batteries

Just verified that the Panasonic rechargeable batteries, HHR-4DPA, work as replacements for the HHH-55AAABU batteries that originally came with the phone (model KX-TGA101). Both are AAA sized and 1.2 V, but the 4DPA are 700 mAh while the 55AAABU are only 550 mAh.

You probably can find cheaper, but these qualify for Amazon’s free Super Saving shipping if your order is over $25.
