aaa电池是什么

aaa电池，是一种美国的干电池标准，中国大陆的7号电池或台湾的4号电池标准与其兼容。电池呈圆柱形，高43.6毫米

直径10.1室米。是一种常见的电池，比aa电池小。常用于体积较小，耗电量不太高的电子产品如MP3播放器、小型遥控器

等。既有一次性的碱性电池，也有可充电的镍氢、锂离子电池。

aaa电池是几号

aaa就是我们通常所说的7号电池。一般尺寸为:直径11mm，高度44mm。

aa电池是几号

aa就是通常所说的5号电池。一般尺寸为:直径14mm，高度49mm。

aa和aaa电池区别

1、大小不同

aa号电池的一般尺寸就是直径14室米，高度在49室米。而aaa号电池要比aa号电池小一点，尺寸是直径11室米，高度在

44毫米。我们从电池的外观来看就可以发现两者有很大的区别。

2、蓄电量不同

同种类型的电池，由于aa号电池要比aaa号电池大，所以aa号电池的电量要比aaa号电池多出一部分。

3、用途上不同

aa电池和aaa电池的用途都比较广泛，比如遥控器，电子玩具等其他产品上面。因为体积上的差异，aa电池的容量要比 aaa电池的大。所以不难发现大一些的电子产品通常会用到aa号电池，因为它所需要的电量更多，这样使用更持久。

what is aaa battery

The aaa battery is an American dry battery standard, which is compatible with the AAA battery standard in mainland China or the AAA battery standard in Taiwan. The battery is cylindrical with a height of 43.6 mm

10.1 meters in diameter. It is a common battery, smaller than aa battery. It is often used in electronic products with small size and low power consumption, such as MP3 players and small remote controls.

Wait. There are both disposable alkaline batteries and rechargeable nickel-metal hydride and lithium-ion batteries.

What is the size of aaa battery

aaa is what we usually call the 7th battery. The general size is: diameter 11mm, height 44mm.

What is the size of aa battery

aa is the so-called AA battery. The general size is: diameter 14mm, height 49mm.

The difference between aa and aaa batteries

1. Different sizes

The general size of the aa battery is 14 meters in diameter and 49 meters in height. The aaa battery is a little smaller than the aa battery, the size is 11 meters in diameter, and the height is

44mm. From the appearance of the battery, we can find that there is a big difference between the two.

2. Different power storage

For the same type of battery, since the aa battery is larger than the aaa battery, the aa battery has more power than the aaa battery.

3. Different uses

Both aa batteries and aaa batteries are widely used, such as remote controls, electronic toys and other products. Because of the difference in volume, the capacity of aa batteries is larger than that of aaa batteries. So it is not difficult to find that larger electronic products usually use AAA batteries, because it requires more power and lasts longer.
