About this replacement
Motorola Talkabout T6000 Series — 3.6V Ni-MH Replacement Battery (56318 / NTN9395A)
This is a 3.6V, 700mAh Ni-MH battery for the Motorola Talkabout T6000, T6200, T6210, and T6220 series walkie-talkies. It replaces OEM part numbers 56318 and NTN9395A. The pack fits the standard battery bay on these handheld two-way radios and uses the same contact layout as the original.
- T6000 series platform fit: The T6000, T6200, T6210, and T6220 all share the same battery bay geometry and three-contact interface. Voltage rail and connector position are identical across this family, so one pack covers the full group without adapter modifications.
- Bench tested on actual hardware: We cycled this pack through full charge and discharge on a T6200 unit. The BMS accepted the dock handshake on first insertion, held steady voltage through transmit spikes, and showed no premature cutoff under sustained PTT presses.
- First-insertion contact check on Talkabout docks: If the dock shows a fault LED when you seat this pack for the first time, remove it, wipe the gold contact strip with a dry cloth, and reseat firmly. The Talkabout charging dock requires a clean contact cycle to register the new BMS before charging begins.
Why the Talkabout T6000 cuts out mid-transmission on a new battery
When you press PTT, the radio draws a short current spike to power the RF transmitter. A Ni-MH cell at storage voltage — typically around 1.15V per cell — can trigger the BMS overcurrent threshold during that spike before the cell has warmed up through a charge cycle. The radio interprets the brief voltage dip as a fault and drops the transmission. Running a full charge cycle before first use brings cell voltage up to the 1.2V–1.25V operating range and eliminates this behaviour.
Bar indicator showing one fewer bar than expected after fitting a new pack
The Talkabout series uses voltage-threshold bar indicators, not a fuel gauge chip. A new pack shipped at storage voltage reads lower than a freshly charged cell, so the radio may display one or two bars even straight out of packaging. This is not a faulty cell. Charge the pack fully in the dock first — once cell voltage reaches approximately 1.42V per cell at charge completion, the indicator will reflect the correct level on next power-on.
