Battery charging

[Ray]

I do what Grumpy Goat does, a pigtail hooked up to the battery. I use a Deltran Battery Tender and I leave it hooked up to the bike all the time. I have been doing this for about 15 years now. My last RS battery lasted 5 years, doing what I said, the Battery Tender hooked up whenever the bike is in the garage.

It's important to note that a battery tender is NOT a trickle charger, the battery tender will take the amps to zero and keep voltage on the battery. A trickle charger NEVER lowers the amps to zero and will damage a battery if left hooked up all the time. The Optimate and the Deltran are battery tenders.

Right. What they say.

For what it's worth, I got suckered by marketing into buying the Optimate 4 CAN bus version.... It now does duty on my emergency generator battery while the motorcycle remains happy (5 y and counting) on a C-tek smart charger hooked to the same plug attached directly to the battery that was used by the dealership to keep their floor models charged. In the end, I saw no reason to keep my CAN bus in the loop.
