Button batteries are widely used in a variety of industries in our lives, the common types of batteries are No. 2 batteries (D-type batteries), No. 2 batteries (C-type batteries), No. 5 batteries (AA batteries), 7-day batteries (AAA batteries), 9V batteries (PCP batteries, PPP3 batteries), and finally smaller coin cell batteries, leading everyone to understand the button batteries.
1. Classification of button batteries
At present, the common button battery on the market is divided into two categories, primary recharge battery and secondary recharge battery, the key of primary recharge battery is 1.4V zinc-empty battery, 1.9V LR alkaline battery, 3V SR silver oxide battery, 3V CR lithium battery battery, etc.; The key to secondary recharge batteries are 3.7V LIR batteries, Ni-MH nickel-metal hydride batteries, Ni-Cd nickel-cadmium batteries, etc.
2. Acquisition of button batteries
When purchasing button batteries, be sure to see the mercury composition of the battery casing, to understand that a mercury-containing battery can pollute more than 40,000 glasses of water, like "zinc electric grade" button batteries, due to the production and processing technology, will contain mercury, such as alkaline batteries, silver oxide batteries, zinc-air batteries, etc.
3. Selection of button batteries
Speaking of the environmental pollution damage of mercury-containing batteries, then in the case of the application of button batteries, in the case of selecting batteries suitable for the natural environment according to the detailed situation, try to prevent the selection of mercury-containing button batteries to prevent excess air pollution. Primary batteries and secondary batteries rechargeable batteries should be distinguished, effective standard applications.
The above is the key point sharing about the classification of button batteries and their acquisition, for this matter, do you have a clearer understanding of button batteries? Protecting the ecological environment starts with me, let's effectively apply the standard button battery.
