AA batteries are among the most common types of swappable power cells available today. Have you ever bought an AA battery and found out that it does not fit into your device while you have been using another type that fits well.
The AA batteries have different dimensions that can make them quite challenging. Nevertheless, the variation in sizes can be minimal that you even fail to notice. I recently bought an AA battery for my remote controller.
While buying it, it appeared to be the same size as my previous batteries. However, of course, the ones that I bought were from a different company. When I reached home, the batteries could not fit into the available space.
The size of the AA battery was 4.83 cm by 1.4 com, but the previous battery measured 5 cm by 1.41 cm. you can realize that the difference cannot be easily noticed.
Apart from the physical size, AA batteries vary in voltage size as well. The manufacturer always indicates these sizes; thus, you need not worry about that at all. They also differ with the capacities.
Device manufacturers make their devices have a standard space for the battery. They follow the standard size of batteries that the given regulatory bodies have in place. Thus, you cannot change the size of your device's space, but you can choose a different battery that fits into the given space.
This article is going to get different sizes of AA batteries. You need to know why there is a slight difference in the sizes of these batteries. Therefore, let us travel together through this tremendous helpful discussion.
This question is bothering most AA battery users. Therefore, we must go through this subject and help all users understand why the different sizes exist. There are guidelines given by IRE and ANSI on the required sizes of different batteries.
The standard size of an AA battery is 14.5 mm in diameter and 50.5 mm in length. Thus, device manufacturers use this size. This makes it hard t change the size of an AA battery because the device already has the standard dimensions.
The IRE and ANSI always give out the standard on the nominal values of the batteries' physical sizes. However, there is a small tolerance that manufacturers are allowed to adjust.
If we go with the nominal value of a battery, then there is one AA battery size. The tolerance allowed by each manufacturer brings about the difference. This is what gives us different sizes of AA batteries.
Nevertheless, the tolerance allowed is around a few thousands of an inch. Manufacturers, IRE, and ANSI understand that if tolerance is made too tight, then the production cost will be high, not a good thing for the consumer.
However, without considering the tolerance, there are different sizes of AA batteries. The different sizes of these batteries include the ? AA, 4/5 AA, and the AA. These are the standard AA batteries that we know, and we use them at home.
Thus, it is always good to have the right measurements of the device's internal space. This will help you get the right battery for your device and helps you avoid being stuck because you bought undersized or oversized batteries.
We need to compare the sizes of these two fantastic battery types. This comparison is mainly in terms of their sizes and capacity as well. 14500 lithium batteries are rechargeable cylinder-shaped batteries with a similar physical appearance as AA batteries.
The 14500 batteries have a typical voltage of between 3.6 – 3.7 volts. The capacity of this battery varies depending on the intended use and other features present. The capacity ranges from about 600 mAh to 2000 mAh.
As said earlier, the dimension of an AA battery is 14.5 mm by 50.5 mm. on the other hand, the dimension of a 14500 battery is 14.06 mm by 55.00 mm. you can notice that the AA battery is slightly bigger than the 14500 battery.
Thus, you should not assume that you could buy a 14500 battery for it because your torch uses an AA battery. You should first check the specifications of the torch before making your purchase.
When it comes to the sizes in terms of voltages, the AA battery is smaller than the 14500 battery. An alkaline AA battery has a voltage of 1.5 volts, while a rechargeable AA battery has a voltage of 1.2 volts. On the other hand, the voltage of a 14500 battery is 3.6 volts.
The ? AA battery is rare. It is mainly found in many unseen applications that include memory (CMOS) back-up, real-time clocks, utility meters, wireless alarms, and security contacts. Thus, they are many good batteries; you need to know if it can fit into your device.
? AA batteries offer the optimal solution for long-term battery use because they have a shelf life of 10 years. This battery has a voltage of about 3.7 volts when fresh.
This batter measures 14.55 mm in diameter and 25.00 mm by height. It has a capacity of about 300 mAh. The diameter can vary as much as 1 mm between different battery manufacturers. Likewise, the height of this battery can vary as well with the protruding end cap.
It is always good to have batteries from one manufacturer to avoid batteries that do not fit your device. Manufacturers agree that they cannot have their batteries having the same sizes as their partners because of the different production methods.
With the above comparisons, you can now have the best battery for your device. Get a battery that can last for an extended period so that you can minimize expenditure.
It is also advisable that you use batteries from the manufacturer that you have trusted, and you know the battery sizes they have. However, this doesn't mean that you should never use other battery types. If your current manufacturer's quality of batteries deteriorates, then it is good to move to another with similar product sizes.
