SpectraLink BPE110 Replacement Battery 3.6V 700mAh Ni-MH

SpectraLink BPE110 / E340 / H340 — 3.6V Ni-MH Replacement Battery (A0548446)

This is a 3.6V, 700mAh Ni-MH battery for the SpectraLink BPE110 cordless handset and compatible models including the E340, H340, and i640 series. It replaces OEM part numbers A0548446, BPN100, NTTQ69BA, NTTQ4050, and PTE110. Drop the handset back in the base cradle and you're back on the wireless network.

• BPE110 / E340 / H340 / i640 platform fit: These handsets share the same 3.6V single-cell Ni-MH form factor, cradle contact layout, and charge management circuit. One battery SKU covers the full group because the base station's trickle-charge profile is identical across the range.
• Bench tested on actual hardware: We cycled this cell through the SpectraLink base station charge circuit and confirmed the BMS accepted the pack without error, reached full charge voltage, and held standby current within spec across multiple charge-discharge cycles.
• First-charge protocol for Ni-MH handsets: Place the handset in the base cradle for a full 16 hours before first use. Ni-MH cells shipped in partial-charge storage need a slow initial charge to reach rated 700mAh capacity — skipping this produces noticeably shorter talk time in the first few cycles.

SpectraLink base stations use a delta-V detection method to confirm charging. If the incoming battery voltage is too low from storage, the base may not register a valid Ni-MH pack and will flash an error or show no charge activity at all. This is a threshold issue, not a fault with the battery. Place the handset in the cradle and leave it undisturbed for at least two hours — the base trickle-charges below the detection threshold first, then steps up once the cell reaches roughly 1.1V per cell.

Talk time noticeably shorter than the original battery after replacement

Ni-MH cells do not ship at full capacity — they typically deliver 60–70% of rated capacity on the first cycle. The BPE110 handset does not run a conditioning routine automatically, so the first two or three charge cycles will feel short. Each full charge-discharge cycle builds toward the rated 700mAh. By cycle four or five, talk time should match or exceed the original battery. If it does not improve after five full cycles, confirm the handset is sitting flush in the base with clean cradle contacts.
