I've learned a lot about batteries over the past 6 months. I had always used alkaline and even though they are the least expensive, when they run out you have to keep buying them over and over again. So I started buying Nimh rechargeables and soon learned about their shortcomings. The biggest problem is that Nimh only output 1.2 volts instead of the expected 1.5 volts produced by alkaline and lithium. The second problem is that both alkaline and Nimh do very poorly in cold weather. I was constantly having to maintain outdoor devices like tempeture sensors, battery operated lights and other devices in the cold garage with replacements.Then I happily found lithium! These output a full 1.5 volts and they are not degraded by cold temps. The lithium power curve is also important because the 1.5 volts stays constant until the battery is exhausted. With alkaline and Nimh the power just continuously weakens until the battery becomes too weak to work.One last thing is charging. You can't use an Nimh charger for lithium, they have different charging protocols. What I like about this brand is that it charges with a USB C cable so I'm not worried about making the mistake of fatally charging my lithiums in an Nimh charger. Five stars for sure!

These are great! The convenience of not having to constantly rebuild batteries is outstanding! Easy to use. Charges quickly.

I have wrist blood pressure cuff that uses AAA batteries. It discharges Alkaline batteries after 30 or so measurements, so I tried NiMh rechargeables. The cuff said the NiMh rechargables were run down even when they were freshly charges, but these Lithium rechargeables output a higher voltage and will work in the cuff so I can stop buying (and spending $) lots of Alkaline batteries for my BP cuff. These work longer than the Alkaline batteries I was using. You don't need a special charger for these batteries which is a nice bonus.

If you're like me and you need batteries for whatever reason these are great to have. I don't have to go to the store constantly to buy new batteries. I can charge four at a time and always have batteries in hand to use in case I need them. I even bought some adapters that clip onto these AAA batteries and make them into Double A batteries. So go look for those and you'll save even more space rather than having so much clutter

Handy to have for a quick fix if you need some spare power. I haven't had any problems with these. Everything about them is great except one thing and that is they do not last long at all. At least in high power devices. I've been using them in my small UV flashlight, which takes 2 AAA. After a full charge 2 of these AAA's will last approx. 3-5 minutes before they die on me.
