Replacement Ni-MH Pack for Kenwood Radios

The Estry TH-46AT is a 7.2 V 700 mAh nickel-metal-hydride battery built to match the original specifications for a wide range of Kenwood two-way radios. It fits models such as the TH-46AT, TH-78, TK-220, TK-25A, TK-330 and TK-340, and replaces OEM part numbers PB-13 through PB-18. The pack measures 57.52 x 48.15 x 30.0 mm and weighs 181.0 g.

Upgrading from Worn or Lost Original Packs

Users whose factory packs no longer hold a charge or who need a spare for extended shifts can swap in this unit without modification. The jump is worth it when the original Ni-MH cells have degraded below usable run-time or when a second pack is required for continuous operation. It is not suited for radios that require a different voltage, connector layout or higher capacity than 700 mAh.

Capacity and Practical Headroom

At 700 mAh and 5.04 Wh the pack delivers several hours of typical transmit-receive duty on a single charge, supporting routine professional or recreational use. Runtime shortens under continuous high-power transmission or in cold conditions where Ni-MH chemistry loses efficiency. The integrated protection circuit guards against over-charge, over-discharge, over-voltage and short circuits to extend service life.

Questions about this item

What are the exact dimensions and weight of the Estry TH-46AT battery so I can confirm it fits my radio's battery compartment?

The pack measures 57.52 x 48.15 x 30.0 mm and weighs 181.0 g.

How do I install the battery and which orientation mistake should I avoid?

Slide the pack onto the radio chassis until the locking latch clicks; the contacts face the radio body, so inserting it backwards prevents connection.

When should I replace the 7.2 V 700 mAh Ni-MH pack and what is the correct part number to reorder?

Replace when runtime drops sharply or the pack will not hold a charge; reorder using part numbers PB-13, PB-13H, PB-14, PB-15, PB-17 or PB-18.
