So far this battery is performing great. My 10 year old H-D AGM battery was giving me trouble, would not hold charge for more than a couple of days, then it would not start the bike. Since installing this battery a couple of weeks ago, I have not had to plug the trickler in and the bike turns over like a champ and starts every time. I bought the BRS smart trickle charger with this battery and will use it on the off season. We’ll see how it does long term next spring. I’m not too worried though, battery has a two year warranty.
