Life batteries

[Mike Cathey]

I need some battery gurus input. I recently got a couple of 1800 life rec. batteries. After charging on a balancing charger one battery tested at 97% across all three cells. The other battery tested 97% on 2 cells and 84% on the third. Does this mean it is a bad cell?

Mike,

Run the mismatched pack through a balance cycle to get the cells equal, then cycle the pack a couple times on the charger to make sure the cells stay close on voltage.
