Also from my experiences: HP HSTNN-C02C (398681-001) & TOSHIBA PABAS066 (PA3456U-1BRS) - Does NOT Support SMBus (possibly I2C?) So cannot check with NLBA1.
I will update this when I have more non-standard pinouts to report or ammendments to the stated pinouts.
This battery has two System Present pins numer 6 and 7 marked as CONT1, CONT2 on the Pcb. Both should be connected to ground to engage mosfets properly. If only one SP pin is connected one of the MOSFETs will be overheated or charge will not work at all.
Also pin 3 is a Thermistor, it is not System Present pin.
Another tip is to mark all available plus and minus terminals for correct current passthrough. Using only one pin is enough for communication but could be not enough for charging or discharging especially on a batteries with ribbon connectors.
This model has only eeprom memory on the PCB, there is no SMBus or I2C chip so you can't read data from it.
Hello, yes I am talking about that model of HP, the only difference is that the Li-Ion label in the corner is a different color. The model number is the same.
Do you have the pinout for this type of battery so that I can check it?
I don't normally do re-celling because trying to get into the battery pack usually causes damage to the housing, meaning I can't sell the battery pack on. Though I have seen other people do homemade recelling, including trying to make a MacBook battery using 3 iPad battery cells in series! Unsurprisingly, this didn't work, but the aforementioned iPad cells were still good.
Wow, didn't know the Toshiba had no way of reading data. I guess you couldn't even read data if connected to the laptop? Meaning that you had absolutely no way of knowing what the remaining capacity was! In the end I just broke that pack apart (along with a few others) and I now have a ton of 18650's that need testing.

Thank you for letting me know and apologies for that, I assumed that pin 3 was a system present pin from my multimeter readings. I haven't taken apart any of these battery packs as my first preference is not to disassemble, since it very rarely results in a case that can be put back together again.
In which case, please can you update the library to reflect your new information of -1D4C5 T6 T7 +9 for ASUS A32-F82.
Pinout could be submitted to database directly from Nlba1 software. So if you found a new pinout which is missing in search menu, you could submit it by yourself. The only attention should be drawn to its correctness, because database already has many wrong pinouts added by customers who not checked it properly.
Concerning revision of already available pinouts in the database, it could only be done by server administrator. Forum moderators dont have access to pinout database.

I don't really remember the exact pinout because these batteries are quite old but i remember that all of them had BQ2084 which is supported by NLBA reset licence.
You can find clock & data pins easily following this tutorial

There is a way to read data when battery is inserted in laptop using software like Batteryinfoview, Aida64 etc.... but information will be limited.
There is also a solution to unlock the eeprom chip and reprogram it if necessary but this requires additional hardware (Usb Eeprom reader).
