My old TI-52 calculator turned up a few weeks ago, it had been in an unopened packing box through several house moves. I was pleasantly surprised when I turned it on and it worked perfectly. This calculator was bought in 1986 and was used heavily for a couple of years at the office before moving home, it still has the original batteries (A76 RW62) which look to be in perfect condition.

In my business we supplied 'Procell' batteries with our equipment for many years without problems then found that the distributor started to complain about the poor batteries that we were fitting, they seemed to have much shorter life and there were reports of leakage..... We always fit Energizer batteries now, these seem to be of much better quality, for now anyway......
