I was going through some of my cable tracers yesterday to see which ones still had the batteries installed and found one of my Aegis CZ-1000 tracers completely dead, the probe was fine and uses a 9 volt battery but the oscillator uses two AA's, these happened to be Toshiba alkalines both marked as best before 2009, the battery tester shows one is working as good as new and the other is completely dead, like nothing at all. Anyway, they didn't leak
...and I don't ever remember seeing a leaky Toshiba battery, plenty of Duracell Procells and those Dick Smith Digitors but never a Toshiba.
Recall City: yes, I'll vouch for Toshiba alkaline batteries too
never had one leak even when flat and forgotten
Never had any smoke detector issue with them either, they were cheap to buy and just worked till I swapped them out every 6 or 12 months,
and put the used ones in multimeters or other gadgets etc.
I still have a pair of red style 9v Toshiba that are dated 2003-ish, used, and still show 8.4 volts under load.
No leaks, corrosion and will serve fine in a multimeter in a pinch.
fwiw I had the same positive experience with Tandy/Realstic? 9v batteries too.
Not sure if the current Toshiba battery line can perform half as well, but I'd buy them exclusively if they do,
but not holding my breath on that one...
