Questions about this item

What voltage and capacity does each 7.4 V 1600 mAh pack deliver in use?

Each cell supplies 7.4 volts and 1600 milliampere-hours, matching the original KNB-63 and KNB-65 specifications for Kenwood radios.

Will the 96.8 x 54.3 x 30.6 mm case fit the battery compartment on a TK-2000 or TK-3000?

Yes — the dimensions match the OEM KNB-63/65 form factor, so the pack slides into TK-2000, TK-3000 and all listed compatible models without modification.

How do I install the two-pack and what step causes charging problems?

Insert each battery until the latch clicks, then charge fully before first use; skipping the initial full charge is the step that reduces runtime.
