I just installed a new X² Power battery into my cruiser today. It is manufactured by Northstar. It's an AGM, group 24 size, part# SLI24AGMDP. It is a perfect fit, putting out 1500 PCA, 840 CCA, and 160 minute reserve. The best part is the 5-year free replacement warranty. Its pricey, but worth it. I thoroughly cleaned the cable terminals before installing them onto the battery posts. My gauge is reading 13.1 volts with the key at ACC. It is also starting a whole lot better.
