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
