Replacement for Panasonic Ultraplex II

This Ni-MH battery pack replaces the Panasonic 2020BAT and PA04940398 cells used in Ultraplex II and WX-CT2020 handsets. It delivers 3.6V and 1500mAh capacity in a black housing that matches the original form factor.

Direct-fit design requires no adapter

The pack measures 56.23 x 47.11 x 16.16 mm and aligns with the factory contacts, so installation is a simple swap. No soldering, shims or firmware updates are needed to restore talk time.

Ni-MH chemistry limits charge speed

The 1.5 Ah cell accepts only a modest charge current, so a depleted pack takes several hours on the original cradle. Self-discharge is higher than lithium types, meaning stored spares lose usable energy within weeks.

Questions about this item

How many full charge cycles can the 1500mAh Ni-MH pack deliver before capacity drops noticeably?

Nickel-metal-hydride chemistry typically provides several hundred full cycles; actual life depends on depth of discharge and storage temperature.

What limits runtime during a long conference call on the WX-CT2020 headset?

The 5.40 Wh capacity sets the hard ceiling; continuous talk time will drain the pack until the headset signals low voltage.

Does the battery become warm or draw extra power when the headset runs all day?

Ni-MH cells stay cool at normal headset currents; no active cooling is needed and self-discharge is low when idle.
