Dry battery

To make a long story short, I'll just ask my question- Does keeping the battery on a charger for several days "boil" the battery dry??~~Pat

If it is a "standard battery charger" without a smart monitor, YES.

It is best if you get a Battery Tender, 750 mA is plenty good. ( 250 mA is just good enough to keep a good battery charged all winter, it will not charge a dead battery )

750 mA is enough to bring an "almost dead" battery of say around 10.5 volts back to normal in a day probably.

If the battery is just down a bit, say 11.8 volts, it will be ready to ride in and hour or two.

Now, if the battery is dry, that means you have a Wet Cell,
so please, do yourself a favor and get an AGM battery.

they are much healthier, and won't go dry.
Plus they hold up their terminal voltage much better under cranking conditions.

A "dumb" battery charger it's a risk yes, a smart battery maintainer such a Battery Tender no. Even AGM batteries can vent and be damaged by prolonged use of a dumb charger.
Winging it every chance I get 8-)
