Review on Synergy Digital Cordless Phone Battery - Compatible with Rayovac RAY77 Cordless Phone, High-Capacity (2.4V, 700mAh) NI-CD Battery by Tylin Meyer

This battery was designed for this Uniden phone, DECT 6.0 but didn't fit without adjustment. I like the width and depth of the battery because it fits snugly in the phone without moving like the last battery I used. Although the top is not pictured as new, the part that connects to the phone is not smooth on all 4 sides. I used a precision knife to shave the excess plastic off both sides of the connector. Also, when viewed from above, the plug has two curved sections on one side, while the socket is straight on all four sides. Luckily the round side still fits and works. I like the option to buy batteries and the phone works because it's cheaper than a new phone. There are 5 phones in this system and over time I have bought 4 batteries and expect to end up buying the 5th. Highly recommend for this phone.
