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?
Hello. I have an X541SC laptop and the battery died. It lasted 2-3 hours, but I can no longer run the laptop with it. When I took it out and measured + and -, there is no voltage. I told myself it was dead. I took another second hand, but i did not measure it before taking it. I just took it and put it on the laptop, but it's the same case. When I measured it, again there is no voltage of + and -, but the batteries themselves on both sides give 11-12 volts. Does anyone have any idea if this is a dead board / battery processor, or for some reason there is a protection that has turned on and stopped the output voltage? I found this on the internet: Some batteries are equipped with a solid-state switch that is normally in the “off” position and no voltage is present at the battery terminals. Connecting the switch terminal to ground or pulling it up often turns the battery on. If this does not work, the pack may need a code for activation. Battery manufacturers keep these proprietary codes a well-guarded secret to which even service personnel have no access.
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
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..
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
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.
Hocam burada pil in + kutbunu nereye degdiriyoruz acaba ? Benim de piller şarjlı durumda batarya %98 gösteriyor ama şarj olmuyor. Sizin yaptığınız gibi bms resetlemem lazım sanirsam
Selam Hocam, burada pil in + kutbunu bir kablo yardımıyla bataryanin kartinin + sina deydiriyoruz. Olmazsa aynisini pilin - kutbuyla ve kartin - tarainlan dene.
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
O cip icin CP2112 diye kucuk bitane board var onunlan resetleme yapabilirsin, CP2112 board'la nasıl resetlenir diye yakımda bitane video yapmayı düşünüyorum.
@@engineersgameplay1063 You have to pry open the pack. Use a glove in the hand gripping the pack. One of the three pairs is dying...once open, the multitester will show you all the pairs with the same voltage...but the truth is that a dying pair will not show average voltage, but the better cell "rule"...4,2 or so volts on each pair. Once pry opened the pack, you have to charge, with + to + and - to - charger to pack polarity...direct from the charger, not passing through the bms. After 20-30 minutes, with a bare hand, you will feel an overheated cell or pair of cells...also you can use a digital medical thermometer, but those usually measure just to 113 ºF/45 ºC, but still serve for this. If you have a pair of new (or used in good shape) 18650 cells, you have to connect them in parallel, before cutting the pair in bad shape, the idea is to "cheat" the bms circuit and never having it without voltage, a fraction of a second and you`ll have to trick the bms for a reborn. All of this also can be done in a laptop shop, but if they charge $30...maybe can be better to buy a new one pack for $50...or maybe they rent tools and space for some of $10/hour (plus tech advice :) ). In the 6th paragraph there is info about no voltage in the bms circuit: batteryuniversity.com/article/bu-911-how-to-repair-a-laptop-battery Regards.
Buenos días me parece interesante yo he cambiado las baterías que eran de 2000 mAh y le he puesto cuatro baterías de 3400 miliamperios. No me ha dado resultado. Me gustaría comentarte algo personalmente si es posible por algún medio
Tienes que resetear el chip de conteos de cargas que se encuentra soldado en la placa de la batería con una EEPROM o un re programador de chips para resetear el conteo de ciclos de carga
Мне жаль. Это может быть не так. Возможно потребуется программировать саму плату) BMS. программирование может быть выполнено с помощью CP2112. Как именно происходит программирование, я недавно сделаю видео, там вы сможете увидеть.
Yeah right, the maximum voltage is 12.6, yet you show 14.33 on your meter. Just how did you accomplish that? Cutoff voltage is 4.2, so in a series of 3, you would only get 12.6 volts. It even says on the battery pack itself 11.1 volts. I guess you think it's funny to have people try this or something, I'm pretty sure that meter is connected to a different set of batteries. The nominal voltage is 3.6 for 18650 batteries, so a series of 4 would give you something like what is shown on your meter.

Thank you, my friend. It worked
Muchas gracias me sirvió.
I tried with my Lenovo g500s battery pack BMS,but still out volts are not coming from battery..please advised
Thank you very much. It is very helpful.
Excelente
Nice.... Dell latitude it's ok, the short circuit made a bypass in board.... Thanks bro
Estupendo amigo! Muchas gracias!
Tenías la batería cargada al 100% ? A mi no me ha funcionado
👍

I’m not the only one that noticed you disconnected the multi tester terminal before the test...impostor!
i guess so he disconnect the multimeter

Em 2:35 ele conecta novamente. Para dizer que funcionou.

Thanks! It works, indeed!
goodjob
Thank you sir.
I have a question. You show how to reset the 3 series BMS, how about 4 series laptop BMS sir?
I tried same way, but it doesn't solved.
Good

I changed cells and reset it by giving direct jumber 12 v. It didn't work. laptop is 3rd gen. i5

this worked on a dell 1745/47 11.1 battery pack..
Can i reset sony vaio laptop with the same method? Eeprom chip R2J240
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
this does not work with every balancer
То что напряжение появилось на контактах, это не означает что аккумулятор будет заряжаться.
No es que esté cargada, al hacer ese toque se activa la salida del módulo hacia la laptop....y enseguida se pone a cargar....
el problema es que a veces para destaprla la carcasa de la bateria se rompe, en si que lo dificil es volverla a armar
Tienes mucha razón. Pero después de abrir algunas cajas se usa.
Which is what don’t understand all laptops 💻 not same so how

Are the batteries charged to at least 3.7 volts
selam hocam, BQ40320 içinde çözüm var mı? Onda olmuyor. Bu dell laptoplarda olan TI ın çipi. Datasheetide yok. Şirkete özelmiymiş neymiş.

Hocam dell laptop bq30423 çipi nasıl resetlenir bu yöntem bende işe yaramadı
what exactly are you resetting?
cycle count?
The cycle counter sends an "off" signal to the BMS when reaching 600 cycles...but batteries still have 80% of capacity.
@@TheFireControl plz explain more.. my battery shut off in 10 minutes.. all cells have full voltages

So you mean it will come back agin unless you do it your way
After some minutes laptop shuts off and relock again 😢
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
BIOS locked the battery. You need to reprogram de BMS

Not work
El video esta interesante pero no muestras con detalle lo que haces

Bro apko battery Repair kerna ata hai ?
Wahaha, he just unplug one of the terminals of the voltmeter when he tests the output
No such thing
next how to reset camera auto focus ..
Это не ресет, это пинок
Resetlendiğine dair bir işaret göremedik
Resetlemeden önce, çıkıs 0v. Ama kablo ile kısa devre yaptığımda,çıkış 14,5v mevcut.
You unplugged the cable of tester before to test, come on!!! 😒
masuk juga nih??
cat got your tongue?
Plz add ur voice
So? ........

Why don't speak , why no sub for making clear ?
Тестор не рабочий ))должно быть 12.6 .v
3s = 12.6V not 14.44V your multimetr is not good
Speaking might be helpful. Dont be skert!
This is Acer battery Wich make sanyo Chip and software for example Bq 803xx and ba80xxx and some time bq20xxx series please take down this fake video
Cheater. Of course if you disconnect multimeter it would not show anything. Dislike.
