This is a "SW" low drain battery. Low drain batteries are best used in devices that use a small amount of power over a long period of time: Analog watches, TV remotes, alarm clocks, etc. This is in comparison to high drain batteries, which are for devices with a continuous, low power use and occasional high peaks: Analog and digital watches with extra functions (backlight, alarm), pocket calculators, electronic games, cameras, etc.
