![]() ![]() It delivers a capacity of 350-1200 Milliamps per hour. The AAA packs smaller electrochemical material, and therefore the capacity is limited. The two batteries have different capacities mainly because of their size difference. It is measured in ampere-hours or Milliamps per hour (mAh). The capacity of a battery refers to the amount of charge generated by the electrochemical reactions in the battery. AA batteries are 14.5 mm in diameter while AAA are 10.5 mm in diameter. They measure 44.5 mm (height) x 10.5 mm (diameter). AAA has a smaller diameter and length to fit in the smallest toys. Their standard size is 50.5 mm (height) x 14.5 mm (diameter). The AA is taller, wider, and generally larger than their AAA counterparts. They both have the same cylindrical shape but different dimensions. Size is the most noticeable difference between the two batteries. Here are the key differences between AA and AAA. Although both batteries perform similar functions, certain things set them apart. If you are looking for alkaline batteries, it’s easy to confuse AA with AAA batteries. Unlike AA batteries, they have a lower power capacity and are more effective for devices like remote controllers, smaller toys, and kitchen timers. They have also existed for over 100 years but came in four years after AA. They rank second in the popularity of dry cells after AA. ![]() On the other hand, AAA batteries, also known as Triple A, are smaller than AA, and the name doesn’t represent anything besides the type of battery sizes they are. These batteries are bigger than AAA and are mainly used for devices such as TV remotes, wall clocks, handheld kitchen gadgets, and flashlights. ![]() Instead, it’s a name for a standard battery size with nominal voltage. It is important to note that the name AA does not have a particular meaning. Although technology has significantly evolved and many devices use rechargeable batteries, dry cell batteries remain significant in powering most handheld devices. AA batteries have existed for over 100 years and have continued to be effective in modern-day devices. They contain a moist medium or paste charged with electrolytes, allowing electric current to pass through. AAA Batteries: OverviewĪA batteries use dry cell technology to power small electronic devices that do not require a lot of power. TV remote controls, wireless computer mice, small toys, handheld games, portable radios ![]() Remote controls, digital cameras, flashlights, toys, portable speakers In this article, we will compare the two batteries side by side, examine their key differences and discover how they are used in different devices. The amount of electrochemical materials in both batteries also varies, meaning they also deliver different power capacities. However, the two batteries differ in various aspects, such as size, use cases, and price. The two types of batteries provide a wide range of uses in our daily devices, like toys, TV remotes, wall clocks, and digital cameras. is a bit of a problem in my country and even in US they cost a hell lot.Īnd i m not in favour of spending money on hobby.There are many types of alkaline batteries, but the most popular ones are AA and AAA. Getting parts specially made for robotics like gears etc. i just pointed at the object in the shop like a kid saying "i want that". (dont know what it means but the guy i bought them from told me that. i m in the process of testing the reliability of the FM RX and TX modules and would replace the wire between the robot and the compu soon.ģ)i used simple rubber bands as belts to connect the motor to the wheels. sorry for the delay.Ģ)for the time being i m using software to generate dtmf tones thru the soundcard whereby i connect the robot. so i was waiting for the bot to complete and then i would finish a roll of conventional film on it and then get them scaned. but too bad i dont haveĪ webcam/scanner at home. 1) I would love to post my bots pics in the forum. ![]()
