Replacement Battery for DECT & OpenPhone Handsets

This replacement battery fits Integral D3, OpenPhone 24, OpenPhone 28, D4 Office, DECT FC1Ex, FC1 and FC4 cordless handsets. It restores full talk and standby time when the original pack no longer holds charge. High-quality cells are engineered to meet or exceed the original specifications for reliable daily use. The pack is a direct drop-in replacement for the listed models.

Upgrading from a Worn-Out Original Pack

When an original battery shows reduced runtime, fails to charge fully or causes the handset to power off during calls, this unit replaces it without modification. The jump is worth it whenever the handset itself is still functional but the power source has degraded. No firmware updates or adapter cables are required for the swap.

Fits Standard Handset Battery Compartments

The battery slides into the existing compartment and connects to the factory connector, so no soldering or case alterations are needed. It frees the user from keeping the handset on the charger between calls. Compatibility should be confirmed against the model label before installation.
