Upgraded to a 350. First one hummed to drive the office crew wild. APC replaced it. Second one hummed louder with a stutter every 4 seconds so you would be sure to notice it.
old software documentation doesn't match the software, which is odd since the software itself hasn't been updated in 5 years so how old does that make the documentation? I replaced the battery in my UPS but the software (v3.0.2) reflects I have less than 1 minute of battery. The documentation says to reset the battery replacement date, but where? It does not say, and looking at the most recent (again, 5 years old) software interface provides no indication where I can do that. Nor is there any place to trigger a battery self-test, which is also mentioned in the documentation. So, if I can't get the unit to recognize a new battery I may just change to a different vendor. In the apc forums someone said they used a really really old version of powerchute (v1.x) and in that version they were able to reset the replacement date. This shouldn't be necessary. Plus, this site no longer provides those other versions for download so how am I supposed to try that method if I don't already have an old version archived on my computer from a previous download?

Needed to replace my APC ES350. So I decided to go with this model since I have the larger 1500 versions that have been running for years without a problem. It has been a few months now using this for my modem/router and it has performed amazing. What I replaced was actually the second ES350, which honestly are junk, they typically die within a year and replacing the battery only extends this another 3-6 months before the rest dies, usually killing a good battery inside. I went through 2 ES350 models within 30 months which is abysmal when my XS1500 models have been running for years flawlessly (only need to replace the batteries every 3-4 years).
When your UPS desktop needs aren't very demanding these little beauties work great! Just as dependable as the larger models. Definitely check these out!
