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...
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
@@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
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
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....

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
@@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

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
