Motorola NNTN8117A Single-Unit Charger Base for MOTOTRBO Radios

Fleet managers running MOTOTRBO XPR, DP, or DGP series radios need a charger base that accepts the battery without adaptation and signals charging status clearly. The NNTN8117A uses guided side rails and direct contact pin engagement to seat the battery or radio-with-battery correctly – the same mechanism used across the MOTOTRBO platform. There is no secondary adapter tray, no alignment guesswork, and no ambiguity about whether the battery is properly seated: a blinking red LED confirms detection within seconds of insertion.

The NNTN8117A handles the full authorized battery chemistry range for MOTOTRBO - NiMH (PMNN4065, PMNN4104, PMNN4412, PMNN4415) and Li-Ion including IMPRES variants (PMNN4066, PMNN4077, PMNN4407, PMNN4409, PMNN4413, PMNN4448, and others listed in the authorized battery table). This single-base design eliminates the need to stock chemistry–specific chargers in a mixed-battery fleet.

The charger detects battery type and adjusts accordingly, with the LED color sequence indicating slow-charge, fast-charge transition, and completion states. Green blink – power-up, blinking red - battery detected / charging, blinking yellow - charge pending – battery too hot, cold, or over-discharged, slow green blink – NiMH slow-charge / Li-Ion above 90%, solid green - NiMH charge complete / Li-Ion above 95%

For facilities running multi-shift operations – manufacturing floors, security operations, event venues, or logistics hubs – the NNTN8117A is also field-serviceable in the sense that the base unit itself is non-repairable and designed for replacement rather than maintenance, which simplifies fleet management: a failed base is swapped, not diagnosed.
