I’m not the only one that noticed you disconnected the multi tester terminal before the test...impostor!

[tiago]

Nice.... Dell latitude it's ok, the short circuit made a bypass in board.... Thanks bro

Your 3s pack is seriuusly charged to 14.3V, you are aware that a lithium cell charged more than 4.2v is explosive witch is probably why your bms tripped

То что напряжение появилось на контактах, это не означает что аккумулятор будет заряжаться.

[bayuhariyansyahlubis]

Thank you sir.
I have a question. You show how to reset the 3 series BMS, how about 4 series laptop BMS sir?

Dell D600 battery (C1295) With a jumper between Ground and the SYS PRESENT pin I can measure voltage and discharge the battery using a R/C charger /discharger. However I can not charge at the out most pins. No current flow goes into the battery.

If I put the battery back in the laptop it will charge it full again. Would you know if I need another jumper to allow the battery to accept charging?

this actually worked but you need to drain the battery best way for me was connect a 12 volt pc fan until it drain out to 0 it took a few minutes the fan will not slow down just stop totally after a few minute then reseal the battery and connect it to your the pc and start it up with the plug charge connected

once windows starts you should see the battery charging from 0% to 100% like normal

Solo funciona en algunos casos, en mi caso no.. pero ya conectando en el equipo Windows me decia que no detectaba la bateria asique supongo que ya tiene problema en la mother de la bateria o bms..

[davidbolha]

In actuality you need specialised hardware (i.e. EV2300/EV2400) with software (Smart Battery Workshop or Battery EEPROM Works) to really reset a laptop battery. Specifically the BQXXXX IC that is located on the PCB board - to which the 3 pairs of 18650 cells are connected to. 😑😕😒

I have an assembled/saved playlist with videos on this topic on my channel.

nu merge atata timp cat a trecut termenul de incarcari si descarcari ale baterie degeaba schimbi celulele pentru ca atunci cand dai sa resetezi bms nu mai merge din contra iti distruge celulele de tot si risti sa iti explodeze in fata

[edmo]

el problema es que a veces para destaprla la carcasa de la bateria se rompe, en si que lo dificil es volverla a armar

After some minutes laptop shuts off and relock again 😢

Bro, I have rebuilt my Lenovo Laptop battery with 4 new cells but Error shows "0% plugged in not charging", please help me what problem?
Old cell: 3.7v/2200 mAh, Sanyo
New cell: 3.7v/2500 mAH, Samsung

[lotharmayring]

this does not work with every balancer

[توكلعلىالله-قم]

I brought a board without batteries and added batteries to it. I did the same as you did and it didn't work for me, what is the reason? Please Help

[the.real.ipatch]

what exactly are you resetting?

cycle count?

[abod]

How is it 14V ?
Lets say every 2 battery pack is 4v thats 12
My battery only gives 12v amd goes down to 11.5 when on load

[stigonutube]

this worked on a dell 1745/47 11.1 battery pack..
