I bought a Honda 450ES in 1999 (ES stands for Electric Shift). It has run flawlessly. I have over 3000 miles on it and around 1400 hours. For the first 5 years I had it the battery worked every time I was ready to use the ATV. Once the 1st battery died I've had constant problems keeping any battery good for more than one year. It's driving me bonkers. I needed the ATV today and of course it was dead. I pull started it, no problem (synthetic oil made that task very easy
). Got 10 feet from the pole barn and it died. I had ran it for a few minutes, but still when it died in gear the battery didn't even have enough juice to let me switch gears back to neutral. First time that has ever happened. But what a pain. It started sleeting rain and I had to get the tools to get at the battery and put my charger/starter on it so I could simply change to neutral. I got soaked and so did the ATV.
I have a battery tender. so I'm figuring I need to make up a quick attach hook up for it so I can charge the ATV battery easier.
Any other ideas on GREAT batteries or something else to try?
