Ni-MH power for Motorola TalkAbout radios

This two-pack of 3.6 V 1650 mAh Ni-MH batteries and the LTD2 USB charger replaces Motorola part numbers such as 53615, 1532 and HKNN4002A. It fits TalkAbout models ranging from the T200 series up to the T82 Extreme and T92 H2O. The bundle suits hikers, event staff or families who need spare cells for multi-day trips without access to mains power.

Drop-in cells and dual-slot USB charging

Each battery matches the original 50.29 x 42.4 x 14.37 mm form factor, so they slide into the radio’s battery compartment without modification. The LTD2 charger accepts Micro-USB or USB-C input at 5 V 2–3 A and charges one cell at 8.4 V 800 mA or two cells simultaneously at 4.2 V 800 mA each. An LCD shows individual capacity and charging status. A Micro-USB cable is included; a USB-C cable is not.

Ni-MH chemistry and USB current limits

Ni-MH cells self-discharge faster than lithium-ion, so they should be topped up before each outing. The charger’s 800 mA per slot means a full charge takes several hours from a standard 5 V source. Output voltage is fixed at 8.4 V for single-cell and 4.2 V for dual-cell mode; the unit does not support quick-charge protocols or higher-current USB-PD profiles. Radios requiring proprietary desktop cradles will not charge through this adapter.

Questions about this item

How can I confirm the LTD2 charger is charging both 1650 mAh Ni-MH batteries correctly after plugging it in?

The intelligent LED display shows real-time charging status and battery capacity for each slot; when both indicators read full the batteries are ready for use.

The box contains two 3.6 V 1650 mAh Ni-MH batteries and one LTD2 dual-slot USB charger with a Micro-USB cable; any 5 V 2–3 A USB power source (wall adapter, power bank, car charger) will run it.

Which Motorola TalkAbout models are covered by the 53615 / 1532 / 56315 battery cross-reference?

The batteries replace Motorola 53615, 1532 and 56315 packs and fit TalkAbout radios including T5710, T5720, T5800, T5820, T5900, T5920, T5950 plus the EM, FV, MC, MD, MJ, MR, MS, MT, MU, T and H2O series listed in the compatibility table.
