Review on High-Quality Panasonic Genuine HHR-4DPA/4B AAA NiMH Rechargeable Batteries for DECT Cordless Phones, 4 Pack – Long-lasting Power Solution! by Robert Carter

I bought my Panasonic phones a few years ago. I've replaced other cordless phones whose batteries didn't last long. At that point I had to put them on the charging station every 3-4 days even if they weren't being used, otherwise they would die. The new Panasonic phones were amazing. They held a good charge for several weeks before needing to be placed on a charging station. 2 weeks later at the latest. Probably 3 weeks in many cases. Batteries gradually lost this ability over the years, eventually needing to be recharged every 4-5 days. Instead of buying all new phones again, I decided to replace the failed batteries with new OEM batteries made for these phones. Results? Very disappointing. I was expecting to be recharged for at least 2-3 weeks. Instead I get about a week. So it's better than 4-5 days but nowhere near as good as I expected or hoped. They are a slight improvement on batteries that have been used for 4-5 years.
