[PSUBS-MAILIST] battery charge level

["Brian Cox" <ojaivalleybeefarm@dslextreme.com>]

Ok, this is a stupid question but it has been bugging me.
         How do you know how much charge you have in your batteries?   Other
than keeping track of how long you have run your motors how can you tell.
I know that the wwII subs would have to check the battery acid levels to
accurately know how much power was in the batteries.  But with the sealed
AGM or gel batteries you can't measure the acid, and chances are you
wouldn't be able to anyway in a small sub.

Thanks,

Brian Cox
