[Test-Equipment] VOM Batteries that don't leak?

[eric lemmon]

Wayne,

I think the Radio Shack batteries lasted as long as they did simply because
they had zero load during storage.  The batteries (cells, actually) that
leak very often have a very low but continuous load on them, such as a
clock, or a portable radio that has an internal time chip.  The best
insurance is to replace batteries on a calendar basis, and to remove
batteries from devices being stored for more than a few weeks.

 I've been replacing several VOM & VTVM batteries this week and found some
that were trying to consume themselves. But to my surprise, one of the old
batteries was a Radio Shack Enercell dated 1999 that not only showed no sign
of leakage but still measured 1.55 volts. 

So, I said to myself, "Self! Go tomorrow and buy more Radio Shack Enercell
Extra Life batteries with the 'Miracle Seal.' (Miracle Seal is printed right
on the battery.) But guess what? I look online indicates they don't sell
them anymore!

So my question is whether any of you have recommendations for A, C and
9-volt batteries that have a good reputation of not making a big mess when
they have been left in place past the expiration date?

Thanks & 73,
