Tesla Batteries Black+ AAA Maximum Power Alkaline Batteries, 10- Year Shelf Life, A Long-Lasting Battery Life, Leak-Free, 4 Count [Pack of 1]

good

After doing a little research, I'm 99% certain that "Tesla Batteries" has exactly zero affiliation with the Tesla brand we have come to know in the US (electric cars, Elon Musk, etc). Any company associated with electricity would have reason to borrow the name of Nikola Tesla (because we all know executives aren't typically creative). They are not claiming to be be part of the US company, and they deal solely in batteries and power banks. Not to imply that a lack of affiliation (or uncreative name choice) is a good thing or bad thing, I only want to point out that whatever feelings you have towards Tesla automobiles and Mr. Musk, they are completely irrelevant here.That said, the batteries seem great so far, no problems with them. There seems to be little info though, on this page or on the teslabatteries.com website about just what makes these Black+ "future batteries" any different from their Silver/Gold/blue varieties or from any other brand. The Black+ line is not even mentioned on their website that I could find. These are labeled as alkaline batteries and the package shows icons of a keyboard, a toy car, and a radio, so clearly these are intended for electronics. The same 3 icons are shown on the Silver+ batteries on the website and the labeling is similar, right down to the "Future Batteries" and "Plus Extra Energy" so maybe the Black+ is just a branding experiment? Whatever the case, the current $6.29 price tag is no gift, but for a small package it would seem comparable to other name brands, and I've found no fault with the batteries themselves so far.

I have enjoyed these batteries the past few months. I used them with my daughter's walker that plays sounds and lights, and have just now had to change them out after about 3 months of some good usage by my kids. They lasted longer than I expected. If used in a remote for say a TV, I would expect them to last over a year. The cost does a good job of reflecting the preformance of this product. I can see how they are a competitor with top brands like duracell. Definitely worth considering.

I wasn't aware that Tesla made batteries, but decided to give these a try. The future of batteries, it says. The way that they are advertised, being long lasting, I got them for my remote controls. I have no idea why I still have to many remotes, but hopefully, I don't have to deal with changing out the batteries for another year or two. So far, they are working well.

Excellent for all aaa battery uses. They work and so far they have good longevity.

Not much to say here: we put them in a remote, they work, are standard batteries. Haven't had them long enough to test longevity, but no reason to suspect any issues.

I don’t know if Tesla’s battery is real or fake, so I bought it and tried it. The price of the battery is indeed a bit high. Maybe it uses some black technology? The batteries I used on this smart door lock before are all new, but the displayed capacity is only 75%, but this time I use Tesla’s, and it shows 100% charged. I think it’s a bit miraculous.It's designed to look really nice.

These are standard AA batteries. I put them in a clock and in a remote control. They work. I can’t see the reason for the price point. You can purchase other name brand batteries that work just as efficiently and last as long for less money.
