About this replacement
Huawei F316 / F317 / F202 / F360 — 3.6V Ni-MH Replacement Battery (HNBAAA600-31)
This is a 3.6V, 700mAh Ni-MH replacement battery for Huawei cordless DECT handsets. It fits the F316, F317, F202, and F360 models. The OEM part number is HNBAAA600-31, and the cell dimensions match the original battery bay exactly at 45.15 × 31.25 × 11.43mm.
- F316, F317, F202, F360 fit group: These four handsets share the same battery bay dimensions, 3.6V rail, and base station charge circuit. A single cell pack works across all four without modification.
- Bench tested on actual hardware: We ran this pack through the Huawei base charge cycle and confirmed the charge circuit accepted the NiMH cells without triggering an error state. Voltage at end of charge measured within spec.
- First charge on NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless handsets need a slow initial charge to reach rated capacity — skipping this shortens talk time from the first day.
Talk time shorter than original battery after replacement
NiMH cells ship in a partially discharged, conditioned-for-storage state. The first two to three full charge and discharge cycles progressively unlock the full 700mAh capacity. Capacity measured on cycle one is typically 60–70% of rated. By cycle five, the pack should be at or near full rated output. Run the handset to low battery and return it to the base each time to complete a full cycle.
Base station showing no charge light after battery swap
A new NiMH pack coming out of storage can sit below the voltage threshold the base station checks before starting a charge pulse. Some Huawei bases will not initiate charging if the pack reads under approximately 3.0V. Remove the handset, wait 10 seconds, and reseat it firmly — this resets the charge detection cycle. If the base still shows no activity, confirm the contacts on both the handset and base are clean and making full contact.
