Verify Radio Model and Part Number

Confirm your handset is a Kenwood NX-200, NX-300, TK-3320, TK-5220 or TK-5320 before ordering. Cross-reference the original battery label against KNB-47L, KNB-48L or KNB-50NC to ensure the connector and form factor match. Inspect the battery compartment for damage or corrosion that could prevent a secure fit. Charge each pack fully before first use.

Thermal Behaviour and Power Draw

Normal operation keeps cell temperature within safe limits thanks to the built-in protection circuit. The pack delivers its rated 2600 mAh capacity at 7.4 V without excessive self-heating during transmit cycles. No audible noise is produced by the chemistry or electronics.
