Review on 🔋 Panasonic HHR-75AAA/B-10 Rechargeable Battery for Cordless Phones, 700mAh (Pack of 10): Long-lasting Power Solution by Angel Serafini

These batteries are advertised as rechargeable Panasonic AAA Ni-MH batteries for replacement in Panasonic cordless phones. When I first put these batteries in my phones, they seem to charge, but after a few hours, the message "Use rechargeable batteries" pops up on the phone screen. I've been trying to use these batteries for the past 6 months but have found that they last 10-15 minutes at best. Original Panasonic batteries held a charge for at least 60-90 minutes. I have since replaced these batteries and the phones are working perfectly. My conclusion is that these are not Panasonic batteries, but some kind of counterfeit. Don't waste your money and time with these batteries!
