Re: Replacement Battery with low cell Voltages

It just seems that way. From 3V to 2.6V there is hardly a percent of capacity difference.
It translates to 0,01V difference at top end. Aka same capacity difference (a percent).

If any cellpair drops below 2.5V it kills the contactor. Even during acceleration. This is why
power bubbles disappear a mile before dead.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

Update - new battery has about 1200 miles on it and about 1-1/2 months. AH has dropped from 66.14 to 63. SOH dropped to 98%. Temp bars always mid-range, one QC, one "VLBW". At this rate, a I'll be back to my old batteries final reading of 43 AH in a little over a year.

I'd guess that as the pack balances better this will level off - but no sign yet.
2012 Leaf SL; 30,000 miles. 8 bars - Battery replaced November 1st, 2016.
4000 watts Grid-tied solar. 3000 watts (level II) off-grid solar Leaf charging capable.
