Battery works, just stop CHARGING THEM!
Reviewed in the United States on February 25, 2020
I actually went and bought a set so I could leave a legitimate review for a company I feel offers great products and I have been buying from them throughout the years.
Most of the negative reviews listed where the poster (Just search through the reviews for the word "charge". I wanted to list all of their names however I fear it would flag my review as abuse) actually commented that the batteries leaked AFTER charging. Well SURE it did and you know why kids, cause Anker warns you that these batteries are NOT RECHARGEABLE and doing so can cause.. wait for it.. LEAKS!!!!
One reviewer is a photographer, and it just scares me to think what she delivers to her clients for her finishes products.
As for the concerns regarding their longevity.. only time will tell for me. I have 5 smoke detectors that where placed in my home the same day 2 years ago and it looks like they are starting to suffer from low batteries (3 out of 5 needed new ones), so took 3 and gave 1 a fresh set of these batteries and the other a fresh set of Amazon Basics and 1 set Energizer Lithiums, we will see who lasts longer and evaluate the cost value.
I've added photos of the box and batteries to show you that there are plenty of warnings NOT to charge these batteries, not to mention that the listing itself says "Non-Rechargeable"
One thing I will say, Anker has made a name for themselves in the business of USB Power Banks and other charging technologies, and even the logo on the batteries has a lighting bolt that usually indicates charging (for consumer products or "DANAGER, High Voltage" for industrial products. Perhaps put the words NON-Rechargeable on the package or at least remove the back section where you are promoting your charging technology. I get it, however it looks like people are just not getting it and what makes this a concern, people may get hurt including kids if their parents charge these batteries and place them in their kids toys..
