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

Yes, I've been on the phone for a long time, but I expect the batteries to last more than a day before needing to be plugged into a charger. It looks like I used to be able to use it for at least a couple of days before the battery died. I'll try another brand to see if they're just Panasonic batteries or if they just made all the brands to hold less charge. I've tried Panasonic batteries twice, thinking the first one might just be defective, but the second set I bought wouldn't charge. I am very disappointed in this product.
