小号电池
时间:2023-02-23 10:08:11        点击量:【 】次

在日常生活中,用得最多的就是7号、5号、纽扣式之类的小号电池,像遥控器、电动玩具、计算器、电子表等电子产品都离不开它们,多为一次性电池,电池容量相对较低。

7号电池:即AAA电池,常用于体积较小、耗电量不太高的电子产品,比如小型谣控器、电动小玩具之类5号电池:即AA电池,电容量和体积比7号电池稍大一点,用途差不多,一般适用于手电筒、电动玩具等:纽扣电池:外形类似一颗小纽扣,一般用于在各种微型电子产品中,比如电子表、计算器、电子词典等选购要点:市场上的小号电池多为干电池和碱性电池,千电池价格最便宜但电池容量低,小编建议选择更耐久的碱性电池,不仅电量是干电池的7倍,而且电流输出稳定,不漏液。


In daily life, the most commonly used are small batteries such as No. 7, No. 5 and button type. Electronic products such as remote control, electric toys, calculators, electronic watches and so on cannot be separated from them. Most of them are disposable batteries with relatively low battery capacity.


No. 7 battery: AAA battery, which is often used in electronic products with small size and low power consumption, such as small radio controller, electric small toys, etc. No. 5 battery: AA battery, which is slightly larger in capacity and volume than No. 7 battery, and has the same purpose, and is generally applicable to flashlights, electric toys, etc.: button battery: similar in shape to a small button, which is generally used in various micro electronic products, such as electronic watches, calculators Key points for purchasing electronic dictionaries and other items: Most of the small batteries on the market are dry batteries and alkaline batteries. The price of 1000 batteries is the cheapest but the battery capacity is low. The editor of maigo suggested to choose a more durable alkaline battery, which not only has 7 times the power of dry batteries, but also has stable current output and no leakage.
