I just picked up a crown 35rr picker with 1500 hours, ironclade work hog 24v batteries and hobart charger. Previous owner didnt use much nor did he know much about it, could barely drive it out of his shop. Anyway,

I didnt have 220 in my shop so i connected charger to generator and plugged her in for awhile. Seemed as though she charged from a red light (very low) to a 1/4 full after a couple hours. Used it a bit to check it out and in no time she dropped back to the empty state (red light) so i plugged her in a again. It never came back to the 1/4 full state after, can drive it but no lift.

I now understand that charging batteries are a bit of a science and and I figured it may be wise to get some good advice/direction before i start plugging and unplugging like a jackwagon. (for now, can I use the generator for charging? or should I wait to get 220 I installed in the shop?)

Charger has the daily and weekend selector...

Sorry I really dont know much about these systems (yet) but respect them and really would like to salvage as much remaining battery life as possible, if possible.

Recommendations?

Thanks folks, appreciate your time and wisdom.
