This Panasonic HHR-P104 cordless phone Ni-MH battery has an integrated microchip that prevents overcharging and lengthens battery life.

This battery is a direct replacement for your cordless phone battery that can no longer hold a proper charge or loses its charge quickly. Keep an extra battery on hand for when your handset loses power and you do not have time to recharge the drained battery before using your phone again.

    These batteries do not last very long before they have to be recharged. I couldn't find a date on them, but from the way they don't keep a charge, I would say that they are very old, or had been stored in a very warm place.

    Excellent and fast delivery. We have three portable phones using these batteries and all three started to fail at the same time after being in serve for 4 years. This was the best price for the exact replacement battery.
