Call me a moron...I thought it was a maintenence free! I went to check my electronics and after two months of storage my battery was so dead it wouldn't even light up the "charging" indicator on the battery charger. I discovered the plates in the battery were dry. I must have "boiled off" the electrolite by overcharging??

I added distilled water and it has taken a charge but my question is, "will it handle the load of an electric motor" in the future? Or, is it shot? It's a 27 series deep cycle that I use as an "accessories" battery.

Check it with a battery hydometer.

I would not depend on it. I have had a similar experience. Boiled away all of my water. As you did, I refilled it with distilled water. It worked with greatly reduced capacity for a short while. I replaced it within a week.

Duncan, yes give it another try with fresh water and make sure your using a regulated deep cycle battery charger not a starting charger --- Let it charge up then take the the individual cell hydometer readings --- water shouldn't have evaporated with the correct charger in 2 months ---

One bad cell and it's trash time I'm afraid.

What was the warranty --- go for replacement if still has one left --- Z

I've forgotten exactly why it's necessary but I have a battery load tester which essentially is a big resistor. Hook the clamps up to the terminals and hold the 'on' switch for 10 seconds while watching the indicator to stay in the OK area. Oh. You need to check with a hydrometer first to make sure it has a full charge. The only reason I can remember is that a good battery not only holds a charge but also has to provide a load. I'm sure someone on here can explain better and I hope they do.

You can have a service station check it under load or buy one for about $60 then have it for life.

The reason I have one now (load tester) is that sailboat batteries are relatively expensive and also it's a hassle (heavy) taking them out to have them checked every so often.

Where can I get a hydometer? Any link? It's different from hydrometer, isn't it?
