Alarm System Batteries

Mr Positive’s most common alarm system batteries. We have found that most home alarm systems use one of 4 alarm system battery sizes, as listed below. There are subtle differences between each alarm system model. This makes it very difficult to list every alarm system’s compatible battery.

A combination of the four models below would provide compatibility with 99% of standard home alarm systems installed in NZ. The most common of the four by far is the 12v 7ahr (also known as 7.2ahr or 7.5ahr).
