Test/Review of Etinesan Lithium AA

Etinesan Lithium AA


Official specifications:

  • 15-year shelf life




This is a Chinese brand of lithium cells











Lithium cell has a much more load tolerant discharge than alkaline, there is only a small variation in capacity and the voltage stays fairly high.
The 3A discharge looks funny, the cell starts cold and cannot deliverer the current, but when it heats up the performance gets better. I did also try a 5A discharge, but that was not possible.







With this low discharge current the cells are not better than a good alkaline, except the voltage is significantly higher.





Conclusion

For application with higher loads (like flashlights) Lithium batteries are very good, but they are usual considerable more expensive than alkaline. Lithium is also good at very low temperatures.
This cell looks good, but cannot match Energizer.



Notes and links

How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

On a scale of 1 to 10, where 10 is at par with Energizer Lithium and 1 is total junk, how would you rate these batteries?

After this test it looks like 8.

Cool. I won these batteries in an auction on eBay.

10 CR123A for $14.50
12 AA for $9.50

You think it’s a good buy?

thanks for yet another test!

If they were like 50cents each, I would be interested to have a few spare ones.

Lol I agree, if they were a little cheaper they would be worth it.
I’m on the lookout for inexpensive lithium AAA/AA.
Checked eBay and they are $24.41 for 16 of these Etinesan. The last batch of Energizer lithium AA I purchased 20 for $24.99 from a fellow on cpf.
They’re decent so hopefully the price of these will eventually drop.

Thanks for reviewing these HKJ!
