Lithium AA Batteries

• 1.5-1.7 volts approx xx mah
• primary battery, not rechargeable
• LiFeS₂ chemistry
• used for 1.5V AA applications (some devices have problems with the extra voltage)
• handle high current loads and low temperatures better than many other types
• known for light weight, extremely long energy retention, good for emergency standby service

• 3.6-3.7V approx 750 mah
• secondary battery, rechargeable
• more than double the voltage of a standard AA
• used in some LED flashlights that have voltage compliant regulators
• these are similar to the laptop batteries and occasionally catch fire
• do not charge improperly!
• do not overdischarge!
