Ajax CR123A 3V Lithium Replacement Battery
Summary
The Ajax Battery CR123A (part number 22256.87.NC) is the official Ajax-recommended Panasonic CR123A Industrial lithium replacement battery for use across the Ajax wireless alarm device range. Unlike standard CR123A batteries, this industrial-grade cell is derived from the Panasonic Photo series and is specifically engineered to maintain sufficient charge at temperatures as low as -10°C — making it well suited to outdoor and unheated installation environments.
With a high 1.4Ah capacity and low internal resistance, the battery delivers extended service life of up to 7 years in select Ajax sensors, minimising maintenance visits and ensuring ongoing system reliability. Ajax Systems strongly recommends replacing sensor batteries with this approved cell to maintain expected battery life estimates and system performance.
The battery uses lithium manganese dioxide chemistry, is non-rechargeable, and is compatible with a wide range of Ajax Jeweller and Baseline devices including motion detectors, door and glass break sensors, sirens, fire detectors, and more.

FAQs
Is this the correct battery for Ajax alarm sensors?
Yes. This is the Ajax-approved Panasonic CR123A Industrial lithium battery, which Ajax Systems recommends for use in all compatible Ajax wireless devices. Using the approved battery ensures the battery life estimates published by Ajax are accurate for your installation.
Can I use a standard CR123A battery instead of this industrial version?
While a standard CR123A may physically fit, Ajax recommends using this industrial-grade Panasonic cell. The industrial variant offers greater temperature tolerance, lower internal resistance, and higher reliability than standard CR123A batteries — all of which are important for security sensors that must operate continuously and reliably.
How long will the battery last in my Ajax device?
Battery life varies by device. For example, DoorProtect and GlassProtect sensors use a single CR123A and can achieve up to 7 years. MotionProtect and CombiProtect sensors achieve up to 5 years on a single cell, while devices such as StreetSiren and MotionCam Outdoor use four cells and achieve up to 3–5 years. Refer to the Ajax support pages for a full list of device battery life estimates.
Is this battery rechargeable?
No. The CR123A is a primary (non-rechargeable) lithium manganese dioxide battery. It should be disposed of in accordance with local regulations for lithium battery recycling once depleted.
What devices is this battery compatible with?
The CR123A is used across a wide range of Ajax Jeweller and Baseline devices including DoorProtect, GlassProtect, MotionProtect, MotionProtect Plus, CombiProtect, MotionProtect Curtain, MotionProtect Outdoor, DualCurtain Outdoor, MotionCam, MotionCam Outdoor, HomeSiren, StreetSiren, StreetSiren DoubleDeck, FireProtect 2 RB, Transmitter, Ajax WaterStop, and LifeQuality.
