Fantastic battery. Fit the phone perfect. The great thing about this battery, was that it did not die due to the power outage. Every other battery I have purchased for this cordless phone would loose all of its charge as soon as the power went out due to storms. This battery did not. Our power was out for approximately eight hours the other day, and when it came back on, the phone worked without having to recharge it. I am not sure why this one holds the charge, but it’s fantastic.

The battery pack was very well packaged and was shipped promptly. It took about a day to fully charge, which is not unusual. It seems to be working just fine.

battery's are working well, know problems.

Replaced anther brand easily, installed with ease.

The original batteries on the old Uniden phone were only giving us a few minutes of talk time. We did receive the 1600mAh batteries, as pictured. The phones are now working like new. We are no longer getting the battery dying beeps while on the phone any more. Well worth the price, versus bying a whole new cordless phone set.

Too many of the batteries out there don't hold much juice and you have to buy more than one of them. This one is different..

Product advertised is a Kastar 1600mAh high-capacity battery. What I was shipped was a 900mAh Synergy Digital battery. So I returned the lower capacity battery, opting for them to exchange it with the actual product I ordered. But what I was sent the second time is another 900mAh battery. Both batteries were shipped in boxes labeled as the 1600mAh product. Based on other reviews, this doesn’t seem to be a fluke. Lower quality batteries are being put into high capacity battery boxes and advertised as 1600mAh.
