Test/review of Eoaneoe LS16340 2500mAh (Purple)

Eoaneoe LS16340 2500mAh (Purple)

Official specifications:

  • Color: purple

  • Size: 65x35x15mm

Record breaking capacity in 16340 or a scam?

There is a large difference between the battery, one has about 220mAh the other 280mAh and they are very hard pressed to deliver 1A


16340 batteries with this high capacity rating do not exist, this battery is also very bad at delivering current.
Rating is of course bad

Thanks for the review, I like that you not only review the top contenders, but especially the items that are not necessarily good. A neutral or negative rating is as important as the good ones.


Had my hopes up there :smiley: :person_facepalming:

I believe that it is important to review both good and bad, how else do you show that not all batteries are created equal.
A 2500mAh 16340 is, of course, rather obvious as a bad cell, but that is only valid for people that knows about batteries and I hope my audience is slightly bigger than that, even though I am rather technical.

Thanks for the review. Crazy stuff out there, waiting to be snatched by an unsuspecting buyer. I have even seen 16340 2800 mAh cells on Aliexpress.
