Happened to try a seldom-used tv remote control last night, dead.
opened it up, one 2013 AA Energizer battery was fine, the other was
dead and leaking. I stupidly thought that the date on batterries was
how long they were supposed to last if they were not used - shelf
life.

Since the battery was not used more than a few minutes since it was
put in the remote a couple of years ago, and had been in an air-
conditioned and heated room in the house for its entire time since I
brought it home from the store, I thought that it was safe to leave it
in the remote without having to periodically check for leakage.
Fortunately, the leakage was minor and because of the physical
position of the remote, the leakage went onto the inside of the back
cover and did not get into the electronics in the remote.

Just thought I would post it here as a reminder not to assume anything
about battery life.

Well I know it's a contentious thing to talk about which brand but we
have just stopped buying Eveready products because to us they are just
inferior to another popular brand in most ways, like endurance and
leakage etc. IMHO it is also a good idea to wipe the contact surfaces
with an oily rag or a thin smear of grease when installing batteries
that are used in flashlights and the like. Whilst it's hard to remember,
following most manufacturer's advice to remove the batteries if the
device is to be unused for long periods is sound :-)

Well, I could chime in here to point out that we have opened a number of
video and pinball games that were factory sealed since 1980 - and they
all contained either Royovac, Eveready Energizers, or Duracels as
battery backups for 5101 CMOS RAM. In a number of cases the batteries
(all brands) still had a charge, a few were still very close to 1.5VDC,
most were around 1.0VDC.
