Overview

The Panasonic HHR-P104A is an OEM Nickel-Metal Hydride replacement battery designed specifically for Panasonic cordless telephones that accept a Type 29 battery. As a genuine Panasonic part, it matches the original battery's voltage, capacity, and connector specifications, ensuring a seamless fit and reliable charging in your phone's cradle. NiMH chemistry offers a stable voltage curve through most of the discharge cycle, meaning call quality and phone performance remain consistent until the battery signals it needs recharging.

Installation is simple—open the battery compartment on your cordless handset, disconnect the old battery, plug in the HHR-P104A connector, and return the handset to its charging base. The three-letter code printed on the battery is a production lot identifier and does not affect compatibility. For households still relying on Panasonic cordless phone systems, this battery provides a cost-effective way to restore talk time and standby performance without replacing the entire handset.
