These batteries work super good in my old Panasonic cordless phones - Updated :(
Edit: I take it back, these batteries are more like average. When I charge these batteries up & put them in my phone they hold the 3 bar charge status like 50% longer than other batteries (that's good), but then they drop through 2 bars and 1 bar faster than other batteries and go dead pretty fast (not good). Most other batteries that I've tried drop through the 3 bar charge status pretty fast, but then they are slower to drop through 2 bars and really slow to drop through 1 bar and go dead & that is good because it means that the phone is still working even when the battery has been low for a while. Whereas, with these batteries, when your batteries get low, which they do & pretty fast, watchout or your phone will go dead faster than you expected. End Edit I have some old Panasonic NiMH cordless phones, and I have tried more than a few different batteries for these phones over the years. The only batteries that work really well and have a charge that lasts a long time, that I have found so far, are these Panasonic batteries. I will go so far as to say that they blow the competition out of the water (so to speak). They cost more but IMHO they are well worth it. Read more
