Alcatel Origin POP Cordless Phone Replacement Battery 2.4V 300mAh

Alcatel Origin POP / EU-016078 — 2.4V Ni-MH Replacement Battery

This is a 2.4V, 300mAh Ni-MH battery for the Alcatel Origin POP cordless DECT phone (also listed as EU-016078). It slots into the handset and powers the phone away from the base station. No OEM part number exists for this pack — compatibility is confirmed by voltage, footprint, and connector orientation.

• Origin POP and EU-016078 fit: Both model references point to the same Alcatel handset platform. The 2.4V two-cell Ni-MH configuration matches the handset's charging circuit and connector pinout — no adaptation needed.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a DECT handset rig. The BMS on the base station accepted the pack without fault indication, and voltage stayed consistent across the RF transmit bursts.
• First-charge protocol for Ni-MH cordless packs: After installing, seat the handset in the base for a full 16-hour charge before first use. Ni-MH cells in cordless phones need a slow initial charge to reach rated capacity — a quick top-up will leave the pack underperforming for the first several uses.

Alcatel DECT bases check incoming voltage before starting a charge cycle. A new Ni-MH pack shipped in storage can measure below 2.0V — low enough that the base reads it as a fault rather than a depleted battery. This is not a defective battery. Place the handset in the base, wait two minutes, remove it, then reseat it firmly. The base re-polls on contact and will typically begin charging once it registers the pack is present.

Range drops noticeably when the handset moves away from the base

DECT handsets boost RF transmit power as signal weakens — this draws more current in short bursts. When a Ni-MH pack is partially discharged or not yet conditioned, voltage sags under that load and the handset steps back its transmit power to compensate. The result is shorter effective range than the original battery. Run three to five full charge-and-use cycles to condition the cells to rated capacity, and the voltage sag under RF load will reduce. After conditioning, confirm the pack reaches at least 2.8V on the charger at end of charge.
