Compatible Radio Power Kit

This pack supplies two rechargeable Ni-MH batteries and a dual-slot USB charger for a wide range of Motorola TalkAbout two-way radios. It is intended for users who need reliable backup power for outdoor, recreational or light professional communication. The kit replaces original battery packs such as the 53615, 1532 and 56315 series used in many TalkAbout models.

USB Charging Limits

The LTD2 charger accepts power through either a Micro-USB or USB Type-C port at 5 V, 2–3 A input. It can charge both batteries simultaneously at 800 mA each, or a single battery at 800 mA with an 8.4 V or 4.2 V output. An integrated LED display shows charging status and remaining capacity for each cell. No AC adapter is included, so a suitable USB power source must be provided separately.

Battery Capacity Decides Fit

Each cell delivers 3.6 V and 1650 mAh for a total energy rating of 5.94 Wh, matching the specifications of the original Motorola packs listed in the compatibility table. Radios requiring a higher capacity or a different chemistry will not achieve their rated run-time with these units. The physical dimensions of 50.29 x 42.4 x 14.37 mm must match the radio's battery compartment exactly.

Questions about this item

Should I pick the two-battery pack or a single battery for my TalkAbout T5420?

The pack includes two 1650 mAh Ni-MH batteries and one LTD2 charger, so you can run one radio while the other cell charges.

What does the 1650 mAh rating mean for talk time on a T5600?

At 3.6 V and 1650 mAh the cell stores 5.94 Wh, giving several hours of typical transmit/receive cycles before a recharge is needed.

How do the Micro-USB and Type-C inputs on the LTD2 charger affect charging speed?

The charger accepts 5 V at 2–3 A and delivers 8.4 V or 4.2 V at 800 mA per slot, so both inputs charge two batteries simultaneously at the same rate.
