I'm curious about how long a typical "consumer" UPS can run on battery before it fails. What would the maximum run time be and what limits it. Never know when you'll need it for longer than a few minutes. If I were in the middle of editing media I would want as much time as I can get to get to a decent save point before shutting down. Same for games.
What Carlos wrote, but note I've bought a lot of these over a lot of years. Every one came in a box and/or with a manual with the information to answer jdebert's question. Just remember performance does not improve as the batteries age. Once batteries are 2 years old, maybe sooner, you should be routinely running the unit's self check to ensure you won't suffer disappointment when the power does go out. If you want a lot of run time, you either buy the biggest one that fits wherever it needs to fit, or make enough space for a bigger one. Also you don't use it to power things you can do without while the power is out. Put them on the surge-only outlets or a separate surge suppressor not plugged into the UPS. I've not read lately to see if it's changed since, but years ago the manuals said do not plug surge suppressor power strips into them, to avoid having them fail to respond properly due to their unprovided-for suppressive characterstics in circuit between UPS and protected devices. Hopefully that has changed, as finding power strips without suppression to fit the inevitable overabundance of external power bricks is no small task. The cheap strips without suppression almost always aim plugs to prevent more than about two bricks attached at once. I circumvent that nuisance buying 8" extension cords in 3-packs from WalMart for about the same money other places want for just one. -- "The wise are known for their understanding, and pleasant words are persuasive."
