Good luck with it, and let us know how it does for you.

Seru,

Do you keep the bike on a Battery Tender/cTek/etc. when you're not riding? My first battery lasted forever (like, five years!).
I've a MotoBatt in it now. And I keep it on a cTek US800 when I'm not burning dinosaurs. Well, not directly.

While that won't hurt anything, it probably is totally unnecessary......unless you go a LONG time between rides.

Even a cheap conventional battery doesn't need a tender for the first couple of years of it's life.......and an AGM almost never needs one......if the bike is ridden regularly.

All that assumes a properly working charging system. If the charging system is NOT working correctly, keeping it on a tender will almost guarantee that you run out of juice FAR away from home.

Agreed. Unless you're mothballing the bike for Winter, or only riding once a month, the trickle charger is unnecessary IMO. Even the Shovelhead's batteries would last 3 years with regular riding; the Suzuki's went almost 4. My car's OEM battery only lasted 2.5!

Be cautious about the lithium batteries that require a specific tender to balance the cells - these batteries aren't balanced when run in your bike and can have some issues. There are better batteries out there that have onboard battery management systems built into them and will work with any charger. Those are a mcuh better choice for longer life.
