AAA R3 batteries are most commonly used in everyday life. They are characterized by their small size and very universal and versatile use. We use them in connection with commonly used electrical devices. They are connected by their size, but AAA R3 batteries differ in technical parameters, which translates into both their intended use and the quality of work and operation of the whole device. R3 means that they are alkaline batteries, but AAA batteries come in other variants. In this case, however, we are dealing with a much longer service life, as well as increased durability, as much as 40 times greater than in standard batteries. For this reason, they quickly gained popularity and became the first and sometimes the only right choice for many. Find out what Botland offers! In our offer you will find AAA alkaline batteries with different parameters. Choose the variant best suited to the specificity of your work and the type of your device.

AAA / R3 batteries
EverActive Pro AAA (R3 LR03) alkaline battery - 4pcs.
Alkaline battery AAA (R3) - The popular small stick, with a nominal voltage of 1.5 V . Price per 4 pieces .See also
AAA (R3) batteries – small but powerful
Each standard AAA battery (R3, R03) has a nominal voltage of 1.5V - however, this only applies to batteries as such, which should not be confused with rechargeable batteries of the same dimensions. The best R3 batteries available today have the prefix L, then their type is written as LR03 - the additional letter means that we are dealing with alkaline batteries.
Finger batteries of this type were produced using a different technology. Moreover, this type of battery has much better parameters (primarily higher capacity) than ordinary, slightly cheaper R03 batteries. With greater capacity, the operating time of the powered device increases.
Alkaline batteries - what else makes them stand out?
Alkaline batteries also perform better in applications with higher peak current consumption compared to regular batteries. Due to the previously mentioned small price differences, the use of regular batteries is unprofitable today - an alkaline AAA battery will work much better in virtually every application.
Uses of AAA batteries
Small " fingers " are convenient to use wherever there is limited space in the housing - that is why many portable devices, including computer mice, some electronic thermometers, small flashlights, etc. most often use this type of power sources.
While virtually all typical alkaline batteries are suitable for everyday use, for more serious professional applications it is worth choosing specialized batteries. When choosing a battery, first of all, you should match its size, dimensions and electrical parameters to the specific application.
All cells available in our store's assortment are of good quality and guarantee safe, stable and long-lasting power supply to devices. Their weight usually does not exceed 12 grams. In addition, AAA batteries are durable and resistant to external factors.
R3 battery - What's going on in the "fingers"?
In addition to the mentioned rated voltage, a very important battery parameter is their capacity. High-quality R3 batteries, supplied by well-known global manufacturers, can boast a capacity of up to 1200 or more mAh, which is a very good result for small AAA batteries, compared to much larger R6 batteries.
Technical specifications for industrial sticks may include typical internal resistance values and precise discharge characteristics. Are you looking for a battery that ensures long operation time of the powered device?
Check out our offer, where you will find products from renowned brands at competitive prices. We provide professional advice and fast and safe delivery of orders. Each product is described in detail, which eliminates errors when placing an order.
AAA batteries (R3) - FAQ
AAA battery (less often: triple AAA battery), commonly known as "little fingers", is a standard size of dry cell battery. AAA batteries are also classified as LR03 (IEC), 24A (ANSI/NEDA), R03, MN2400, AM4, UM4, HP16 and micro. The diameter of the AAA battery is 10.5mm and the length is 45mm. The AAA designation is commercial.
AA batteries have physical dimensions of 14.5mm x 50.5mm, while AAA batteries have physical dimensions of 10.5mm x 44.5mm. Due to the larger capacity of AA batteries, AA batteries usually have a larger capacity than AAA batteries.
The capacity of an AAA battery depends on the technology and the company that produced it. However, it is quite similar in almost every battery - it is approximately 1000 mAh. The capacity may therefore range from 900 mAh to 1100 mAh. Larger batteries offer greater capacity.
We will sell you a little lifehack. Hold the battery with the minus side facing down and drop it on a table or other flat surface. If the AAA battery is discharged, it will bounce higher and fall over, and if it is charged, it will stand upright. You can also use a meter .
