If this battery is for a RV you really need a deep cycle battery for longevity and more sustained power available. Starting batteries are designed for short bursts of energy.
Testing my 2 24DC's took out of camper checked water OK, charged for 3 days left off charger for 24 hours. Voltage shows fine but the capacity shows 40% or less
I can't say I'm impressed with the battery. Especially when they don't label them completely to industry standards!. I purchased camper used and seller installed two cheapos.
