not over kill, but extra run time.

your ups should be in neighborhood of a back-ups rs [shown as br1500];

load   time
watts  mins.
 865     3
 400    15
 300    23
 200    40
 100    60

load wattage is design of system and can not be increased.

run time is determined by battery amp/hour. most apc ups have 2 12 v
gell cell batteries in series. if you want to increase your run time,
you can use more cells external of case. just use 2 'y' spade connectors,
run wires [12 awg or 10 awg] to external batteries.

my only complaint about apc is that they use mov [metal oxide varistors]
for surge and spike.

one day i hope they will change and use sasd [silicon avalanche suppressor
diodes] made by 'transtector', http://www.transtector.com. check their site
and you will see why i have installed them on all my clients systems.
