Thank you so very much for getting to the point! So many videos out there where people want to talk for 20 minutes before they get to the point of the video... You did a great job and I'm very thankful for this video have a great day!
Adapters like that are not usually accurate enough to use with lithium cells. The output voltage can be substantially above the listed ouitput voltage even under load, and as the lithium cell charges, the voltage output will increase with the reduced load on the adapter, and there is real potential for explosion/fire with unprotected cells, or just ending up with unrecoverably damaged lithium cells. I've seen "9VDC" adapters with an open circuit voltage output of almost 15VDC, and "12VDC" adapters with o.c. output of almost 21Volts. You need to be very careful in choosing your adapater and verify the cell protections when making these kinds of substitutions.
It might be worth telling people that you can get cheapo £10 chargers purpose built for charging that type of battery on EBAY and they are MUCH SAFER as they will charge till full and then STOP CHARGING which keeps battery life better and prevents risk of fire. Your method is good for kickstarting a dead battery for sure... but once you know your in business buy the equivalent charger... else your going to kill that battery.
ghettohillbilly1 Even though a lot of batteries these days have protection circuitry built-in, please be very careful doing this. You're getting away with it... but as you rightly pointed out there is no charge regulation which could result in failure of the battery. That said, if you do this with LiPo cells, you are asking for serious trouble.
exactly what I was thinking mate, incredibly dangerous,!! Connecting old mains chargers directly to lithium batteries obviously does work as long as the output is near enough what the battery needs to charge, but without the charge safety circuitry how does the battery know when to stop charging, Once lithium batteries blow there's no stopping them, very very dangerous !!
I wish you would show us newbies how you stripped the wires, put the ends on , and even tested it to begin with so we could do the whole thing ourselves ! Bummer . I know you Assumed we all know how to do this. As a gal who grew up when women didn’t do these things, I’m trying to learn my own repairs ! Thanks anyway.😯
i think i used scissors to strip the wire, i didnt put ends on, my only real test was to hook it up, leave it on for a couple mins and boom camera came on
Cool stuff, Only on my 2nd camera on thankfully they've used triple a or double a batteries, bad part about it is they use triple or double a batteries lol. New camera seems to sip on batteries whereas my old one drank'em down.
7.5v isn’t enough for the li-ion battery. It’s a 2s battery and it has two 3.6v cells. Fully charged, those cells have a voltage of 4.2v. You should use 8.4 to fully charge it.
I’ve made an e-bike battery and drill battery with li-ion cells. I also salvage li-ion cells from laptop batteries,since I live above a pc repair shop. I think I know all there is to know.
If you’re scared, use 8.3v! Also, if you’re using one of those power supplies with the round plug, test it with a multimeter. Those power supplies always output a higher voltage than advertised.
I thought that , too, but that won't cut muster: two days ago I needed one of my drills charged full power for a busy project (after much aggravation I had finally gotten the thing working great with a battery from a jump box, it even had a built in charge plug and fit perfectly to the bottom of my B&D drill). I put it charging on a 30min timer while I picked up some tools (the charger, a 12V wall wart, was the same voltage as the battery. Not the original charger but how can a 12V charger OVERCHARGE a 12V battery?) Minutes into charging I heard a strange HISS and went looking for the source. The accrid chemical smell prompted me to pick up the drill, unplug it and hurriedly place it in the garage, on the floor. I'd barely gotten back to the kitchen when my dogs started barking in the direction of the garage, the insistent BEEEEP of the smoke alarm sent me panicking back to find a rather large fire featuring badly stinking and obviously toxic smoke: the battery had exploded. I was fortunate it didn't blow when I picked it up the first time and smelled it, just as im fortunate our home didn't burn down. As for what could have happened to the woman that I love so much (who was in the room when the HISS happened), I can't bring myself to consider that It's important to note that I'm a certified computer electronics technician, I'm no amateur.
I have a 7.5v nickel metal hydride battery, kit number HNN9010A for a Motorola HT750 2 way radio. I don't have the charger for it and wanted to try what you're doing so I'll know if it works or not before buying one. It has 4 copper looking tabs at the bottom back side of battery that connect to tabs in the charger and 6 on the inside that make contact to the radio..I can't figure out which ones are positive and negative. Any idea what I could do?
I have two mobiles one has 1700mah battery and other has 2100mah battery. Can I charge 2100mah battery from the mobile which has 1750 mah battery by connecting the pins through wires. Will it work.
Would this work running the wires to the camera to power it up? I am trying to get some footage off an ole mini DV but can’t without power? Ps you sound like a fellow down Easter?🇨🇦
Yes, you can power a camera directly off a power supply as long as you have the correct power supply voltage and connect it using the correct polarity. The power supply voltage would be the same voltage as what's shown on your battery pack. Caution -- If you connect the wires backwards using the wrong polarity, you most likely will damage the camera. Your safest bet would be to look on Ebay for a used charger that works with your model camera. Another safe way would be to get the model number off the actual battery pack and then look on Ebay and find a charger that works with your particular battery. Such chargers are usually only a few dollars on Ebay.
Good idea but you possibly could find a power adapter for the camera and while it's plugged in attach the battery with the camera off - may charge battery like mine does - Cheers!
Just burnt a hole in my camcorder battery after trying this XD fyi dont use a higher amp outlet than you need. at least not without a voltage regulator
Also how to avoid ads! Step 1. Try not to get an ad. Step 2. Well if that didnt work and you get an ad just close the vid and reopen it repeat if ads continue. Ps. I think that you should only do it on long ads
No it will drain the battery back to 5 volt..see it as 2 buckets of water 1 has 7.2 liters of water and 1 is 5 liters of water so the one with higher amount of water will go the lesser amount of water so they will balance each other out.
i can try, if its not charging it probably got too low and now the smart charger wont read that its there because the voltage is too low, if there is a way to manually charge the batteries,even a little bit it should bring it back up enough so the smart charger will read it again

Thank you for a great clip. I used it to get a Makita cordless drill battery charged and it worked a treat!

I like home boys style for real. He's about his business thanks
Did it with my canon hv20 thank god I got it to boot up thank you very much for this method
That is very helpful! Thank you sir!!
Thanks for posting this bro, just wanted to be sure before I blew my arm off or some shit!
no prob
How do you tell the difference in a negative and the positive side on the battery
@@bettyspurlock4752 should have a + or -
That is a really good thing to know. I thank you for making this video.
Negative wires usually have a grey - - - - color line on it that's how you know which is ((positive & Negative)) ...

this is a last chance attempt in a worse case scenario
Going to try this when Have time. wondering if you felt the battery at that one hr. point to get a handle on , How hot is over charging.
Hi when the battery is very warm and not cold then it means it’s getting power and may be over charging hope this helps

@@masterzz57 they're supposed to output higher if there's no load on them.
You can plug the charger into a timer and set the timer to stop power in 1 hour!
Brilliant
They sell them at walmart for like 3 dollars

no you need 14.4 or more
will this work with lithium batteries?
no
Awesome dude 😎🤘👍
As an electrician one term I can teach smooth is hot rigid I’d not with this type of wire

Hi, why is your name surrounded by a blue rounded box?
Ganil you highlighted it somehow?
Yes after a few days I got the same blue rounded box in all the comments in my channel.

Can you charge a DeWalt battery like that 20 volt with a 18 volt adapter
no, the adapterr needs higher voltage than the battery
How do i know what cable is positive and negative?
test with meter
white line on 1 black chord is pos.
B
Wire with lines are positive and ones with out them are negative
Good idea but you possibly could find a power adapter for the camera and while it's plugged in attach the battery with the camera off - may charge battery like mine does - Cheers!
if i had the proper power adapter i obviously wouldnt have to do this, its the point of the video lol
I love it!!!!!
Does this work on 18650?
Thanks man! Plus I have the EXACT same camera
glad i can help
ALL DC POWER SUPPLIES ACTUALLY PUT OUT ABOUT 1.7 VOLTS OR MORE THAN THEY ARE RATED AT. BUT STILL THE ANSWER IS NO 5V ISNT ENOUGH TO CHARGE IT.
exactly

Oof
I guess it does make sense that it would work, how much is a new charger for the camera?
i think they are about $10-$20 on ebay

sir how to charge SB -L11OA battery
Also how to avoid ads!
Step 1. Try not to get an ad.

will 3.7 v work ?
if 3.7v is more voltage than what you are trying to charge
no.
can u do a canon A2400
should work
Just put the wires on the camera
Would a 7 .2 volt battery charge with a 5.0 volt charger?
no, charger voltage has to e higher than battery voltage
