Batteries are common energy storage devices in our daily life. Different types of batteries have different standard voltages. This article will introduce the standard voltage of various batteries, including common dry batteries, lithium batteries, Ni-MH batteries, etc., to help readers better understand the characteristics and applications of batteries.

Dry Battery

1. AA dry battery: the standard voltage is 1.5V, which is usually used for electronic equipment, remote control, etc.
2. AAA dry battery: the standard voltage is 1.5V and the volume is small, which is common in small electronic equipment and toys.
3. 9V dry battery: the standard voltage is 9V, which is used for some special equipment such as smoke alarm and digital camera.

Lithium battery

1. lithium Ion Battery: the standard voltage is 3.7V, which is widely used in mobile phones, laptops, cameras and other portable devices.
2. Lithium polymer battery: the standard voltage is 3.7V, which has higher energy density and safety, and is commonly used in smart watches, Bluetooth earphones and other devices.

NI-MH battery

2. AAA Ni-MH battery: the standard voltage is 1.2V, which is suitable for small electronic devices, remote control, etc.

Lead-acid battery

1. battery: the standard voltage is 2V, which is widely used in UPS power supply, solar energy systems and other equipment requiring large capacity energy storage.

Zinc-manganese battery

1. battery: the standard voltage is 1.5V, which is commonly used in flashlight, remote control and other daily necessities.

Zinc air cell
