Battery and charger kit for Motorola Talkabout

The Kastar M53615 kit includes a 1650 mAh Ni-MH battery and an LTD2 dual USB charger. It replaces compatible Motorola battery models such as 53615, HKNN4002, and PMNN4477. The charger powers two batteries simultaneously from a 5 V USB source.

Upgrade from single-slot or proprietary chargers

The LTD2 accepts both Micro-USB and Type-C input, so you can use common phone cables or power banks instead of a dedicated wall adapter. The jump is worth it when you need to charge two packs at once during extended field use or group outings.

Verify your radio model before ordering

Check that your Talkabout unit appears in the supported list covering MR350R, T460, T600 H20, T82 EXTREME, and dozens of other model numbers. The battery voltage is 3.6 V and dimensions are 50.29 x 42.4 x 14.37 mm; confirm the compartment fits these measurements.

Questions about this item

What are the exact dimensions of the M53615 battery so I can confirm it fits my Motorola Talkabout radio?

The M53615 Ni-MH battery measures 50.29 x 42.4 x 14.37 mm (1.98" x 1.67" x .57").

How do I correctly connect the LTD2 charger to power, and what is the common mistake to avoid?

Connect the supplied Micro-USB cable to either the Micro-USB or Type-C input on the charger using a 5 V 2–3 A power adapter; the common mistake is using a lower-current USB port which prevents charging.

When should I replace the 1650 mAh Ni-MH battery in my two-way radio?

Replace the battery when talk time drops noticeably or the charger LCD indicates the cell no longer reaches full capacity after a full charge cycle.
