I bought 2 new Maxx 29's for my trolling motor. I have a promite 5/5/3 on board charger. I installed yesterday afternoon. I was surprised/worried this morning when both green and red lights (indicating still charging). My old batteries would recover overnight after total depletion.

I did somehow make a "spark" while finishing up the connections. Could I have damaged the battery/batteries?

SHould new batteries take longer on initial charge?
