Yeah the ideal replacement would be a 14500 or 18650 but they run at 3.7v so they would break a lot of electronics meant for alkalines. There are also CR123A batteries which are lithium primary cells and are much better for low temp applications or for long storage times. They also have a matching 16340 rechargable type which has a similar voltage.
The problem is, the average consumer is too dumb to be able to understand the difference, even the enthusiast flashlight/dive light/firearm light people have some holdouts who insist everything should just be alkalyne because they don't understand any of this.
- mrguyorama 3y agoThey make AA size batteries that have a lithium battery inside along with built in voltage dropping, protection, and charge circuitry. They are cheap.
- edrxty 3y agoThose are rough because the buck regulator is ~80-90% efficient and takes up space that would otherwise be battery. Any advantage they have over the NiMH cells is marginal at best, but they at least theoretically have a better discharge curve for stuff that's very voltage sensitive.
