Level of battery charge

[the Ferret]

I never do this. Instead I try to ride my bikes on a regular basis year in, year out. A bike takes care of its battery while being ridden like no charger in the world can do. Some numbers of the first batteries of my bikes, which still work: CB - nearly 7 years, W800 - nearly 9 and Bullet - nearly 4. Some more years to come I guess. Maybe it's all part of a seldom battery luck.

Wisedrum

I ride my bikes almost daily year in and year out too Wisedrum, over 300 days and 25,000 miles most years. This year looks like a little less than 300 day year and about 20,000 miles due to health issues I've had, butIi haven't had to worry about my batteries. A battery tender jr only adds juice if the battery needs it, otherwise it just maintains it. There are no highs and lows in the state of the battery.
