What does LR mean on a battery?

"LR" on a battery is a code used to describe the type and shape of the battery. Here’s a detailed explanation:

1. L - Alkaline Chemistry
   The "L" stands for alkaline, which refers to the type of electrolyte used in the battery. Alkaline batteries are popular because they last longer, have a stable voltage, and are cost-effective compared to other types like carbon-zinc batteries. They are commonly used in everyday devices.

2. R - Round Shape
   The "R" stands for "round," indicating the battery has a cylindrical or button-like shape. This is standard for many small batteries used in electronics.

3. LR Code in Naming
   The LR code is part of a naming system to identify specific alkaline battery sizes. For example:

• LR44: A small, round alkaline button cell often used in calculators, watches, and toys.

• LR6: Another name for the common AA alkaline battery, used in flashlights, remotes, and cameras.

The "LR" marking helps users, manufacturers, and retailers identify the battery’s type and ensure compatibility with devices.
