Yep, if one gets too low hooking a good battery in parallel fools the charger and can bring one back. They're great batteries and will last if kept on a tender but they fail "different" at least mine did. Had me scratching my head for a while....

My old battery charger wasn't fooled by jumping with a "good" battery, my new battery charger has a selector switch and you can tell it "AGM" and it will"push" harder and run the max volts higher / longer and it works well. I thinkit was 75 bucks but imho it was money well spent.
