Compatible Kenwood Radios

The KNB-33L lithium-ion battery pack fits a wide range of Kenwood portable two-way radios including the TK-2180, TK-3180, TK-5210 and TK-5310 series. It replaces the original KNB33 7.4V 1800mAh cell and meets or exceeds OEM specifications. Users of these specific models can install it directly without modification.

Drop-Tested Durability

The pack survives six drops onto all six sides from a height of six feet without breaking or losing power. This rugged construction suits field crews, marine operators and security teams who work in rough conditions. Buyers who need a lighter cell for occasional indoor use or who require a different voltage platform should look elsewhere.

Build Integration

The battery slots into the radio’s existing compartment and uses the standard charging contacts, so no extra adapters or wiring are needed. Its 1800mAh capacity frees the operator from frequent swaps during a full shift. An 18-month warranty covers the pack against defects in materials and workmanship.
