This must be the issues with AGM batteries because I just replace my motorcycle battery AGAIN after a couple years. NEVER had issues with regular batteries in vehicles until I started using AGM batteries. There goes 300 bucks. 150 for the motorcycle battery less than a month ago as well.

Anyone have issues with batteries? I had the original battery in my Harley for over 10 years and never hooked it up to a battery tender like the first 5 years. Would always start after winter just sitting.

I don't drive the Z until it's nice out, usually March until November, then it sits for a couple weeks in the garage, most of the time on a tender. Always on a tender during winter.
