Compatible Battery for Motorola Talkabout Radios

This lithium-ion pack replaces the Motorola 53615 and a long list of KEBT, HKNN, PMNN and NNTN part numbers used in Talkabout two-way radios. It delivers 3.6 V and 1650 mAh capacity for extended field use. The 5.94 Wh energy rating suits recreational and light commercial users who need a direct drop-in power source.

Dual-Port LTD2 Charger with LCD Status

The included LTD2 charger powers two batteries simultaneously through independent 800 mA channels and shows real-time capacity on an integrated LCD. Input accepts 5 V at 2–3 A via either Micro-USB or Type-C, and a Micro-USB cable is supplied. This flexibility lets operators top up packs from USB power banks, vehicle ports or wall adapters without a proprietary dock.

Simple Drop-In Installation

The battery matches the original 50.29 x 42.4 x 14.37 mm footprint, so it seats in the radio’s standard compartment without modification. The charger’s spring-loaded bays accept packs in either orientation and the LCD confirms contact immediately. The only common issue is attempting to charge a deeply discharged cell that has fallen below the charger’s detection threshold; a brief rest on a powered USB source usually restores recognition.

Questions about this item

How many charge cycles can the 1650mAh Li-Ion battery handle before it needs replacing?

The 3.6V 1650mAh Li-Ion pack is rated for typical lithium-ion cycle life; expect several hundred full cycles before capacity falls to roughly 80 percent, so a daily user usually swaps it every year or two.

What limits runtime first during a long shift — the 5.94Wh capacity or the 800mA charge rate?

The 5.94Wh capacity sets the runtime ceiling; the 800mA output only affects how fast a depleted pack recharges, not how long it powers the radio.

Does the LTD2 charger get hot or noisy when charging two batteries all day from a 5V 2-3A source?

The dual-slot LTD2 runs silently with no fan; it may feel warm during sustained 800mA x2 charging from a 5V 2-3A supply, but stays within normal operating temperature.
