Are my batteries shot? Charging question
Hi All,
I have 2 70AH 12v batteries conected for ~140AH @ 12v. I have a 10A charger on them overnight and it still says about 4A going in at 15v . I'm thinking these batteries are no longer taking a charge. One battery was half empty when I got the rig so I filled it with distilled water and charged it. Both batteries on resting read about 12.8v which indicates they are charged. Hooking up the charger to top them off I would think the amps would drop down to a trickle in a short time, couple hours? The charge started at about 8A and has tapered down to about 4A and not falling any lower. What are your thoughts?
