My gas fire has a plastic box with 4 AA batteries - alongside each other - the lead out is via the press-stud arrangement that is the same as found on a 9volt PP9 battery. The plastic has succumbed to the heat and the pressure of the contact springs so I need a new one. I have looked on Maplins site and they don't seem to have one with the same (all lying flat) configuration which I need to enable it to stow in the recess.
Any other sources you can recommend?
