Etinesan Lithium AAA



Official specifications:

• 15-year shelf life
• Real Capacity: about 1100mAh

This is a Chinese brand of lithium AAA batteries.











As usual lithium is better than alkaline when delivering power, the capacity do not drop significantly with load and the voltage is higher.









Conclusion

These cells are very good at high current, but at low current they are not the best lithium battery around. I wonder if the high current ability is due to a missing PTC protection or maybe it just triggers at a higher temperature?
