Choosing the right battery for your Mobeye device is more straightforward than it might seem — but it does matter. The wrong brand can drain faster, perform inconsistently, and even prevent your system from sending critical alerts when it counts most. This page explains which CR123a battery brands work reliably with Mobeye products, which to avoid, and how to fit them correctly.
Mobeye products use 3.0V lithium CR123 batteries, also known as CR123a. The CR123(a) is a cylindrical battery with a (+) nub at one end and a (−) flat end at the other. It is widely available in specialist shops and online. However, not all brands perform equally. Some CR123 batteries are poorly suited to Mobeye alarm and monitoring systems because of inconsistent peak current delivery — particularly after partial use. This typically results in a shorter battery life and, in some cases, the device failing to send a ‘low battery’ alert. Both issues directly affect the reliability of your Mobeye system.
