Cameron & Co DS-CS-KNB533TW 2.8 Ah Li-ion battery

This replacement pack fits Kenwood NX-5000, NX-5200, NX-5300, NX-5400, TK-5230, TK-5330, TK-5430 and VP-series radios. It replaces original KNB-L1, KNB-L2, KNB-L3 and KNB-N4 cells. Marine and public-safety operators get a direct OEM-compatible power source.

Thermals, noise and power draw

Lithium-ion chemistry delivers 7.4 V and 2800 mAh for 20.72 Wh capacity with no memory effect. The sealed cell runs silently and maintains stable voltage across the duty cycle. Low self-discharge keeps the pack ready after weeks in storage.

Build quality and daily use

The black housing measures 116.70 x 58.20 x 26.70 mm and locks onto the radio chassis with the factory latch. Contacts align with the original charging cradle so drop-in charging works unchanged. Not suited for radios that require a different voltage or form factor.

Questions about this item

How do I install the DS-CS-KNB533TW battery and what step is often missed?

Slide the 116.70 x 58.20 x 26.70 mm pack into the radio until the latch clicks; the step users miss is confirming the 7.4 V contacts align before forcing it.

What maintenance or replacement will the 2.8 Ah Li-ion cell need later?

Expect 300–500 full cycles before capacity drops below 80 %; store at 50 % charge if unused for weeks and replace when talk time falls sharply.

What limit appears first during sustained transmit on the 20.72 Wh pack?

Continuous high-power TX triggers thermal protection first; the radio will reduce power or shut down until the 26.70 mm thick cell cools.
