Yikes. I am probably spinning my wheels here.your battery
needs fluid covering the cells if it is lead acid like a car battery
. You lift
the covers and fill with ionized water
tell they have the right level. Your friend is messing around which is kind of funny
but if your battery is hot and your cooling
it with mists of water while underway he might be trying to kill you.
Batteries need good charge cycles good maintenance
. A hot battery may have a shorted cell. Might blow up. Might catch fire. Spraying water in a hot battery is like showering by pissing in the wind
. U will get wet but you will still smell like a porta john.
