3V LITHIUM BUTTON CELL / COIN BATTERY - GP

Coin-shaped cells are thin compared to their diameter. The metal can is the positive terminal, and the cap is thenegative terminal.

FEATURES:

  • Lithium Batteries are primary batteries with outstanding high-energy density
  • Voltage during discharge is about twice that of ordinary batteries.
  • The energy density is the highest among conventional primary batteries - 5 to 10 times higher than that of carbon zinc batteries.
  • These lithium batteries are able to operate at very low temperatures of around -20°C.
  • Extremely small voltage decrease and very stable voltage during operation.
  • CR denotes manganese dioxide lithium chemistry. Since LiMnO2 cells produce 3 volts there are no widely availablealternate chemistries for a CR coin battery. Conversely, one LiMnO2 cell can replace two alkaline or silver-oxide cells.
  • All these lithium cells are rated nominally 3 volts (on-load), with open circuit voltage about 3.6 volts. The IEC "CR" prefix indicates a round, lithium/manganese dioxide cell. Some sizes are also designated with a "BR" prefix, indicating a round lithium/carbon monofluoride cell.

Common Applications:

  • Electric wristwatches, both digital and analog.
  • Calculators
  • Hearing aids
  • Some remote controls, especially for keyless entry
  • Backup power for personal computer real time clocks and BIOS configuration data.
  • Small PDA devices
  • Various electronic toys (like tamagotchi, Pokémon Pikachu or a Pokéwalker and other various Virtual Pet devices.)
  • Laser pointers
  • Small LED flashlights
  • Battery-operated children's books
  • Glucometers
  • Security tokens
  • Cyclocomputers
  • Red dot sights and electronic spotting scopes
  • Manual cameras with light meters, such as the Pentax K1000
  • LED throwies
  • Various video game cartridges or memory cards where battery-powered RAM is used to store data.
  • PCMCIA static RAM memory cards
