## 摘要 / Abstract

AA（5号）和AAA（7号）是最常用的两种电池规格。本文从容量范围、尺寸重量、适用设备、应用场景等维度进行全面对比，帮助您选择最合适的型号。

AA and AAA are the two most commonly used battery specifications. This article provides a comprehensive comparison from dimensions such as capacity, size, weight, applicable devices, and application scenarios.

## 正文 / Full Text

### 尺寸与重量对比 / Size and Weight Comparison

AA（5号）电池：直径14.3mm，长度50.5mm，重量约20g。AAA（7号）电池：直径10.2mm，长度44.5mm，重量约8g。AA电池体积约为AAA的2.5倍。

AA (size 5) battery: 14.3mm diameter, 50.5mm length, about 20g weight. AAA (size 7) battery: 10.2mm diameter, 44.5mm length, about 8g weight. AA battery volume is about 2.5 times AAA.

### 容量对比 / Capacity Comparison

AA 1.5V锂电池容量覆盖2400mWh到4070mWh五个档位，最高容量是AAA的3.7倍。AAA 1.5V锂电池容量覆盖600mWh和1100mWh两个档位。

AA 1.5V lithium battery capacity covers five tiers from 2400mWh to 4070mWh, maximum capacity is 3.7 times AAA. AAA 1.5V lithium battery capacity covers 600mWh and 1100mWh two tiers.

### 应用场景对比 / Application Scenario Comparison

AA电池适合功耗较高的设备：智能门锁、电动玩具、强光手电、医疗设备（血糖仪/血压计）、电动牙刷等。这些设备需要大容量和较高工作电流。

AA batteries suit higher-power devices: smart locks, electric toys, high-power flashlights, medical devices (glucose meters/blood pressure monitors), electric toothbrushes. These devices need large capacity and higher operating current.

AAA电池适合功耗较低、空间受限的设备：遥控器、无线鼠标、耳温枪、挂钟、激光笔、蓝牙耳机充电仓等。这些设备对电池体积和重量敏感。

AAA batteries suit lower-power, space-constrained devices: remote controls, wireless mouse, ear thermometers, wall clocks, laser pointers, Bluetooth earphone charging cases. These devices are sensitive to battery size and weight.
