OEM Grom Battery
Yuasa YTZ5S-BS High Performance AGM Battery
This is the new generation of maintenance-free batteries from the largest motorcycle battery manufacturer in the world! Over 50 years of engineering expertise ensures high-quality construction for long and trouble-free service. Their use of Absorbed Glass Mat (AGM) Separators is an advanced battery technology that eliminates the need to ever add water. Their advanced lead-calcium alloy holds its specific gravity more than 3 times longer than conventional lead antimony batteries. This equates to a battery that can go much longer between charges when used in standby mode, like winter storage. This is truly the world's finest "install it and forget it" motorcycle battery! Ron Popeil would be proud.
