Test/Review of Energizer Ultimate Lithium AA
Energizer Ultimate Lithium AA
Official specifications (The second part of the specification is from datasheet):
This battery handles load very well. Notice that the unloaded voltage for lithium batteries is 1.8 volt. I am not that impressed with the 11x longer specification, you must compare to some really bad batteries for this to be true. Up to 1A the capacity is nearly constant and even at 3A it can deliver energy. The 3A curve starts with a dip, then it raises again, when the battery gets warm. Due to the higher voltage, it has more energy than alkaline. Conclusion This battery is very impressive at high current, but at low loads it is not much better than alkaline batteries (Except it does not leak). The batteries have a very long storage time. These batteries cannot always replace alkaline, some equipment depends on the weak high current ability of alkaline! Notes and links How is the test done and how to read the charts Comparison of AA battery chemistries
