Four-pack batteries with dual USB charger

This set supplies four replacement Li-Ion cells and an LTD2 charger for Motorola TalkAbout two-way radios. The pack targets users who need spare power for extended outdoor or professional use. Each cell delivers 3.6 V and 1650 mAh capacity. The charger accepts Micro-USB or Type-C input and powers two batteries simultaneously.

Replaces original Motorola packs across many models

The batteries match the 53615, PMNN4477 and HKNN4002 series used in TalkAbout T5710 through T5950 radios. Swapping to this kit is worthwhile when original cells no longer hold a full day’s charge. The charger’s LED display shows individual status so you can rotate cells without guesswork.

Fits existing radio fleet with no extra hardware

The charger draws 5 V from any USB power source, removing the need for a dedicated wall adapter. Its compact size stores easily in a gear bag or vehicle console. Four cells let you keep two radios running while the other pair recharges, eliminating downtime during shifts or trips.

Questions about this item

What are the exact dimensions of each 1650mAh Ni-MH battery so I can confirm it fits my radio's compartment?

Each battery measures 50.29 x 42.4 x 14.37mm (1.98" x 1.67" x .57"), matching the original Motorola 53615 form factor.

How do I correctly insert batteries into the LTD2 charger's dual slots to avoid a charging error?

Align the battery contacts with the charger pins; the intelligent LED display shows status for each slot independently when 5V 2-3A input is applied.

When should I replace the four 5.94 Wh Li-Ion packs if runtime drops noticeably?

Replace them when the charger's LCD capacity reading stays low after a full 8.4V/4.2V 800mA cycle, indicating cell degradation.
