Tripp Lite AVR900U AVR 900VA Compact Line-Interactive UPS 12 Outlets 900 VA

For the first few weeks it had a chemical smell that would make you sick. Eventually that went away. It operated fine during the few power outages I had. With only my router plugged in, it lasted for 2 hours during an outage. It is now 2.5 years after I bought this unit (700va version) and the battery no longer holds a charge. Given it was only discharged fewer than 10 times, I would have expected another year at least, out of the battery. It has always concerned me that it runs very warm to the touch whether on line power or battery. I wouldn't call it hot, but very warm. I've never had a ups that was always warm, so it makes me uncomfortable, like it's one step away from overheating. Due to the heat issue, I think I'll replace the unit with another brand instead of investing in a new battery.

Durn good product with amazing insurance for down stream equipment. I will not buy the others.

perfect for what i need

I bought the AVR900U to replace a cheap no-name UPS that failed after less than a year. It is providing battery backup for the following network equipment: Peplink Balance 20 Router SB6141 Cable Modem Arcadyan KVD21 Gateway Trendnet TE100-S16Eg Ethernet Switch Aumox SG308P PoE Switch Obi100 VOIP Gateway Obi202 VOIP Gateway There are also several small cooling fans connected to the UPS. After installing the new UPS, I let it run overnight to charge the battery. Then I disconnected it from the power to test how long it would provide backup. It ran for 75 minutes before finally quitting. This is on a new battery, so I'll have to wait to see how long it runs after the battery gets older. I like the fact that Eaton/Tripplite provides a 3-year warranty, so if it fails before then, I can get a replacement. When the time comes, it appears that the AVR900U is designed so you can easily replace the RBC51 battery. Unlike many other UPS, it did not continuously beep while running on battery (which is very annoying). It only started beeping about two or three minutes before the battery died. Also, when I restored the power, the UPS restarted automatically and provided power to all the equipment. This is unlike a few other UPS I have used, which often fail to restart after the battery is run down and require you to push a button to get things going again. This can be especially troublesome if the equipment is at a remote location (as I have learned the hard way). A good UPS should always restart after power is restored, regardless of the battery condition.

Unit would constantly shut down while working. After speaking with their support they tell the battery was at fault and shipped a new one. Not long after it began again. Unit is now disconnected and I will not re install or recommend this product.
