Hybrid Battery Reconditioning The Original 2009 battery

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
5min wait
Charge rate 3.0amps
Discharge rate 1.0amps

Click to expand...

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

almost complete charging up the Cells going to deep cycle them to try and extract more power out of them
only had one cell that expanded slightly by 3mm already returned to normal
