I was out today enjoying the nice weather, stopped for lunch. Went to start up and nothing, not a sound not any illuminations on the dashboard.

Called the A.A. They checked and said that the battery was not holding a charge and suggested that I replaced the battery. The battery that I have is 036 300amp heavy duty. I went to Halfords (AA kindly followed me) but they did not have this battery.

Whilst driving the speedometer needle was pointing to zero or the maximum above 140mph. The mileage counter was functioning but was adding two miles or so for each mile driven. The rev counter was stuck on 2.5.

I am not at all technically minded. Could the speedometer and rev counter be affected by the problem with the battery?

The Morgan will start using booster cables. So I was able to get home.

Is the battery that I have 036 300amp the correct one for the car? Should I replace it like for like? If so where could I source a replacement?

Any help greatly appreciated.

Cheers, Lol
