Good step by step battery rebuild video. The pin breakout notes are a good, useful addition.
For anyone trying to activate the BMS on a Trimble 31CR19/66 battery module, (for a Trimble GeoExplorer), connecting the battery 12+V terminal to Pin 6/ +V on the battery module, it does not work. (Maybe someone else trying this on this Trimble module will be saved some time and frustration.)
At the start, the three Li+ batteries inside the module measured 1.5V each, but the BMS had apparently shut the charging down completely, and across Pins 6 (+) and 8 (-) were 0V. (These pins are labeled on the module.) When connecting to the Trimble power adapter, the module charging light showed green almost immediately, (no amber at all); potential across Pins 6 & 8 = 12.5V; potential across Pins 5 & 8 = 15V; unplugging the power adapter, the potential between Pins 6 & 8 and 5 & 8 returned to 0V. Each cell was then charged to 4V one at a time while still connected to the module circuitry. Pressing the PUSH for battery module status showed almost full charge; potential across Pins 6 & 8 = 0V. Briefly connecting from the Li+ battery 12+ to Pin 8 did not appear to reset anything. Sometime before this, when plugging in the power adapter, the module power light would briefly show amber and then change quickly to constant green, but not charging.
Super, thanks a lot. I tried it with an old Asus EEEPC-Battery and it worked. Great. For security reasons, I used a 20 Ohm Resistor instead of short-curcuiting...
Great 👍
I've tried to find a way to RESET the laptop batteries for a LONG time. I just did FIVE of them. This is a GREAT HACK for me. Thank you very much.
it’s a method of reset laptop bms, I've explain that this method not work all bms, thanks.
@@DreamFinder yes this method not working for my BMS 6 cell battery
Hola. El conjunto de baterias debe estar cargado al 100%? A mi no me ha funcionado. Alguna otra solución por favor? Gracias
Yes it is the correct way to change the batteries but the reset method is wrong and won't do any good unless the IC on the BMS is reset by ic reset tool because the ic holds information up until the battery cells dies and that information can only be reset by using a reset tool and a program
More information?? Please my battery cells showing 3.2 volts but BMS not output
@@mangalsinghbhati1 the BMS holds the information of the previous battery ...it wouldn't work if you just replace the battery...you have to have BMS IC reset tool ..which is more expensive than a brand new battery..so it's better to just replace the full battery
@@uniquedesigns4544 "ic reset tool" // Any suggestions about this tool? Can it be emulated with Arduino?
he tried his best but the laptop will not recognise this battery because after adding new cells to the battery there is a IC on the circuit which will need programming too like bios ic..after programming the ic the laptop will recognise and recharge the battery otherwise no mater how the cell are changed from the oldest to the newest with full voltages the laptop will reject it as it is the old battery
So how does one reprogram the battery pack IC then ?
@@packratswhatif.3990 need special programmer for this purpose to programme the BMS circuit of the battery pack..
Yes....your concept is correct..need to be reprogrammed.......otherwise the battery pack will not charge through the BMS chip..or...will not cutoff the power to the battery....so it's will be rescue....
No wonder none of them show that they put it back in a laptop and it works...
What if this reset method doesn't work? I have HP 4 cells battery...
I had the same problem with a Toshiba computer battery. The batteries are charged and the electrodes give 12 volts when measuring, but the output BMS It gives the value 0v. I tried the same solution you did but it did not work. Is there another way?
Best Laptop Battery repair video I have seen yet. Great work.
Thanks bro
For those BMS protected problems I guess you could include new BMS charge and discharge board inside the laptop. Windows fuel gauge won't work because there will be no comms with SIO chip but at least practically can work again.
Thank you so much for your time to answer to my post.
Three days ago I managed to resolve the problem which - en passantt - was not a matter of heat, bad connection or faulty circuitry.
Remedy had to do with uninstalling the drivers of Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery.
If you want me I can translate the few steps and send therm back to you to have them handy. Just let me know . . .
Have a nice day !

Ohh nice.
A rule for repairing litium batteries is to never use batteries of different age or capacity because they will be out of balance when they are not matching. either will the BMS shut down the battery during charge or discharge when the weakest battery reach high or low voltage. and worst case total failure. And no, it won´t be able to balance the voltage correctly if the difference is too big. sure if you would measure and match all batteries with analytic testers it might be close enough, But if you spend this much time on a battery then there is no reason not to change all the cells together and repurpose the working cells for less accurate tasks instead

but waddabout all new cells, einstein?
@@rodrigodiaz7167 If you change all cells to new equal ones you should be fine. Then it should perform like a new battery.
Einstein did not know anything about Lithium Ion batteries so in this regard I know this specific topic better than he did
@@Pulverrostmannen LMAO yeah i think some of these batteries always die once you unweld them though bc of the BMS. i wish the state banned all these battery packs and would force manufacturers to let you just put standard cells like on an old torch
I'm so full of programmed obselescence. your whole pack dies just bc one cell worth $1 died and you are forced to pay $25 for the pack and trwo 2 perfectly fine cells into the ocean. sometimes they BMS just fails for no reason even with good cells.
i tried in acer e5 laptop battery but no use it advance bms locked itself need to unlock by software
Even if it shows voltage on outputs, battery couldn't hold current normally. Only programming.

I want to charge a Dell D600 battery. In order to measure voltage I needed to ground the SYS PRESET pin. I can discharge the battery but I can not charge the battery. No current flow enters the battery. However I can charge the battery when using the laptop. Do I have to do something to one of the other pins to allow charging?
Input and output same pin, most of the bms not support
hi there are 5 pins in the dell battery
to unlock charging you have to connect the 4th pin with the ground then charging will work.
1st,2nd,3rd, pins are negative,
4th is the terminal pin to enable charging
6th is data
7th is Clock
8th and 9th are voltage + possitive.
thank you
@@hitmanyt2021 Could you please confirm the battery pin out. I have a Dell D600 laptop battery Type C1295. It has 9 pins. I looked up a chart with a picture and the pins you mentioned don't match. The pin out shows the battery with the writing on the battery facing up and the connector to the left.

Dear DREAM FINDER,
My original Qosmio X505 laptop Li-Ion battery (Model No PA3730U-1BRS) is coming to an end and I purchased a new one of the same model that is not recognized by the laptop, when clipped on. Powering on the laptop from the mains (through charger) it starts with a yellow blinking led and hovering on the battery icon (right side of task bar) shows “Battery plugged in charging. After 6 - 8 minutes it shows “Plugged in and not charging”, to end up with a “battery not recognized”. On restarting the laptop the battery icon shows “Battery not detected” with a red X on the icon.
Watching your video carefully I understood that - correct me if I am wrong - the battery should be “activated” by the factory.
So, my question, though I imagine your answer, is if I could activate/reset the BMS circuit myself, without opening the battery shell.
Constantine
Reset not required of this problems dear. It’s may heating or circuit issue or missing from the battery charging slot. First clean everything carefully and plugin.

I have my battery opened and checked but all cells were okay but still it is giving me red and white blinking indication showing that battery is low and not charging. what the problem is?
Most of the BMS not work this method
@@DreamFinder so what should to do?
I have done it.. I connect a cable from the main positive of the battery to the positive of the external connector and, it does not work. it's from a dell laptop
Ofcourse it will not work, this movie is fake. You can not switch some cells because the internal resistance is different an can get into fire. But the guy who made this video does know anything about batteries or electronics.
Very nice good job
Thank you! Cheers!

Sir mera dell ka laptop h usme mai cell Cheng kiya hu but oo battery me bms me supply Nahi show kar raha h please help me
Most of laptops battery doesn’t show output directly, company tricks maintain battery bms. So don’t worry bro. If this formula not work then u have to change or replace new one.
Interesting
Thanks
battery reset tool required
very well done
Good one
Thanks
Thanks Brothers 🎉
Welcome bro
will this work on Dell battery?
Input and output same pin, most of the bms not support this formula, but you can try.
A REAL DANGER OF FIRE!!, applying tin with the soldering iron directly on the cell and without changing the nickel, without adequate protections, if you want to have a real risk of fire in your homes, go ahead.
Thanks
My all batteries ok but no output and doing same process but still same problem
Uff.., it's a really sorrow matter my dear. Some BMS not working this process. However try this process. If it doesn't work, not a other solution. Please don't throw your old batteries, next any time you can replace damaged battery.
