![]() ![]() The charge storage capacity of AAA Batteries (up to 1200 mAh) is less than the capacity of AA Batteries (up to 3000 mAh).AAA Batteries are smaller than AA Batteries.The type of batteries also affects the price, Rechargeable batteries are more expensive than Disposal batteries. But If you compare AA zinc carbon vs AA alkaline (or AAA zinc-carbon vs AAA alkaline) then Alkaline batteries are more expensive. ![]() AAA Batteries are slightly cheaper than AA batteries. As the Cost depends on the material used, types, and brand of batteries. CostĬost is another important aspect to compare AA and AAA Batteries. But AA and AAA Batteries are still popular in wireless mouse and keyboards, remote controls, wall clocks, smoke sensors, multimeters, and many other similar devices. Nowadays, Lithium-ion battery is replacing AA and AAA batteries in flashlights, camera, etc. Whereas, AAA Batteries are used in devices that require less energy such as Clocks and TV Remotes, etc. As AA batteries are heavy duty and have more charge storage capacity, they are used in devices that consume more energy such as Radio, Torch, Toys, etc. Applications and UsesĪA and AAA Batteries are also different in terms of which devices they are used with. A lithium battery usually stores more charge than an alkaline battery. The capacity of the battery depends on the material it is made up of. As a result, If we compare AA and AAA batteries with the same Power, then AA batteries will last almost twice the AAA batteries. However, if we use AAA batteries in device that requires more power then they will exhaust soon and hence we need to replace them more frequently. This means AA batteries are suitable for low- power devices. Whereas the capacity of AAA Batteries is 350 to 1200 mAh. AA battery typically has a capacity of 2000 to 3000 mAh. Charge Storage Capacity and RuntimeĪA batteries have a larger charge storage capacity than AAA batteries. ![]() Hence AA batteries are slightly longer and thicker than AAA batteries as shown in the figure. Whereas, Its diameter is (13.5-14.5) mm for AA and 10.5 mm for AAA Batteries. If you compare the length of AA and AAA Batteries, It is approximately (49.2-50.5) mm for AA Batteries and 44.5 mm for AAA batteries. AA batteries are slightly larger and wider than AAA Batteries. The most obvious difference between AA and AAA Batteries is their physical size and dimensions. ![]()
