Review on 6-Pack iMah AAA Rechargeable Batteries 1.2V 750mAh Ni-MH - Compatible with Panasonic Cordless Phone Batteries HHR-55AAABU (1.2V 550mAh) and HHR-75AAA/B (1.2V 750mAh) - Ideal for Toys, Outdoor Solar Lights, and More by Carmen Morris

I needed two batteries for an extra cordless phone I bought for my Panasonic expandable home wireless phone system. The extra phone was refurbished and came without batteries so those batteries worked great. It was already charged, so I quickly made sure my phone worked with my system and started charging on the stand. The 6 pack was a great deal so I thought I would get extras in case my original phones needed to change batteries. I've been using them for over a month now and they're working great so far.
