Battery and charger for Motorola Talkabout radios

This pack supplies a single Kastar M53615 lithium-ion battery and an LTD2 dual-bay USB charger. It is intended for owners of compatible Motorola Talkabout two-way radios who need a replacement cell and a way to recharge it from any 5 V USB source.

5.94 Wh Li-Ion cell replaces Motorola 53615 series

The battery delivers 3.6 V and 1650 mAh in the 53615 form factor, matching the voltage and capacity Motorola specifies for the listed Talkabout models. The charger accepts one or two cells simultaneously and shows charge level on an integrated LCD.

Charger draws 5 V at up to 3 A from Micro-USB

Each bay outputs 4.2 V at 800 mA when charging one battery, or 8.4 V at 800 mA total when both bays are occupied. No fan is present, so operation is silent and heat output is minimal during normal charging cycles.

Questions about this item

How long will the 1650 mAh battery last in a Motorola Talkabout T480?

What does the 8.4 V and 4.2 V output on the LTD2 charger mean for charging speed?

The charger delivers 800 mA at 8.4 V for one battery or 800 mA at 4.2 V each when two batteries are inserted, so charge rate is fixed.
