Synergy Digital Cordless Phone Battery, Compatible with Panasonic KX-TG4731 Cordless Phone, (Ni-MH, 1.2V, 1000 mAh) Ultra Hi-Capacity Battery

What I ordered arrived when I expected, seem to be working just fine.[added remark]Several phones (most used) in the 6-instrument system had started showing erratic battery behavior (some had never in 10+ years gotten new batteries, I think).Replaced all 12 cells with these--no further erratic behavior. I don't know what life to expect from these, but if I am still alive when they again show signs of fatigue I will replace the lot again with cells like these.

The talk time on my old batteries was getting really short, the new batteries revived them to as good as new. Very Happy with them.

I was very, very disappointed when I got my phone batteries , they still did not work . What's going on here?

Probably just as painless a purchase I’ve made in a bit. Prompt delivery reliable product and came fully charged.

Ok, it's a battery, yes NiCad but this is what my phones want. So far so good, hold a good steady charge.

Really a great battery for my Panasonic phones and at this time they are holding their charge and working great. I am going to buy more for our additional phones.

Perfect fit. Batteries last longer per charge than any others I have used. Highly recommend

used these to regenerate our land line phones. They were delivered promptly and are working great!
