UA5 runs about 500mah so what ever mah's your battery is divided by 500.

How long will my battery last?

Depends on the battery's capacity (usually measured in mAH, or AH).  The UA5 draws about 450mA.  Divide your battery capacity (mAH) by the current draw (450mA) to get an approximate run-time.  For example, a 3000mAH 9.6v RC battery will yield ~6.6 hours of run-time (3000/450) .  Better to be a bit conservative in your calculations for practical usage, though - the battery may not be fully charged and you likely won't eek out every last bit of juice from the battery.  A good 5 hours is probably a reasonable estimate in this case.
