New Battery

Bought two new batteries for my 24 v terrova a month ago. Used em 4 or 5 times. Ran the crap out of em on Grenada and can't get my onboard charger to recognize one battery is hooked up. Took out of boat and back to shop I bought it from. He put on charger from 9:30 til 1:30 and I took home and hooked back to on board charger. Looked this morning to find a still solid yellow light on the charger. Switched to another bank on the problem battery to see if it may be the charger, but still only getting solid yellow light. Shop told me battery was fine, I doubt that considering the trouble I'm having. Am I wrong wanting them to replace the battery since it has a 2 yr warranty and will not charge for me?

When/if you reverse the charger to the same two batteries does the light show yellow on the other lead ?

Green blinking on the "good" battery indicating the charger is not the problem, with my limited electrical knowledge, problem battery still yellow

Did they load test the battery. About the only way to really check one.

Had a guy at advanced check it, was at 7.6 v, guy I was dealing with was lacking.... I've never killed a battery in a month

Take it back and tell you want a new one

I can be a butt sometimes and just trying to make sure I wasn't overlooking something

Don't think so, not uncommon for a new one to act up pretty quick

May just use em as core charge and get some new 31s. I got 10 hrs of life out of em Sunday but they were dead as a doornail

Heck on a core charge, full refund and use that as a credit on some new 31's.. you got bad bat-trees from the get... IMO
