2 Minutes - .2C Recharge




Beginning of .2C Recharge Test:


For this test 12.100V was also used as the cut off voltage after a full 100% recharge. The battery spent 32 hours of float at 13.4V and then had a 24 hour resting period. The battery delivered -48.33Ah or just about where it had on the previous test which ended at -48.54Ah.


As we can see in this image at 2 minutes the .2C charge rate only has the battery to 13.1V vs. 13.6V at a .4C charge rate. The voltage is climbing slower in bulk at .2C than it did at .4C.
