Replacement 7.5 V 1800 mAh Li-Ion battery for Kenwood NX-200, NX-300, TK-5220 and TK-5320 radios

  • Survives six 6-foot drops on every side without damage
  • 5 V 1800 mAh lithium-ion chemistry powers compatible Kenwood radios
  • Fits NX-200, NX-300, TK-5220 and TK-5320 models directly
  • Built with highest-grade cells for reliable long-duration operation

Compatible replacement for Kenwood NX and TK radios

This 7.5V 1800mAh lithium-ion pack replaces the original KNB-47L cell used in Kenwood NX-200, NX-300, TK-5220 and TK-5320 portables. It fits the same battery compartment and connects to the existing charging contacts without modification. The unit is supplied new and ready for immediate use.

Sustained output and drop-tested durability

The pack uses high-grade lithium-ion cells selected to maintain voltage over a full duty cycle rather than sagging after a short transmit burst. Manufacturer testing confirms the case survives six drops from six feet onto all six sides without cracking or losing power continuity. An 18-month warranty covers defects in materials and workmanship.

Check radio model and voltage before ordering

Verify that your handheld shows one of the listed model numbers and that the original battery is rated at 7.5V 1800mAh. The pack will not fit radios that require a different voltage, capacity or physical latch design. No charger or radio is included in the package.
