Just a curious question. Right forum ?
Portable Radios. Batteries.
It is ancient knowledge not to leave batteries in a radio BUT does it really mean anything these days ?
I had a couple good dx portables destroyed by batteries left in them. Did not just eat the battery compartment.
BUT recent times I have not heard much about the subject. Nobody wants to take the batteries out every time you set a radio down you are using.
Do they make batteries better now ?
Just a warning. 2 of my brand new C Cranes I put to the aside for a month or so and I open the battery compartment to look and what

!!!!! It's like somebody poured brown water in there. (maybe they did)
Batteries tarnished and wet and battery case some liquid brown. I hope I caught it before it ate the radio or simply made it not work forever.
What the H do they put in a battery that would result in such ?
NOW the problem has been with DOLLAR TREE batteries. (Sunbeam?) A cheap solution if you have these stores all around you. I never saw a battery put out liquid so fast. Also recent checked voltage of new ones at the store and they flunked with the battery tester. These are the general purpose ones. I have had luck with the alkaline if you can find them.
