A 18350, rated for high capacity by manufacturer, but rated lower by shop. It is also rated for very high current drai.

The discharge curves are nice with good tracking and fairly constant capacity at around 700mAh, the cell can deliver 7A, not the rated 30A.

Conclusion

For a 700mAh high current cell it is good, but the specifications on the cell has nothing with reality to do.

Disappointing since the Aspire cells are discontinued. I was hoping to see something nice to replace those.

That’s the reason I came here too. Otherwise I wouldn’t spend time looking at a *fire review.
