Guess wot happens when you leave batteries in stuff for 20 years.
Amazingly enough, only one out 5 Thandar counter/timers thingies is a write off coz of battery leakage.
But that one was a real goodie, I don't know what that yellow gunge is*, but I'm not touching it without gloves on.
But a set of Vart C cells with a best before of March 1989 are still going strong giving roughly an amp on short circuit.
All the duracell ones were either leaking or flat as the proverbial pancake**.
*probably potassium hydroxide.
** best before June 1993.
