Hybrid Battery Reconditioning The Original 2009 battery

[BG1988]

I pulled the battery Didn't found any bad modules with low voltage..

Right now i'm cycling the modules individually

*Note: module #2 and #3 was charged in serial and rose in voltage so capacity on results may differ slightly.
(testing settings on how to work the charger) asetek symbol was added.


Update: looks like the battery had been messed with at some point in the past because of non oem markings only doing discharge (mAh)

initial Voltages shown below.

Charger settings
Discharge/Charge cycle
6.0V minimum voltage
Max voltage 9v

the lowest cell so far was 7.5v to 6volt = 98mAh 1.50% of the original cell capacity of 6500mAh LOL

I have aggressively been attacking that cell with cycling it's at 900mah now..

the weirdest thing is the cells are not even getting warm or hot that is a good sign of low internal resistance
