The labels 18650 and AA technically just refer to different battery sizes. The key distinction is that the 18650 is specifically a size for a rechargeable lithium-ion battery while AA can be zinc-carbon, alkaline, nickel-cadmium, nickel-metal hydride (NiMH), or even lithium-ion among others.
Can I use AA batteries instead of 18650?
Can I use AA batteries instead of 18650? – Quora. 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.
Can a AA battery charger charge 18650?
