NiMH with a high capacity and very low weight, this is too good to be true.













About 1/20 of rated capacity.













Conclusion

These batteries are a waste of money, maybe something can be recycled from them, but most likely they belong in a landfill.
Rating is bad.



Notes and links

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

A acquaintance of mine, who has the 3000mAh “improved” version of these ones, answered me “because they're made from light alloy” upon asking him what he thought about the reason behind their much lighter weight versus his old set of branded ones…

Cheers ^:)

Another pair for the hall of shame.

Thanks for testing HKJ

Hahaha this must be a record low capacity.

Thanks for the review mate.

So glad that people like you and NLee do extensive testing so that consumers know who the worst offenders are.
