[Test-Equipment] Test-Equipment Digest, Vol 111, Issue 10

Fri Jul 19 15:15:19 EDT 2013

One other thought. I work for my buddy who has a LOT of battery devices. He likes to replace them on a VERY regular basis, just 'cause he hates it when a electronic lock won't open!
I (not having bottomless pockets), keep my spare batteries in my shop 'fridge.
Good idea? Make any difference??

 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,

Wayne

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 agree, but the batteries that were worst were also sitting about with no load. 
I'm hoping experience has shown certain brands are better choices for forgetful 
folks like me who leave them in longer than we ought to.
