Designation: It is primarily the terminology that differs. Battery size and shape are typically defined by "CR123," while battery chemistry and characteristics are considered by "CR123A." Chemistry: Using lithium chemistry, these batteries produce a stable voltage of 3 volts and provide high energy density.
3600mAhThe 18650 maximum capacity of Samsung, Panasonic, LG, Sony, and Toshiba can reach more than 3600mAh. But as of 2021, there is no 18650 battery with a rated capacity of more than 3600mAh or 30A CDR. Suppose you see any 18650 batteries on the market that are above these specs.

How long do unused 18650 batteries last? Unused 18650 batteries can retain their charge for several months or longer, depending on their quality and self-discharge rate. Generally, they might hold a charge for six months to a year, but this can vary.
If we multiply 15,000 by his estimated driving range of 217 miles, we get 3.25 million miles in the worst-case scenario, which is when the battery fully discharged and charged every cycle. Therefore, Tesla's progress in obtaining a battery that lasts a million miles is obvious.
Despite China holding less than 7 percent of the world's lithium reserves, China has managed to secure an 80 percent share of global lithium chemical production, 78 percent of cathode production, and a staggering 70 percent of cell manufacturing for the electric car industry.

In summary, the cost of 18650 batteries is largely due to the advanced technology, rigorous safety standards, high capacity, and the specialized manufacturing processes involved.

NO. AA batteries run at 1.5 volts average for around 1800 Milliamp hours while 18650s run at around 3.7 volts, and around 3000 milliamp hours. you could use AA rechargeables, but you would need many more of them for the same purpose, and they wear out much faster.
