I purchased this battery trackside for my streen bike during a track day in July 2013, after mine took a flop. I have only charged it over the winter when the bike was not in use. I have had no problems with the bike cranking or starting right up! I think it may be time for a replacement because I can't seem to get it to charge now but it was worth every penny spent and I will be purchasing another for my track bike as well.
Followed the instructions to a T in filling with electrolyte and then charging. Dropped it in and it fires up immediately going on a month now. A must have for turning over a big V twin. Ordered on a Monday, received on Wednesday, up and running on Thursday, left for a week long trip on Saturday with confidence it would start every time. Excellent fast delivery.
