hydrogen gas from sealed batteries?

phildcamp · 15th October 2008, 02:56 AM

hi guys. I'm gonna be using a cascade DC power supply to run my car amps in my home. I really want to use a good battery with it to handle the transient surges. I figured I could use a sealed battery, till someone told me they still release hydrogen gas, just alot less than a regular battery. now I don't know. how bout you guys?

Ideas, suggestions. please and thank you.

or how about dry cells. maybe this one.

peace

Gel cells are used indoors for emergency lighting, UPS systems and such with no problems. I wouldn't use a car battery, sealed or otherwise indoors. Not only is there the hydrogen problem, but I'd worry about corrosive vapors, especially if overcharged. IMO, batteries aren't as good as a conventional power supply with lots of storage capacitance in terms of noise and stability.

I have a car jump start box someone gave me with broken clamps. I took the battery out and it sure looks like a sealed gel battery, though I was thinking of mounting it near my car amp in the trunk. Can buy jumpers here for $30 last time I looked, this one is just a cheap one. Is smaller than a car battery of course.

so I learned all lead acid batteries (wet cell, gel cell, absorbed glass mat) can "gas" but you never really know if they will/are for sure.

they shouldn't during normal charging, and can during over charging. clear as mud right!

thanks for your ideas guys. I may look into this a bit more, but I think I'll pry go with out the battery. I'm sure they would be fine. but I don't want to find out the hard way.

peace
