MAXELL Watch Battery - SR421SW

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.

Chemistry: Silver Oxide
  • Voltage: 1.55V
  • Capacity: 12mAh
  • Diameter: 4.8 mm
  • Height: 2.15 mm
  • Low Drain Type - Best used with analog watches
  • A flat discharge curve during discharge supplies a stable voltage until the end of the discharge life
  • High-energy density per unit volume provides 2x the amount of energy capacity as button-type alkaline batteries
  • Featuring Maxell's original leak-resistant processing
