[Boatanchors] VOM Batteries that don't leak?

[David Knepper]

The question, gentlemen, is to discover why batteries leak?


Nowadays all batteries are "leak proof" and have a metal case around the 
cardboard jacket and this considerably reduces the risk of leaking and 
batteries will not leak until they have been discharged well beyond any 
useful level but if you leave discharged batteries inside a unit or 
accidentally discharge them totally by leaving something switched on they 
will leak electrolyte.

All the batteries seem to be chinese garbage now.
I use a lot in test equipment, and all the types I've tried
will leak even before their expiration date
if they get a little hot, like in a truck tool chest.
The advice to remove batteries if you're going to shelve
a piece of test gear for even a few days is sound,
especially now.
If someone knows of a decent brand, I'd also be interested.
