Napa Legend Import Battery, Group Size 49-6 it looks like to me. Good battery and very expensive.
Yes, your charger will work just fine. If that battery is dead, you need to slow charge it at 2 amps for 24 hours. If you have a larger smart charger I would use that 1st and see how the battery comes back and holds a charge. How long has it been sitting for.

It has removable caps. Good idea to remove them yearly to examine the electrolyte level. Use a #4 Phillips socket. Be careful not to strip the cap.

Replenish with distilled water.

I assume you have 24 hour power for the charger.

Is there a way to close the hood so the cord doesn't get in the way?

Will be plugged in 24/7 when there is salt on the road. I was hoping it was sealed without maintenance, oh well. Thanks for the tip.

I just let mine down on the safety latch. Lots of room.
