I've had to exchange a few batteries (H7) at Costco lately... the most recent ones display unusual behavior on my charger, and I was wondering if they're making them differently or whether these are defective. Normally, my charger (Motomaster 75/12/2 A unit) starts with the meter on a lower percentage and slowly works its way to the green, whereupon the "full charge" light comes on and stays on.... on the newer batteries, it then jumps back down to a partial charge reading, and works its way to full, and repeats ad nauseam... if I go to the 12 A charge setting, it just goes wild...
Are these newer batteries sulfated? I don't want to go back and exchange once again... (BTW: one of these newer batteries had trouble starting one of our cars at minus 10, whereas the older battery had no problem at minus 20...
Thanks,
Yuri
