3-Pack Ni-MH Batteries & Dual USB Charger

This set supplies three 3.6 V 1650 mAh Ni-MH batteries plus an LTD2 charger that powers two cells at once from any 5 V USB source. It fits Motorola Talkabout radios including the MR350R, MR355R, MR356R and many other listed models.

LCD Charger with Micro-USB and Type-C Inputs

The charger accepts Micro-USB or Type-C at 5 V 2–3 A and delivers 4.2 V at 800 mA per slot when two batteries are fitted, or 8.4 V at 800 mA for a single cell. An intelligent LED display shows charging status and remaining capacity during the cycle.

Compact Pack for Extended Radio Runtime

Three spare packs keep multiple handsets operating on long shifts or outdoor trips without needing a wall outlet. The bundle adds no AC adapter, so a power bank, vehicle port or laptop USB port is all that is required to replenish the cells.

Questions about this item

How do I install the Kastar M53615 batteries into my Motorola Talkabout MR350R radio?

Remove the battery cover on the back of the radio, insert each 3.6V 1650mAh Ni-MH pack with contacts facing inward, then snap the cover shut; the step often missed is aligning the notch on the pack with the ridge inside the compartment so the latch engages fully.

What maintenance will the LTD2 charger and the three 5.94 Wh packs need over time?

Wipe the charger's Micro-USB and Type-C ports with a dry brush every few months, store the 1650mAh packs at roughly half charge if unused for weeks, and replace any pack that no longer reaches the 8.4V/4.2V 800mA charge indication on the LCD.

What limit appears first when I charge two 1650mAh packs simultaneously on the LTD2 charger?

The charger drops to 800mA total shared across both bays, so each 3.6V pack charges at half the single-bay rate, extending the full-charge cycle compared to charging one pack alone.
