18650 batteries have a nominal voltage of 3.6V, so this means you would need 3 AA batteries in series configuration (attached end to end) to get the same voltage as just one 18650.

lithium ion AA and AAA batteries - this is really confusing because technically there is no such thing as rechargeable Li-ion 1.2 or 1.5 volt button top consumer batteries. However, there are AA size rechargeable Li-ion batteries. ... They are approximately the size and shape of two AA batteries but they are connected.

Actually, AA and AAA are also 1.5 volts. That makes you wonder what the difference is. If they're the same voltage, why not just use all AAA batteries and make things lighter and smaller. But there is a big difference between them all.

AA and AAA are battery designations that used to show the size and the potential charge capacity of the batteries. AAA batteries are smaller to that of AA. The important thing in comparing their sizes is that you can place an AAA Battery into the slot made for the AA battery.

Although the batteries are the same chemically, the size and the form factor are very different. The Einhell drill will last much longer then the B&D or do tougher jobs; that's to do with the capacity. Neither will fit in the other due to the different form factors.

You're right, C and D batteries both are 1.5 volts. Actually, AA and AAA are also 1.5 volts. That makes you wonder what the difference is.

AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size there is a big difference between them all. ... That's where battery size comes in. The D size battery will deliver more current than the C, AA, and AAA size battery.

No, unfortunately there are very small differences in size of 9 volt batteries, even in brand name 9v batteries such as Energizer (or Energizer Industrial) and Duracell (or Duracell Procell). ... The dimensions for 9 volt batteries are H 48 mm × L 25 mm × W 15 mm (1.9 in × 1 in × 0.6 in).

A C battery measures 50 millimetres (1.97 in) length and 26.2 millimetres (1.03 in) diameter. The voltage and capacity of a C-size battery depends on the battery chemistry and discharge conditions. The nominal voltage is 1.5V.

Batteries are classified according to standards. LR03 is the corresponding IEC classification, as AAA is the same battery but according to ANSI classification.

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.

Size matters A bare “unprotected” and “flat top” 18650 battery will always be 18mm in diameter (width) and are 65mm long (give or take a little manufacturing tolerance). AA batteries on the other-hand are 13.5-14.5mm in diameter, and 49-51mm long.

An AA cell measures 49.2–50.5 mm (1.94–1.99 in) in length, including the button terminal—and 13.5–14.5 mm (0.53–0.57 in) in diameter.
