1 Size. Many things make these two batteries different, but the most obvious is their size. Although both batteries are cylindrical, their sizes are still different. Forexample, the Energizer 9 volt battery is approximately 1/16” taller than the Duracell Procell 9 Volt battery. There are indeed ‘battery standards’ for battery manufacturers to follow. The dimensions for 9 volt batteries are H 48 mm × L 25 mm × W 15 mm (1.9 in × 1 in × 0.6 in). However these standards still allow for varying in Moreinfo on the 21700: Everything You Need to Know About the 21700 Battery. Various Battery Sizes. The following is a picture showing various battery sizes. The 18650 is 1170 cubic mm, the 14500 and AA are 700 cubic mm, the AAA is 467 cubic mm. Note the 14500's cannot be used in all AA devices unless they support both 3.7 and Thisis because the manganese dioxide in LR03s are purer, denser, and takes less space in the internal compartment as the electrodes do. In fact, the AAA LR03 batteries can provide between three to five times the capacity of the R03 battery. An LR03 AAA cell capacity ranges between 860 - 1200 mAh while that of R03 is only 540mAh. TheAA and AAA battery size may look very similar, but they are different in size. The AA batteries are more petite than AAA batteries, with an average length of 50mm and a ACR-V3 battery (sometimes CRV3) is a type of disposable high-capacity 3-Volt battery used in various electronic appliances, including some digital cameras. It has the shape and size of two side-by-side AA batteries. [1] This allows CR-V3 batteries to function in many (though not all) devices originally designed for only AA batteries. Ctype batteries are built to a standard size to ensure maximum compatibility with both devices and accessories such as battery holders. C-sized batteries are smaller than D batteries but larger than AA and AAA batteries. They are: 50mm or 1.97 inches in length. 26.2mm or 1.03 inches in diameter.
