I have a completely dead battery from HP. I opened it and it turned out that the links are ok. I still charged them with the IMAX B6 charger. After connecting the battery to the laptop, it does not load and shows that it is discharged and the HP Battery Check software to change the battery....

Hello. ATTENTION! - the wrong link can explode. Eliminate the damaged link or the one dropped below the critical one (the battery was left unused for a long time and unused), now each cell should be checked and recharged. Do you have to reach all the links? As it is, you need to solder each cell and see if it can be recharged. Used for landing cells with security modules, eg. Battery charger Li-ion 1A TP4056 USB micro

I have access and I have loaded it with 2 connected in parallel. The voltage at the output of all cells (3 cells after 2 cells) gives a voltage of 11.9v IMG_201806...615[1].jpg Download (2.79 MB)

Kiss39, the author wrote that the links are working? You do not have to disconnect and check. Probably the battery has reached the limit of the number of charges and orders it to be replaced. You can read the batch and save it back after modification. There was a large subject somewhere on the electrode, including batches and a simple diagram for reading the memory through the battery connectors.

I have a completely dead battery from HP.
I opened it and it turned out that the links are ok. I still charged them with the IMAX B6 charger.
After connecting the battery to the laptop, it does not load and shows that it is discharged and the HP Battery Check software to change the battery.
Probably blocked electronics.
Is it possible to unlock somehow? It is worth having fun?
