Kastar M53615 Battery and LTD2 Charger Kit

This kit pairs a 1650mAh 3.6V Ni-MH battery with an LTD2 dual-slot USB charger. It is built for owners of compatible Motorola two-way radios who need a spare power cell and a way to recharge two packs at once from any 5V USB source.

Charger Input and Output Limits

The LTD2 charger accepts 5V at 2–3A through either Micro-USB or USB-C and delivers 8.4V or 4.2V at 800mA per slot when charging two batteries simultaneously. An integrated LCD shows real-time capacity and charging status for each bay.

Replaces Disposable Cells for Frequent Radio Users

The rechargeable pack replaces single-use batteries in supported Talkabout models, cutting waste and ongoing cost for teams that run radios daily. The jump is worth it when you operate multiple handsets and want a single charger that handles both packs without a wall-wart adapter.

Questions about this item

Should I pick the 1650 mAh Ni-MH pack or a higher-capacity option?

This listing only includes the 1650 mAh 3.6 V Ni-MH battery; no other capacities are offered.

What does the 5.94 Wh rating mean for my radio runtime?

At 3.6 V the 5.94 Wh cell delivers 1650 mAh, matching the original Motorola packs for equivalent talk time.

How does the USB Type-C and Micro-USB input limit charging speed?

The charger accepts 5 V at 2–3 A and outputs 8.4 V or 4.2 V at 800 mA per slot, so each battery charges at that rate regardless of the USB port used.
