GP Lithium Battery 3V 75 MAH for Calculators- Hearing aids-watches- PDA devices

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
