My TR 3A battery usually goes flat and after a night charge it lasts a couple of days. But this last month the charge will not last long. It was new in 2014 so it has done well. I am going to Halfords on Tuesday for a suitable battery with the terminals correctly placed at the back.
But I have started looking at the rest of the house. My watch stopped last week and a new battery came by post in 36 hours.
