Late reply here. I harvested a used battery cell from an HP laptop. I made sure the manufacturer was ATL, since they are the best cells.Hello, It seems you know what you're doing, when it's about batteries...
I just replaced mine, after finding a model that seems to be manufactured on purpose:

But, the problem is, that the original one is 4.35V/cell maximum (nominal 3.8v), whereas of course, the replacement is the more usual 4.2V/cell.
So the R5 software is unable to identify 4.2v as 100% ; once charge stops the gauge is at 92-93%, and the worst; when it reaches 1 to 3% and stops by itself the cell is still at around 3.6VSo I'm unable to take advantage of the whole capacity of this new cell, even if I do not trust the 4500mAh figure that's written on it
I tried to do one full charge-discharge cycle so far, in order to "calibrate" the android gauge, with no success...
Any advice ?
For those who have changed their battery themselves with aftermarket cells; do you have this kind of issue ?
When I put the battery in it was at ~3.7V, maybe I should charge it fully then, disconnect/reconnect it ?
Maybe a factory reset would clear the old values in Android ?
Thank you in advance...
The battery you purchased seems like it is limited by the BMS the battery is supplied with. I recycled the original BMS from the old R5 battery, hence no issues.
