Verizon Wireless Home Phone LVP2 Replacement Battery 3.6V 2000mAh

Verizon Wireless Home Phone LVP2 — 3.6V Ni-MH Replacement Battery

This 3.6V, 2000mAh Ni-MH battery fits the Verizon Wireless Home Phone LVP2 base station. The LVP2 delivers landline-style phone service over a cellular network, and this battery provides backup power when mains power drops. Swap it when the original no longer holds charge through an outage.

• LVP2 backup power role: The LVP2 draws from this battery only when AC power is lost. The cellular modem and POTS emulation circuit both pull from the same cell, so a degraded battery trips the low-voltage cutoff faster than most users expect — often within the first minute of an outage.
• Bench tested on actual hardware: We cycled this cell through repeated AC cutoff events. The BMS held the 3.2V floor consistently and returned to float charge within the expected window after power was restored.
• LVP2 storage between outages: The LVP2 trickle-charges this battery continuously. If the base station is unplugged for extended periods, the Ni-MH cell self-discharges at roughly 1–2% per day — reinstall and leave on AC power for at least 16 hours before relying on backup operation.

Why the LVP2 drops the call seconds after a power outage starts

When AC cuts out, the LVP2 immediately switches load to the internal battery. The cellular modem and the POTS emulation circuit draw simultaneously — that combined spike can pull the cell voltage below the BMS cutoff threshold if the battery has degraded. A Ni-MH cell past 300–400 shallow cycles loses enough capacity that the voltage sag under this dual load is enough to trigger shutdown. Replacing the battery resolves this; a healthy cell stays above 3.2V through the startup surge.

LVP2 shows full charge indicator but dies immediately on outage

Ni-MH cells develop a voltage plateau that can fool a simple charge indicator even when usable capacity has dropped significantly. The LVP2 reads terminal voltage to display charge status — an aged cell sitting on trickle charge measures near full voltage at rest but collapses under load. This is called voltage depression, and it's common in Ni-MH cells kept in continuous trickle-charge applications. If the base station loses call within 30 seconds of an outage, replace the battery and measure resting voltage after a full 16-hour charge — a healthy cell reads 3.6V or above.
