Two-pack KNB33L 7.4V 1800mAh batteries

This two-pack supplies two replacement Li-ion batteries rated at 7.4V and 1800mAh for Kenwood two-way radios. They are built to meet or exceed the original KNB33L specifications and carry an 18 month warranty. The cells are selected for consistent performance in demanding environments.

Teams needing drop-tested spares for compatible

The pack suits organisations that want ready spares for radios such as the TK-2180, TK-3180, TK-5210 or TK-5310 series. Each unit is tested to survive six drops from six feet on every side without loss of power. Buyers who need a different voltage, a higher capacity or a battery for a non-Kenwood radio should look elsewhere.

Verify your radio model matches the listed part

Before ordering, confirm that your handheld uses the KNB33L or KNB33 battery and that the model number appears in the compatibility list provided. The batteries are 7.4V Li-ion packs; using them in a radio designed for a different chemistry or voltage can cause damage. No charger is included, so ensure you have a suitable charging solution already.
