VRLA Battery 12V 80AH | Dimension: 331x174x214x219mm
GRANKIA FG80-12 valve regulated rechargeable 12v rv battery 80ah is constructed with Absorbed Glass Mat technology allowing for a low-maintenance and spill proof battery.
Flame Retardant ABS case and cover to UL 94 V-O for superior performance. Proven VRLA Absorbent Glass Mat (AGM) Technology that guarantees safe operation without maintenance and “non-restricted article” status for transportation.
Valve regulated rechargeable 12v rv battery 80ah charges up to two times faster than conventional alternatives. No need for checking Electrolyte level and topping throughout its life. Sealed construction Ensures no leakage of Electrolyte from Terminal or casing.
For most travel trailers, you have two choices. The amp hours (Ah) of these batteries can vary from 50Ah to 400Ah. For pull-behind campers, you’ll most likely need 12V 80Ah or 12V 100Ah batteries. If you choose to use 6 volt batteries, you can wire them in a series to obtain 12 volts.
Under normal use conditions- lights, propane refrigerator, charging phones etc and water pump, a 12v battery will last 2-3 days.
If you have a large enough space in your RV to add more batteries, you can add a third 12 volt – 100 Ah battery connected in parallel. However, it is not recommended to make more than three parallel connections.
