I have a 2000 R6 I bought a few years ago
Anyways replaced the battery last spring with a western powersports battery and put it on a battery tender jr all winter and it was dead come spring
Charged it using a big charger at work on slow charge so it took few hours and was reading full charge when I took it off and of course it rained for 3 weeks straight went to fire it up this morning dead battery again
I don't have any dead shorts I'm sure as it sat for a month last year and fired up no problem on old battery
So basically are these western powersport batteries garbage or do batteries typically only last a season???
