Level of battery charge

[GoldOxide_imp]

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.

Ditto. I trickle charge about once per month during the slow winter riding season. Maybe once or twice during the normal riding season.

Smart trickle chargers are suppose to handle the job of healthy batteries too. However, I feel low grade (cheap) "smart" chargers may "over bake" batteries. So beware.
