Battery Panasonic HHR-4XXE/2BC
The Panasonic HHR-4XXE/2BC rechargeable battery is designed for use in compatible Panasonic cordless telephones such as KX-TG6811 and KX-TG6812. Built with Nickel-Metal Hydride (NiMH) chemistry and a nominal voltage of 1.2 V, this replacement battery delivers steady power to maintain call quality and handset readiness. Supplied in a blister pack, the battery is intended for straightforward installation and safe everyday operation in supported phone models.
NiMH construction provides stable discharge characteristics and reduced memory effect compared with older rechargeable types, allowing reliable performance during typical cordless phone usage. The nominal 1.2 V rating matches handset requirements for consistent operation. The compact form and blister packaging make the battery simple to handle and replace, while compatibility with multiple Panasonic models reduces the need to search for model-specific cells.
Before replacing the battery, power off the handset and remove it from the base. Open the battery compartment according to the handset manufacturer’s instructions, remove the depleted cell, and insert the new Panasonic HHR-4XXE/2BC battery observing polarity markings. Close the compartment and place the handset on the charger base to perform an initial full charge if required by the handset. Follow the cordless phone user manual for any specific charging cycles or calibration steps.
Charge the handset after installing the new battery and allow a full charge cycle when practical. Avoid exposing the battery to extreme temperatures and follow handset manufacturer guidance for safe disposal or recycling of NiMH batteries.
