what does the alphabet "A" represent / mean (with regard to battery sizes) ?

Does it stand for "alkaline"?


Well....no.

The alphabetical system originates from the physical size, not the chemistry (alkaline). One of the first portable power cells was termed an “A” cell. Subsequent cells that were introduced were larger (C, D) or smaller (AA, AAA, AAAA) and were termed as variations off of the “A” cell. Alkaline was not formally introduced to consumers until the 1960’s and only became the dominant chemistry for the standard sizes in the late 1970’s, long after the physical sizes were established in other chemistries like carbon zinc (general purpose) or zinc chloride (heavy duty).

When it comes to battery exploding - I trust Duracell

When my wireless keyboard, mouse or my wall clock are thirsty for Alkaline liquid, I trust Duracell......

I really don't understand why this has been happening to me very frequently. And only with Duracell.
3 Batteries exploded or should I say "vented" in my equipment within a year.
This batteries were purchase in the US at stores like Wal-Mart and came from three different packages. Two batteries were AA and one AAA. The company always seems to say that this is due to counterfeit product from china. Well, Wal-Mart sells a lot of stuff from china but if they sell counterfeit Duracell product....Duracell gotta start to worry.

The scariest was on my wireless mouse. the batteries just popped while in use and it really scared the hell out of me.

I have been using brands like Rayovac, Werker, Energizer without having any problem ever ever ever.

Does keeping batteries in a Refrigerator preserves their lifetime?

We've all heard that but in fact, it is not really recommended. Batteries should be stored in a dry location at room temperature. Storing at a lower temperature will decrease the natural/self discharge of a battery, but generally it is not recommended since the high humidity levels inside of the refrigerator can cause the battery cell container and terminals to rust. If you currently have batteries stored in a refrigerator, be sure to allow them to warm up to room temperature before using them in your device.
