Very much respect your experience. I disconnected both leads back in the late summer, and the battery sat there in the bike, in the dark, in a cool (now cold) garage. But it lost a good bit of its spunk. I probably will replace it eventually with a good-quality gel battery, especially if it starts having problems. I would like to give it one good charge (not the 30-minute special I got), and see how that holds up. Just don't know how to go about doing this -- both the device to do it and the method.

I do like those Battery Tenders but I've not found any outlets here in China.

thanks!
