Battery Replacement

Hi,

Our UPS, installed by Bell Aliant, has low battery and won't stop beeping. We called and they informed us it's an old model they no longer service (Model C, from here). They suggested they would need to replace our modem and everything else to switch it out, which I don't want to do as the modem is running properly and the last thing I want to do is wind up with a refurbished modem that has issues just because of an annoying beeping noise.

The battery specs appear to be, from that post:

  • 12V VRLA (Valve Regulated Lead-Acid) battery
  • 7.2 Ah
  • Length: 151 mm (5.94”)
  • Width: 65 mm (2.56”)
  • Height: 93 mm (3.66”)

Am I able to just buy a battery myself and replace it? If so, could anyone point me to one that'd be compatible?
