When you get an alarm or ups battery from Century Batteries you can trust it when the power goes down to keep you safe and help save all your work. Century Batteries in Abbotsford or Port Coquitlam stocks a full line of all the common back up power batteries so you can walk in and get what you need today so that alarm panel beeping (that always seems to go off at 2 am) doesn't keep you awake longer than necessary.
