Re: TekSavvy Down It could happen, here is an example of a battery issue in a APC smartUPS UPS (I think it’s the 2200 model, the pic looks identical to one I have...minus the damage  ). The right most battery has broken internally (short, overcharged, or just plain broke) and had been generating gas for some time. SLA batteries do have a vent valve that is designed to release the excess gas; however nothing is 100% reliable. It failed as well and the preasure built up over time causing the cell to swell up. Assuming the rest of the UPS is unaffected you have to disconnect everything and remove the top cover do remove swollen batteries (a rackmount UPS with batteries in it is a very heavy thing to move).

kudos:6 | Interesting.
I have encountered some smaller APC's where the battery had swelled to the point that it had to be Pried out. |

I had always supsected they're running the float voltage too high. A few years ago, I was at a lunch seminar and was seated at a table with one of the founders of APC, and he basically confirmed (without actually saying it...) that some units have a problem with float voltage regulation, that might cause battery failure. |
