MBO Dialon F10 Cordless Phone Compatible Battery 3.6V 320mAh

MBO Dialon F10 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 320mAh Ni-MH rechargeable battery for the MBO Dialon F10 cordless phone handset. It restores wireless operation when the original cell no longer holds a charge. Dimensions are 30.00 x 32.00 x 10.50mm — confirm these against your existing pack before ordering.

• Dialon F10 handset fit: The Dialon F10 uses a low-capacity single-cell NiMH pack on a 3.6V rail. This replacement matches that voltage and physical footprint, so the handset closes correctly and makes contact with the charging pins.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a NiMH-compatible charger and confirmed the BMS accepted the cell and delivered stable voltage through the handset's standby and talk states.
• First-charge requirement for NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells ship partially discharged — skipping this slow initial charge means the cell never reaches rated capacity and talk time will disappoint from day one.

Talk time shorter than original battery after replacement

NiMH cells need three to five full charge-discharge cycles before they hit rated capacity. A new pack straight out of packaging will underperform the original for the first few days — this is chemistry, not a fault. Each full cycle lets the cell's crystalline structure settle and increases usable capacity. Run three complete cycles through the base station before drawing any conclusions about talk time.

Base station showing no charge light after new pack installed

NiMH packs sitting in storage drop below the voltage threshold some base stations require before they begin a charge cycle. If the base shows no light or an error state, the handset may need a brief top-up from an external NiMH charger first — just enough to bring the cell above 3.2V. Once above that threshold, reseat the handset in the base and the charge circuit should recognise it and begin normally. Check the base pins are clean and making firm contact with the handset terminals.
