Capacity and voltage limits

The cell delivers 2300mAh at 7.4V for 17.02Wh of energy, using lithium-ion chemistry. A new pack reaches its best runtime after two or three full charge and discharge cycles. Using a low-quality third-party charger can reduce overall service life.

Physical fit and connector check

Dimensions are 118.70 x 55.00 x 40.10mm and weight is 146.0g; verify that your radio’s battery compartment matches these measurements. Confirm the connector on your original battery matches the replacement before ordering. Ensure the device model number and original part number correspond to the listed compatibilities.
