We spent 23 hours on research, videography, and editing, to review the top picks for this wiki. If you are running multiple servers, computers and network equipment, the last thing you want is a power failure to come along and knock out service, losing you valuable working time and, potentially, precious data. A reliable rack mount UPS can prevent that from happening by kicking in backup batteries automatically and keeping your system powered up long enough to shut down safely. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best rack mount battery backup on Amazon.

Editor's Notes

March 20, 2019:

Rack-mountable battery backups take the power of a traditional uninterruptible power supply and put it in a convenient form factor. They're mostly intended for commercial use in media closets and network setups, and if you're in the market for one, you've probably got at least a little professional IT experience. So, we consulted with a couple online resources to see which brands and models are preferred by industry pros. Notably, Eaton apparently makes highly reliable units, and although their brand doesn't reach quite as far in the consumer market, they receive considerable praise from those in the know. For a very well-known option, it's hard to go wrong with anything by APC, and here we've highlighted their newest and most reliable line-interactive as well as on-line versions. CyberPower is another company that's a bit obscure, but makes a handful of high-quality and reasonably priced models. Similarly, Tripp Lite makes some affordable options, and the one listed gets good marks from technicians, and is relatively full-featured. Finally, Vertiv is a renowned power-distribution manufacturer, and particularly their Liebert PSI-5 is among the highest-performing models, though it is considerably expensive.
