When using a uninterruptible power supply how long does it preserve the original capacity? Say I buy a UPS that holds the necessary load for 10 minutes – I don't want it to unexpectedly come into state when it dies 30 seconds after a blackout starts.
Hw many years does it usually take to exhaust the battery without its misuse and abuse? Are there any known examples?

My main APC UPS is on year 3 with it's current batteries and it's still doing fine. However, I will be bringing in a technician to run some tests to ensure that this is the case. The city I am in recently had a major power outage in it's downtown core. My UPS kept our systems up and running for 25 minutes until it was restored. I was quite impressed.
Keep up regular maintenance and have a technician look over your solution. It's a small price to pay to avoid being left in the dark.
