What LR/SR Means
LR/SR is a pair of abbreviations that refer to different types of batteries. Silver Oxide is abbreviated as SR, and SR batteries are silver oxide batteries.
The discharge curve of an SR battery is flatter than that of an alkaline battery, which means it has a longer run time. This is a significant advantage over some other types of batteries.

An SR battery is also referred to as an LR Button Battery, and it has no flammability issues. This makes it a safer choice for certain applications.
LR, on the other hand, is an abbreviation for a round alkaline battery, which is used in LR41 batteries. These batteries are alkaline zinc manganese batteries.
The ideal temperature for LR41 batteries is 20°C, making them suitable for use in a variety of environments.
