My APC backup ups 1100 lasts only for 10 minutes.

Devices plugged in are an iphone to charge a mac book to charge

and after it beeps and shutsdown. I can not turn it on again. Only fan spins when I try to push the button. @Craig

If that is all you have plugged into it you have roughly 80 - 100 watts pulling on it. Which should be giving you about 75 minutes of run time per APC specs.

How old is the unit and have you had any power issues (building power) while using the unit? It sounds like you have a battery going bad and it can not hold the load as it should. Batteries typically last 3 to 5 years. Of course I have seen batteries last longer and shorter times as well due to a multitude of factors like clean(er) power temperature (environmental and battery), and the like.
