra cheap 18V batteries here in Germany, but what I can find are 18V 3,5Ah 20€ Bosch replacement packs.
I will use the cells to rebuild my pretty rare (~75 for replacements) Hilti battery pack. Thats actually a great deal because single NiMH (or NiCd) Sub-C cells are pretty expensive at around 3€ per cell. that would make 39€ worth of cells for just one 13 cell (15,6V) pack
Glad it helped. Cheers
Thank you for the info. I saved, and subscribed. 😎
Awesome. Thanks so much
i found to hold the battery pack to together while working on it, was to put a rubber band around the pack so it dose not short out.
Thank you. Great idea. Cheers
hi everyone ,if anyone else is searching for reconditioning lead acid batteries try Jons Mender Guide (just google it ) ? Ive heard some incredible things about it and my m8 got cool success with it.
Very informative. great idea. thank you for the video, I will definitely give it a go. 👍
Thank you. Cheers
Regarding soldering and or spot welding the cells. A spot welder can do damage and so can a soldering gun. The spot welder can make punctures. The soldering gun has a skinny tip which has only a small amount of thermal inertia. When you apply the tip to the work the heat is almost instantly drained away and you have to hold it there while the tip and work heat up. This can cause internal battery damage. I suggest using a small 40 watt soldering iron with a big tip. The tip has a lot of thermal inertia so won't cool down too quickly as you apply heat to the cell. The outside of the cell and the steel conductive tape heat up fast enough that the cell contents get very little if any damage. I use the same strategy when installing RF connectors to coax cable for my ham radio work. What a difference. I used to use a gun and it would heat and melt the inside plastic separators in the RF connectors. All the best fellow do-it-yourselfers.
Thank you for the heads up advise. Cheers
It looks like you didn't solder directly to the cell, it was to nickle strip and a button-top. To solder directly to the cell, one might want to use flux and cooling sponge. The high temperature iron is good apparently because while the surface gets hot very fast, it does not conduct inwards as quickly. DiodeGoneWild and MrCarlsonsLab have videos on soldering directly to cells. Made more recently though, and this does show you what's in the Ryobi pack! Thanks for the video!
Great tutorial video
Helpful video. I would suggest removing any metal watches or rings whilst handling battery packs as you could end up with a severely damaged wrist of fingers.
Thank you for the input. Cheers
@@PeterZafrayour welcome. Batteries are merely a electrical storage device much like a capacitor. The only thing that stops them fully discharging in one go is a load. For example a light bulb. Although small this acts as a load. The wire to the bulb depends upon the amount of current the load(bulb) draws out of the battery. So if you have no load and accidentally short across the + & - with a ring, watch or any other metal tool or device, it basically acts as the wire thickness. A ring would draw extreme current as very thick. Hence sizes of fuse wires. A ring would very quickly get so hot it would probably burn through to the bone in seconds. Same with a metal wrist watch. General rule is not to wear them and keep metal away from the + & - of any size battery in case of a accident. Keep safe. Still a good video to explain the way you can save pennies if needed.
@@adrianleighuk RIGHT !!! Also, as soon as the wires are disconnected, they must be insulated for any work around them...
Great video!
Love the RADIO SHACK SOLDER
Yup. So rare now
Very helpful step by step you are a teacher
Thank you kindly.
Good video and some good points have been made below about using flux to reduce the chance of heat damage. Also, make sure not to toss your old battery packs into the trash as all rechargeable battery packs recycle. If you toss them into the trash they can cause a fire if they short out. Place them into a plastic sandwich bag and give them to a recycling center (most electronics store will take them).
and HDs and Lowes.
Always remember to use a small heat sink alligator clip between the battery terminal clip and the end of the wire you are soldering so it can wick the heat away from the battery to keep from over heating the cell...
Thank you for the pointer. Cheers
Great video, I'm gonna give this a try. Thank you!
Always good to make do and mend. Your soldering technique needs a little improvement though. Never ever blow on a hot solder joint,,,,, always let it cure at its own speed. This can cause cracked or dry joints.
Might be worth investing in a small spot welder for better current transfer on those bridges.👍🇬🇧👍
Great instructions
It's a good thing you didn't mix cells from both packs together, the Robi's could be 1Ah, 2Ah or 3Ah vs HF 1.3Ah.
There are "Ryobi replacement packs" for the P100 One+ (not Ryobi), 2 for $32 vs the $13 HF battery pack.
That's nearly 3x the Ah for $3 more, or you can get a single P100 3600mAh "Ryobi replacement pack" for $19. No fuss not muss.
Even buying 15 sub-C batteries online would offer better value than the HF $13 pack these days.
You have the flexibility to create a pack with the number of Ahs you prefer.
The more Ah per pack means the longer you can run that tool without recharging.
1Ah means you can expand 1 amp per hr before you have to recharge, 3Ah means you can expand 1Ah for 3 hours, etc.
How long you can run a particular tool depends on how much energy that tool requires to operate.
If it uses 1Ah/hr, then you can run that tool for one hr, but with a 3Ah battery, you could run the same tool for 3 hours.
amazing congrats!!!
Excellent.
brilliant....cheers from UK
as a wood butcher I chose Ryobi early on and now have 10+ dead batteries. I can never catch them on sale and they are $40 each here. Am going to get this done ASAP. Thank you for walking me through this. do you save the old batteries for franken-pack or just new set up?
Good video and Thanks for sharing .
Cheers.
Interesting video. A little clumsy handling at times. Job well done.
how to rebuid your old rechargeable good job
I got a question.. i got 4 battery packs, all are Ni-cd, wondering if i can connect them
3 battery packs are 4.8v(4 AAbatteries per pack) and the another 1 is 6v(5 AA batteries)
Would it be safe if i unsolder them and create a custom batter pack? For example, taking the 5AA batteries and connect it to the 4AA battery pack, is it safe to use? I tries it bur after connecting to an rc vehicle, the motor starts smoking, am not sure if it will explode because i took the battery right away.. not sure if i did the connection of the 2 battery packs correct..
I know you are very competent at soldering battery packs, but to keep the heat off the new cells. Would it be of help to pre tin the connections or are you concerned about too much flux floating around? What happened to the shorted out cells? Dave M
Good Video, You Can Also Pull Your old Batteries Apart and Keep The Good Cells - Take some Pictures Of How They Were Originally Joined and Join The Good Cells Together To Make a New ( ISH ) Battery
Thank you. Cheers
Really good video. Thank you.
Thank you. Cheers
The “Heat Sink Thinky” is a PTC or NTC thermistor. Regardless of packs of rechargeable battery technology, the circuitry needs to know if the battery(s) temp. If too high, recharging will be denied and delayed until they cool down. The thermistor changes resistance with the temperature. One simply goes high resistance when hot & the other goes down. Also the voltage of the entire pack is monitored internally as Li-Ion batteries are not discharged below 20% and not charged above 80% of the packs total voltage rating. This is the same for cordless tools or battery packs used in vehicles whether totally electric or Hybrid.
Yup. These are Ni-Cd not lithium.
@@PeterZafra Thank you Peter Zafra and Dean Kay for the info. One question: If I charge until it thinks its charged; then unplug to cool down; then charge some more; cool; charge, etc. Will this give a higher charge? Or, since we are in this "lockdown" period, maybe I'll just replace all with new HF pack. As Peter shows they are so cheap!
Very cool idea!
Thank you. Cheers
Try using some flux material to etch the surfaces clean. This will lower your heat ranger equipment and ensure a great solder flow with connection fractures. Which “will” happen if you man-handle the tool battery. Actually using flux on all connection surfaces prior to flowing solder is Soldering 101.
Yes. For sure next time I will. Cheers
Nice job...GOOD WORK...THOROUGH!!! When Harbor Freight 1st sold batteries...9.6v...I TOOK ONE APART...THERE WAS A WET PAPER TOWEL IN IT TO MAKE THOSE FLAT MILD STEEL BATTERY CONNECTORS RUST...HARBOR FREIGHT SOLD HOW MANY THOUSANDS...BAD BAD BAD...MY SUGGESTION...CHECK EVERY BATTERY YOU GET FROM THEM 1st...grrrrr
Nice video. like the old radio shack gun and solider. can not get them anymore.
Yep yep. Cheers
What kind & size welder did you use & what was it set at
You should use flux to solder it works a lot better.
And tin both parts first before soldering.
Scuffing the metal with some medium/fine 240 or so grit sandpaper makes the solder stick a lot easier too. Just give the metal a scratch pattern for the solder to grip to. Plus sanding removes any oxide layer that you might not even be able to see.
Nice work
Thank you. Cheers
Great job
Thank you. Cheers
Good demo
Cheers
How about using some tape, or a thick rubber band to hold the pack together while you're working in it?
Yep. That would work. Cheers
Thank you for this very informative video! I do have one question; can
you comment on the overall capacity of these Harbor Freight batteries as
compared to (for example) the original DeWalts? If I understand what I'm reading on
the internet, the DeWalts are in the range of 3,000 or 4,000 or 5,000mAh
while the Harbor Freight seems to say it is 1,300 mAh. SO, if this is
accurate, your rebuild would be of much lower capacity. Am I reading
all that correctly, or is the comparison apples vs oranges?
Hi. Thank you for watching. Yes. These cells won't last as long as original but it definitely lasts pretty long. I would say at the least half the time. I still have the same cells and they are still working really well. Cheers
Excellent. Thank you..
Thank you. Cheers
if you compare the price of an off-brand ryobi replacement with the off-brand harbor freight unit, the savings is less. so might you want to consider this rather than the hour+ [this would probably take me at least 3 hours] for this rejuvenation? I do applaud this fix for its better sustainability.
Yup. I agree. This was almost 5 years ago tho. I think the knock offs came after but yes, I agree
Think I would have turned the 2 batteries over so the - tab would be up top and the red jumper you ran from the bottom would be on top also but that's just me.
That would have made much more sense. I was baffled by how hard he made it.
My only comment is that with the wiggling around of the wires while you're soldering you're fortunate that you didn't end up with any cold joints. Other than that concern, it was an informative video.
Thank you. Cheers.
Hey Peter ! Great video , very informative , i hope when my stuff goes bad i can be able to do that too , even with my snap on products ! thanks
Thank you. Cheers
Thank you good job
Cheers
If you flipped the 2 loose batteries the terminals both pos and neg would have been at the top and easier to solder the ends
