I believe the epoxy on the cell on the end came free allowing acid to leak whenever the battery was jostled, such as when I move the battery or if I hit a bump while driving the RV. The corrosion in the battery compartment looks like it has been leaking for awhile. When the battery is normally sealed, I don't think liquid or fumes can escape from this type battery. I checked the "Float" Voltage of my Battery Tender. It is 13.3 VDC according to my WalMart Digital Multimeter. I'll probably take the advice and go to WalMart for a new deep cycle battery. I believe those batteries are made by Johnson Controls. I also checked HD but they had no Deep Cycle Batteries.
I'll try to add a photo of the battery and cover so that NO ONE will do what I did to the battery.
That is not the same battery that was in my 2013 Sunseeker 2250 SLEC.
My battery did not have a handle and there were two caps covering three cells for each cap. The caps were positioned length wise along the center of the battery.
