Questions about this item

How long will the 1600 mAh capacity actually run my Kenwood TK-3000?

The 1600 mAh lithium-ion pack delivers the same runtime as the original KNB-63L; exact hours depend on transmit power and duty cycle.

Does the 7.4 V output match the radio's charging and voltage limits?

Yes, 7.4 V is the nominal voltage specified for KNB-63, KNB-65L and all listed Kenwood models.

Will the 96.8 x 54.3 x 30.6 mm case fit the TK-2000 battery compartment?

Those dimensions match the OEM KNB-63 form factor, so the pack slides into TK-2000, TK-3000 and TH-K20 series radios.
