Hot batteries with water misted

cold batteries or hot batteries which ones have more life like as in time?

How about misting the tops of the batteries, will that help them last?
Marina buddy says always mist tops of batteries with a spray bottle of pure water. This keep them cooler running longer he tells me. Lots of stuff he likes me to do. I dont know.
So I ask you if he know real truth or laughing?
he think batteries need frequent washing off.

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.

Lead acid battery. The outside of the battery must be dry and clean, must be clean and dry. If it ain't, something wrong.

Re: Hot batteries with water misted

I'm assuming the question is relating to for example. being in the south in aug when it's 110f. and the batterys are 110f. and if he managed to drop them down to say 80-90 would he get a couple more AH out of them.

probably a logical question. though having stuff on the top can cause cell to cell current leakage. so I would probably try something else. ice packs around the outside?

I don't think he's trying to ask if his batteries are boiling over with his 500a charger should he try to cool them down with outside means, instead of charging them properly.

Re: Hot batteries with water misted

Bubba, I think that your friend is either:

1. sadly misinformed

or

2. having a little joke with you

The amount of cooling afforded by "misting with a spray bottle" is trivial, and is not needed in the first place.

Find a better informed or kinder friend, and leave your batteries clean and dry.

Cheers,

Jim
