Description
The Trojan J185H-AC is a 12-volt, 225 Ah flooded lead-acid battery for trolling-motor runtime and house loads such as electronics, lighting and pumps. It weighs about 126 lb, so plan for a secure, vented battery box and a solid hold-down. The case follows a BCI 921 footprint; confirm your tray size and terminal orientation before you buy. Reserve capacity is 440 minutes at a 25 A draw. As a flooded battery it needs periodic electrolyte checks and top-ups with distilled water.
