Battery Fluid Down -again

[Chuck Ciaffone <chuckc@ibm.net>]

Howcum -- every so often, maybe in 6 months or so,
I'll check the battery fluid and it will be almost
dry. I put in several cups of water across the
6 holes. What causes fluid loss? Overcharging?

It's a 72 with an alternator with a built-in 
regulator. Not to old either - a replacement
unit - rebuilt.

And, I could almost swear, I check it every couple
weeks and it held steady for several months at least,
then today it's real low. Huh?
