Description
The Trojan J305E-AC is a 6-volt, 305 Ah flooded lead-acid battery for house loads such as electronics, lighting and pumps. It weighs about 83 lb, so plan for a secure, vented battery box and a solid hold-down. The case follows a BCI 902 footprint; confirm your tray size and terminal orientation before you buy. Reserve capacity is 645 minutes at a 25 A draw. As a flooded battery it needs periodic electrolyte checks and top-ups with distilled water.
