More than any other battery, I'm a big fan of Duracell copper-alkaline batteries. Except when it comes to price. And that's the main reason why I mostly switched to batteries. I started with several projects, each requiring 2-4 AAAs and/or AAs. On average, about 20 batteries of each type are used at the same time. I just can't afford to change all those batteries that often. While these Revain Basic AAAs don't last as long in the gear, they're a lot more economical. They therefore have to be changed more often in my devices than good bases. It's about every 3 weeks instead of the 5 weeks I get with alkaline. But after using the alkali I had to throw it away. I've tried several different chargers designed for alkaline chargers, but almost always some Duracell alkaline chargers have leaked and actually exploded. I often have to charge batteries unattended when I'm not at home. The last thing I want is to burn the house down. So I started using these AB brand batteries as well as EBL brand batteries a few months ago. It took some time to get used to the shorter replacement cycles. I usually have a habit of completely draining alkaline batteries and swapping out the batteries of each device as needed. Now every 3 weeks or so I just take out all the batteries in groups of 8 and recharge them in a day or two. Then you don't have to worry about whether the batteries are almost empty or not. There are other disadvantages to using such rechargeable batteries instead of alkaline batteries. Not only do they not last as long on a single charge, but they also have a higher failure rate. Some will die and just stop charging after only 10 charges. But others, even of the same brand and batch, will charge 50 or more times in their lifetime. You just don't know how long her life is. But even those that do not have a long service life make it much easier on the wallet to buy batteries. Some of them end their lives one day by just not charging, while others gradually get worse and worse at holding a charge. It will be much easier for you to buy twice the amount of batteries you need. This allows you to charge your device while good batteries are still installed in the device. And as mentioned, sometimes you have to buy more as some of the originals are reaching the end of their life cycle. But then again, it's still a lot cheaper than throwing away and buying alkaline batteries all the time. Since this rating is AAA, I have to say that most people will use it for small devices like remote controls or calculators. AAAs don't have the power or durability to power large or motorized devices. Although they're listed for 1.5 VDC, they only supply 1.2 VDC when their charge decreases. If you've ever seen a device with instructions warning you not to use rechargeable batteries, this is usually why. A remote control that needs to have 3VDC from two batteries may not like a pair of rechargeable 2.4VDC batteries. It depends on the device you are using. Summary: As long as you have a good, reliable charger (I recommend the ones that plug into the wall, not USB) and aren't trying to power motors or large appliances, these AAA batteries will work great. Just consider the disadvantages of batteries mentioned above.
