26650 vs. AA Battery
Comparing 2 standards across 4 specifications. 4 key differences identified.
Comparing:
26650
AA Battery
A 26650 Li-ion cell measures 26mm in diameter and 65mm in length, used in high-drain devices like flashlights, power tools, and RC-hobby battery packs. The format is produced in multiple chemistries with different nominal voltages, so '26650' alone does not guarantee a specific voltage.
A standard AA battery measures 14.5mm in diameter and 50.5mm in length. Primary Alkaline cells output 1.5V, NiMH rechargeable cells output 1.2V. Inserting a 3.6V 14500 Li-ion cell into 1.5V AA devices destroys the circuit.
