Who should choose this battery

Technicians maintaining compatible RKI gas detectors will find a direct-fit replacement with overcharge, over-discharge, over-voltage and short-circuit protection. Buyers needing a different voltage, chemistry or capacity should look at other options. The cell is not suited for devices that require a proprietary connector or a higher energy density than 1.2 Wh.

Critical specification for fit

Voltage and capacity — 1.2 V and 1000 mAh — determine whether this pack powers the target instrument correctly. Confirm the device manual lists these exact values before ordering.
