GP 3V 550Mah Lithium Battery GP Typical Capacity: 610-620 mAh

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

• 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.

• 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
