Is anyone able to identify the type battery from this photo? I believe they are original factory and ready to replace after 8 years. They were probably ready last year.
I've always thought they were AGM group 31s, but can't recall why. They measure approx 13"L x 6.625" W x 8.5" H.
Right as I was debating whether to get regular GRP31s, at 105a/h each, or the new GRP31XTs, with 125a/h each, I pulled my original survey to confirm what I had. To my surprise, its says they are 4-12volt wetted lead acid batteries. They don't look like wetted batteries to me? Particularly, since they clearly say not to open them (in what appears to be German and English).
So I pulled the original brochure and it says "four 80a/h DryFit service batteries". Those are gel batteries, no? I am her second owner, so they may have been upgraded at original commissioning.
So, holy smokes, I have no idea what I have. Worse, I have no idea what the Xantrex invertor/charger is set up to do. It must not be too messed up to have gotten me this far.
The manuals, of course, are on the boat. Anyone good enough to identify these by sight?
