How to Choose the Right CR2430 Equivalent

When choosing an alternative to the CR2430 battery, consider the following:

Voltage and size: Verify that the battery size (24mm x 3mm) and voltage (3V) meet the device requirements. Refer to the manual or the battery compartment label.

Battery type: Most alternatives (e.g. DL2430, ECR2430) are lithium batteries, but different brands and types of batteries vary in performance. Select the right type of battery according to the specific requirements of the device.
