Batteries are widely used in various industries in daily life. Common battery types include AA batteries (D-type batteries), AA batteries (C-type batteries), AA batteries (AA-type batteries), and AA batteries. (AAA type battery), 9V battery (semiconductor battery, PPP3 battery), and then the smaller lithium button battery. Below, Dongzan Lithium Energy will take everyone to learn about button batteries.

1. Classification of button batteries

The common button batteries currently on the market are mainly divided into two categories, primary rechargeable batteries and secondary rechargeable batteries. Primary rechargeable batteries mainly include 1.4V zinc-air batteries, 1.9V LR alkaline batteries, and 3V SR silver oxide batteries. , 3V CR lithium batteries, etc.; secondary rechargeable batteries mainly include 3.7V LIR batteries, Ni-MH nickel metal hydride batteries, Ni-Cd nickel cadmium batteries, etc.

2. Acquisition of button batteries

When purchasing lithium button batteries, be sure to read the mercury component label on the battery casing. You must understand that a mercury-containing battery can pollute more than 40,000 cups of water. Like "zinc-grade" button batteries, due to manufacturing Due to the craftsmanship, it is very likely to contain mercury, such as alkaline batteries, silver oxide batteries, zinc-air batteries, etc.

3. Selection of button batteries

Speaking of the pollution hazards of mercury batteries, when using button batteries, choose the battery type that is suitable for the environment according to the actual situation, and try to avoid selecting button batteries containing mercury to avoid causing unnecessary air pollution. Primary batteries and 2 Secondary batteries and rechargeable batteries must be distinguished and used in a reasonable and standardized manner.

The above is the sharing of key points about the classification and purchase of button lithium batteries. Regarding this matter, do you have a clearer understanding of button batteries? Protecting the environment starts with me, let us Let’s use button batteries in a reasonable and standard way.
