There are acidic batteries and alkaline batteries. For example, car batteries are acidic and pen torch batteries are alkaline.
The two common types of batteries are alkaline batteries and non-alkaline batteries. Various experiments have proven that alkaline batteries last longer than non-alkaline batteries.
Alkaline batteries last longer than carbon-zinc batteries
I use alkaline batteries in my Olympus 2009 camera.
Regular Alkaline batteries are not designed to be charged. Charging of these batteries can be possible but this process is dangerous and may cause the batteries to explode or leak.
Alkaline dry cells last longer because NH4Cl, an acid found in non-alkaline, is replaced with KOH or NaOH, a base found in alkaline. The Zinc in an alkaline dry cell batteries tends to corrode less in basic conditions.

Because there the chemical inside the battery is alkaline!
NiMh batteries perform better in high discharge devices (like digital cameras) than alkaline batteries. They are also rechargeable, unlike alkaline batteries.
