Where can I buy this battery near Macclesfield

On the underside of the programmer casing, and 2cm from its right side, is a catch that needs to be pushed up, using the blade of a screwdriver. The entire programmer case is then tilted upwards, and it detaches from the two locating lugs (topend). The battery is located on the inside of the main body of the programmer.
