Three years two batteries. Now I guess I'm ready for #3. The one that came stock lasted about 1 year or so. When looking for a replacement I was told the MOTOBATT MBTX9U battery was "the best motorcycle battery money can buy".So I bought one. On 5-5-18. The battery rating is 160 CCA (cold cranking amps), and 10.5AH (amp hours). So 20 months later now it's 2-20-20 and it looks like I'm up for another one. What is the best brand? I've heard about the Yuasa brand before. Also, some say a trickle charger will destroy some batteries. Is that true? How much trickle and when to use, if any. I know some batteries like to be discharged fully and recharged again, to help keep their charge. What's up with my battery blues? I've got a battery isolator cut-off switch with only the ignition wire (for odometer, and clock power) directly on the battery. Maybe I just got a bad Motobatt and should just buy another one. Or maybe they're only designed to last one year, planned obsolescence and all. Any suggestions? Does anyone ever modify to fit a slightly larger sized battery? Binford anyone? Just askin'
