Four-pack Li-ion batteries with dual USB charger

This set includes four 3.6 V 1650 mAh Li-ion batteries and an LTD2 charger that powers two cells at once. It replaces Motorola batteries such as PMNN4477, NNTN4384 and KEBT-071F. The pack suits teams that keep multiple Talkabout radios ready for daily use.

Charger runs from any 5 V USB source

The LTD2 unit accepts 5 V at 2 to 3 A and delivers 8.4 V or 4.2 V at 800 mA per slot. An LED display shows charge status and remaining capacity for each battery. No separate AC adapter is required, so the kit works from power banks, vehicle ports or wall adapters already on hand.

Only compatible with the listed Motorola Talkabout

The batteries fit radios including the T200, T460, T600 H20, T800 and T92 H2O series shown in the compatibility list. They will not work with radios that use a different form factor or voltage. Check your radio’s battery code against the supported part numbers before ordering.

Questions about this item

How do I install the batteries in the LTD2 charger, and what step do people often get wrong?

Insert each battery so the contacts align with the charger slots; the common mistake is placing a battery backwards, which prevents the LED status from lighting.

What maintenance or replacement will the 1650 mAh Ni-MH batteries need later?

After several hundred charge cycles the 3.6 V packs lose capacity; replace all four when talk time drops noticeably below the original runtime.

What limit shows up first when the charger runs two batteries continuously from a 5 V 2 A source?

The 800 mA per-slot output becomes the bottleneck, so both cells charge at the same rate instead of the faster single-bay 800 mA mode.
