Identifying the good cells in a dead battery and moving them to another battery, to get it working. But even the 'good' cells are well used, so will this repair stand the test of time? WARNING: Repairing lithium power tool batteries is potentially DANGEROUS. Wear eye protection, do not short or overheat cells. If in doubt - buy new batteries.

18 volt ryobi battery rebuild MK-I success with old laptop battery cells
 
06:24
I said i would rebuild and so i did, the ryobi 18v lithium battery i showed im my last video. The end result is a quality just as good as the laptop battery i had (doesnt last long) but overall it was a success. The model of the battery is P104. I think it is the first generation of lithium batteries from ryobi. 46 what hours, not 72 wh. I will be attempting to rebuild the 40 volt ryobi battery you see in the end of the video as well.

I got sick of staring at all these 18v Ryobi tools lying around the shop without batteries to power them and found a cheap solution to bring them back into use. As mentioned part-way through the video, these puppies can be used to weld, be very careful messing with high capacity power packs. https://www.youtube.com/watch?v=bABCvucGATc

How to revive a Ryobi 18 volt lithium battery. Quick and easy
 
04:21
Don't buy new battery just Restore revive 18-volt lithium battery P102 by drilling two holes on a battery one on each side of the battery pack and boosting the energy back to the power source with some kind of power supply to reboost using two pieces of wire about a foot length placing the wires into positive to positive and negative to negative . If this Method doesn't work for you I have a completely different solution for that just let me know with a message and I'll make a new video for you. Guaranteed the new Method .

Nicd Battery Pack Rebuild Total cost at time of rebuild was $22.54 to rebuild the entire 14.4V Pack with better than original batteries. Here are soldering tabs:http://amzn.to/2dMfqFX Here are great cells with tabs pre installed: http://amzn.to/2ld99IF 16 cells= 19.2 v packs 15 cells=18volt packs 12 cells =14.4volt packs 10 cells = 12volt packs If you need a soldering iron: http://amzn.to/2ldgPuD This is my favorite 140watt: http://amzn.to/2kAYbK1 "Sub C" are approx 1-11/16" or 43.1mm tall "4/5 Sub C" are approx 1-5/16" or 33.4mm tall Both are approx 7/8" or 23mm round the same as a C size battery UPGRADING TO LITHIUM: https://youtu.be/q2eaKCzf04c Combining Packs: I didn't want to go too much into the theory of load testing the cells. You can charge the pack and let it sit for a few days/week. Then put a flash light 3v bulb onto a individual cell and measure the voltage as the bulb is attached. You'll be able to determine the strong cells vs the weak. The good cells should stay around 1.3 volts or more. You'll see some drop right under a volt immediately(those are really bad). Letting it sit for a while shows you the cells with high self discharge rates.

Cordless drill battery pack DIY upgrade / rebuild - sealed, no screws

Let me guess, your cordless drill is driving you nuts, right? The battery doesn't hold the charge as it used to, it doesn't have enough power to screw in even the tiniest screws. And new one will cost you a fortune. Even new battery costs a little bit too much. Second hand drill will most likely have the same problem. Well, that's pretty much the story here. I like my stuff to be cheap, second hand, but I like to make the most of it as well, so I upgraded my old used up battery.

Recovering Ryobi + Plus Li-Ion Smart battery with a power supply

Recovering not charging Ryobi One + Plus Li-Ion battery by charging it with a power supply using maximum of 4.2 volts per each of its 5 Samsung 18650 battery cell pairs that can be found inside once 5 security screws are removed from the top battery cover. Also by taking it apart you will see why lithium smart batteries cost more than similar Ni-Cd battery packs as they have the smart circuit tree that is complex and unfortunately not easy to fix repair and although giving a convenient way of checking battery charge level it gives away reliability due to its complex and heat sensitive nature.

Rebuild Worx 18v Lithium Battery Pack with Sunstone CD Welder and Weld Head
 
02:40
Here we have a Worx brand battery that powers various lawn care tools. It is an 18v pack, meaning it has five Lithium Ion batteries, that are rated at 3.7 volts each. Three of the five batteries have failed (0 volts), one had 0.7volts, and the last battery was healthy at 3.6 volts. Needless to say, this battery did not work. We pulled it apart, and replaced all five batteries with more robust, 2600 mah Lithium ion cells. It comes standard with 1300 mah cells. We doubled the capacity of the cells. We welded new tabs on, where applicable, and reused the main tabs on the last positive and negative terminals. Lithium cells typically take less energy to weld a tab on them, that a regular Ni-CD or Ni-MH, as the terminal is thinner. Watch this video, and if you want to start rebuilding battery packs, give us a call and we can get a Sunstone Engineering welder in your hands! Let us know if you have any questions.

How to charge A DEAD 18V Lithium Battery Pack!
 
05:08
I just wanted to make a quick video to show how I was able to get my 18V Ryobi cordless drill batteries to take a charge again. This is actually the second battery I did. Well the 2 batteries that came with the tool kit stopped taking a charge and just blinking red in the "smart charger" after only about a month. I was not shocked (pun intended) since they felt a bit lighter than the more expensive ones I already had from this manufacturer. I don't know if the 12V DC I used is the only method, but it worked twice in a row for me. I said 2 seconds in the video, but I don't know if it was even that long. If it didn't work the first time I would have gone back and tapped the positive for a few more seconds. In summary, both batteries that I fixed have now been fully cycled multiple times in the charger and have worked like new in all my tools. After I let the one charge fully that is shown in the video I put it in the flashlight to test it and ended up turning it off after 3hrs. Bottom line, I couldn't be happier that it worked and saved a bunch of money by not having to get new batteries. Lastly, if my batteries had been old and well used I would not have tried this due to the dangers of lithium batteries, I would have just gotten new ones. In my case, I knew they were only a month or so old and had somehow dropped below the "smart charger" built-in voltage threshold, which I think is around 3V for most lithium chargers. That is all I believe really happened, is that I simply raised the voltage just enough so that the smart charger would recognize the battery and allow it to receive a charge. The output specs on the adapter were: 12VDC, 500mA I needed a T-10 security bit to remove the screws for the battery case.

Decided to use battery holder for 3x 18650 elements to avoid spot welding of batteries. Added BMS to control charge/ discharge, so original charger cam be used for charging. Battery pack case was too small to fit battery holder with BMS, so front of case was cut off and then battery holder secured with electrical tape - not nicest solution but works well.

Ryobi 40 Volt battery will not cahrge - Alternate Charging Method
 
01:16
Frustrated with 2 warranty repairs is SIX months and not willing to spend $100 on a new battery that will probably FAIL again, I developed this method to allow the RECHARGING of a Ryobi 40 Volt Li battery (not in the Ryobi charger) for less than $15.oo. I have only tried this on one battery, but the principals are sound. With so many 40 Volt Li batteries FAILING on Ryobi equipment, my guess is that the logic used to control the charging is flawed (eg., charge the 40 Volt battery in a Ryobi charger, do lawn work for an hour, until the battery is exhausted, place in charger-after it cools down-and get the kiss of death Red/Green flashing lights. I even put mine in the frige for a few hours, STILL Defective, waited days, STILL defective, put on the charger for days, STILL Defective) I put my 2nd battery in the charger after use, CHARGES up completely. BOTH worked at first, now, for NO reason, AGAIN, ONE is defective! Hope this helps. Please be careful.

DIY How to revive/fix/rejuvenate/Repair/ recharge a bad dead rechargeable NiCd battery for cordless
 
02:32
Only works on NiCd batteries. Do not try on other battery types. In this video I take an old 18V NiCd battery that has not been used for 4 years, because it wouldn't hold a charge. My Ryobi battery that I used on all my cordless tools (circular saw, drill, reciprocating saw, vacuum, rotary saw, sander, and flashligh). You will need an alternate source that is around twice the voltage of the battery you want to rejuvenate. I need 36 volts and was only able to combine the 3 batteries I had to make 45V. I could have drained some charge down, but I decided to just use the 45V and it did the job. I connected my batteries in a series, but you can use any source that is about 36v. It is important that you follow these steps to get proper results. If you are not able to recharge after this you most likely have a dead cell. 1st - Fully drain your battery, so it shows no voltage on the meter. 2nd - Connect your batteries in a series. 3rd - Take the negative lead of your series and attach it to the negative terminal of your dead battery (I just taped it into place) 4th - take the positive lead from the series and quickly and repetitively tap it to the positive terminal of the dead battery for 5-7 seconds. 5th - Check current with the multimeter to make sure your dead battery accepted the charge. If it did not wait 5-10 minutes and try again, before determining you have another problem, just in case you made a mistake in the process the first time. 6th - wait 10-15 minutes before attempting to charge. 7th - Fully charge battery and test test on multimeter. 8th - Enjoy your newly rejuvenated battery This will work on most all NiCd batteries. This is a must for anyone with a cordless drill. Save your drill for years! Works for Dewalt, Sears, Craftsman, Ryobi, Porter-cable, Black & Decker, Kawasaki, Makita, Bosch, Milwaukee, Rigid, Panasonic, Ridgid, Hitachi, Snap-On, Cordless Max, Master Mechanic, Drill Master, and any other type of drill with a NiCd battery.

Ryobi 40v battery charging problem /  FIX
 
03:26
I spent a lot of time trying to figure out the charging problem with my Ryobi 40 volt Lithium batteries. They were only 2 years old... Flashing red and green light on the charger.... both of them, and neither would charge. I didn't have the original receipt from Home Depot where I purchased them... So I spent countless hours trying to get them to charge so I could mow my lawn. I finally just went to Home Depot and bought a third one for $100 (ouch) so I could get the job done. Later on I found out that Ryobi has a 3 year warranty on the battery and charger.... and you DO NOT NEED the receipt in order to get them to replace the charger and/or the battery for FREE if your still in the 3 year replacement window.

Rebuilding an 18 volt DeWalt Battery Pack
 
03:44
Does your battery no longer hold a charge? Do you want to save a bit of money? I did. Plus, I wanted to see how hard it was to rebuild my own battery pack. It's not hard. I show you how I did it. I used 15 Sub-C sized Ni-Cd batteries to rebuild my 18 volt Dewalt XRP battery pack. It required removing the 6 Torx screws, opening the pack, removing the contacts from the cells, soldering the cells together, and putting it all back together. This is not something I would do again. I will just pay a bit more for the pre-assembled cells and install them rather than resolder everything. It will save a ton of time, and my time is valuable. https://www.amazon.com/gp/product/B009WXZMIG/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1
