What will cause an individual battery cell to reverse polarity?
The charging circuits are connected in the correct polarity but all of the cells are equally charged.
High discharge rates without allowing for a cool down period.
Correct Answer
When discharging the battery — if a cell becomesweakerthen the remaining cells the discharge current will effectively charge the weaker cell in reverse polarity.
Insufficient charging which does not bring all of the cells up to full charge.
