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

These Tesla Black+ AAA Maximum Power alkaline batteries are pretty average in performance. They work fine for basic household devices like remotes, clocks, and small gadgets, and I didn’t run into any issues with installation or compatibility.The advertised 10-year shelf life is nice, but in real-world use they feel similar to other standard alkaline batteries in this price range. They don’t seem to last noticeably longer than brands I’ve used before, especially in higher-drain devices.For low-power electronics, they get the job done without any problems, but I wouldn’t expect premium or extended performance. They’re also not the best choice for anything that needs strong or long-lasting power output.Overall, these are okay batteries for everyday use and backup storage, but nothing particularly impressive compared to other mainstream options.

These seem good! I will be back to review to see how long they last in my nail filer!

Last longer than dur*cell and n-ergizer

Works 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 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.

I am not sure what the “advantage” of these alkaline batteries would be over other brands, but I can say that — so far — they are working as expected. Hopefully they will last a little bit longer than others, but that is yet to be determined. I wish the packaging and the product page had more information about these batteries so I knew what (if anything) makes these different than their competitors.

Horrified I was charged £13.99 for the delivery charge of such a small item. Terrible experience.

Good

Does not last long even with medium load devices

Made in China not a product of czech republicUpdate: after use, complete trash, went dead after one run in a device
