Battery backup & hydrogen gas?

[epicfish]

I read the warning in the manual for the battery backup.

Why might it leak hydrogen gas. And is it dangerous in an enclosed space?

What's the composition of the batteries? Any warranties in case of damages resulting from any accidents due to leaking hydrogen gas from the battery backup?

Thanks.

Check out the technology of batteries. Hydrogen gas is a normal part of the charge/discharge cycle, do you have a warranty on the hydrogen gas that comes from you car battery? Or for that matter the hydrogen sulfide gas from the deep sand bed?

No, but they don't sit in confined spaces either. I planned to put this in a box underneath my stand to protect it from any splashing water, salt spray/creep, or water vapor from the sump. That would cause the build-up to be quite concentrated.

Release from car batteries is vented. And I don't have a deep sand bed. If I did, it wouldn't be in an enclosed box like I plan to do with the battery back-up.

I think it's a valid concern, especially when spending $420 for a pump and $150 for the battery backup.

Any helpful replies would be appreciated.

Thanks.

I have forwarded this request for information to IceCap who should chime in as soon as they can.

I don't really understand why you're being so defensive about this.

HS gas from a DSB has been proven to be dangerous over time and it isn't even the same thing. As to the car battery analogy, think about how many cells that battery has and how long the lifespan is.

Now consider the size of the battery back up. A release of hydrogen would in all likelihood indicate an irreversible reaction, reducing the lifespan of the battery over time. I could not find info on its composition (Li ion, Nickel Cadmium, etc.) and there is no expected lifespan posted.

Granted that not every company posts a lifespan, this point I understand. However, I am buying this in case of an emergency so I would like to know what the rates of H2 gas production are, and how often I should expect to replace the battery etc.

There wasn't any malice implied in epicfish's post, and these are extremely valid questions. Thanks Tim for forwarding this info to Icecap, I too would appreciate this info

Any updates?

Thanks.

The amount of gas that possibly could leak is extremely minute. The only possibility of any adverse action is if you contain the battery unit in a sealed space. Just place it where there is adequate ventillation and there will never be a problem.
