I am wondering about running a UPS on a super-cap array (I'm tired of replacing the battery)

should be able to hold up 100W for about 3 mins (some of this will be powering the UPS itself)
I was wondering what algorithm a UPS uses in general to test its batteries, and if a super-cap array like this will trigger the battery alarm or not. Hopefully the charger will also be happy.
At first I was worried about the need to balance the array (with zener diodes), but since they sell it as an array, I suppose this is not a real concern.
These 2600F capacitors can now be got used for about $10 each
