🔋 High-performance Empire Cordless Phone Battery 1X3AAA/D - 3.6V Ni-MH 700mAh - Direct Replacement Battery Review

These are the worst batteries ever. I've replaced 3 of my phones and none of them hold a charge - crap don't buy them. They are produced under the name synergy digital made in China.

Arrived on time. The battery fits my phone as expected. So far I have used the phone once with a new battery and it works without any problems.

Functions as a replacement battery for the Slendertone waist belt; All you have to do is line up the nail file with the small plastic clip so it fits into the controller. I didn't even pay much attention to it, just filed it until it fit and now my 10 year old Slendertone works like new. Much cheaper than the official Slendertone battery available on their website.
