We've got two '04 GX-SC. Robin's battery died last Oct. Mine died this season.

Robin's ski would start right up--but ran like crapola. That was in Oct. Took the battery out-- trickle charged it off and on over the winter. Took it to the shop this Spring-- ran like crap for them in the water too-- replaced the battery and its back to normal ! What gives there ??

I charged mine up on the trickle for a couple of days before taking it out last wekend-- guess what-- Started right up after 7 mo, but ran like crap. Put a new battery in and its back to normal.

Why would ours crank right up-- but not run with a weak battery ? Charger not enough to run them or ??
