1.5V Ultra alkaline battery LR6
Alkaline batteries are disposable batteries with zinc and manganese dioxide as electrodes. The alkaline electrolyte used is either potassium or sodium hydroxide. These batteries have a steady voltage offering better energy density and leakage resistance than carbon zinc batteries.

LR14 1.5V Ultra alkaline battery
Alkaline batteries have excellent longevity and a longer shelf life than batteries with a chloride-type electrolyte. Unused alkaline batteries can last up to seven years, losing just five percent of their energy per year.

Ultra Digital Alkaline Battery
An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide, nickel and cadmium, or nickel and hydrogen.
Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage.
