Maxell Silver Oxide Watch Battery SR421SW Low Drain Replaces 348 SB-A6

The 348, or SR421SW, is a popular Silver-Oxide cell commonly used in watches, with a shelf life of 5+ years. Other applications may include calculators, film cameras, medical instruments, cash registers, or FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors).

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.
