Do batteries have a shelf life? How to dispose of batteries?

Batteries have positive and negative electrodes. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. In 1890, Edison invented the rechargeable iron-nickel battery. Common batteries include: dry batteries, storage batteries, and lithium batteries. Dry batteries are also called manganese-zinc batteries, and their voltage is 1.5 volts. Storage batteries are one of the most widely used batteries. It is a common item in our lives. Do many friends and curious batteries have a shelf life? Let's find out below.

Do batteries have a shelf life?

Batteries have a shelf life. The shelf life of alkaline batteries is more than three years, while the shelf life of ordinary batteries is only one year. In addition, batteries are classified into four types according to electrolytes, namely alkaline, acidic, neutral, and organic electrolytes. When purchasing batteries, you should choose those with the national inspection exemption mark, neat appearance, and recently produced varieties.

1. Has a shelf life

Batteries have a shelf life, and different types of batteries have different shelf lives. Alkaline batteries can generally be stored for three years, while ordinary batteries can only be stored for one year. In the process of storing batteries, they should be placed in a dry, ventilated, and light-free area to prevent corrosion of the battery case.

2. Purchase method

When purchasing batteries, you should observe the packaging and instructions. It is best to choose products with the national inspection exemption mark or well-known brands. During the purchase process, you should also check the battery's production date, shelf life and packaging. It is more appropriate to choose batteries with a recent production date and exquisite packaging.

3. Product classification

Batteries are divided into four types according to the electrolyte: alkaline batteries, acid batteries, neutral batteries, and organic electrolyte batteries. The electrolyte in alkaline batteries is mainly KOH, the electrolyte in acid batteries is aqueous sulfuric acid solution, and the electrolyte in neutral batteries is salt solution.

How to dispose of batteries

The environmental protection department said that household batteries have met the national low-mercury or mercury-free technical requirements and can be disposed of separately with daily household waste without centralized recycling. If there is an old battery repurchase organization near your residence, you can also send it there. Note: Button batteries, electric vehicle batteries and other lead-acid batteries and nickel-cadmium batteries still need to be recycled.

A battery is a device that contains an electrolyte solution and metal electrodes to generate an electric current in a cup, tank or other container or part of a composite container that can convert chemical energy into electrical energy.

Batteries have positive and negative electrodes. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. In 1890, Edison invented the rechargeable iron-nickel battery.

Common batteries include: dry cell, storage battery, lithium battery. Dry cell is also called manganese zinc battery, with a voltage of 1.5 volts. Storage battery is one of the most widely used batteries.

What kind of garbage do dry batteries belong to?

Dry batteries are hazardous waste. In daily life, the dry batteries people usually use are zinc-manganese batteries, which contain highly toxic mercury. In addition, zinc is also a harmful substance that can cause environmental pollution to the air, water sources, soil, and other places, and harm the growth of organisms and crops.

Dry cell batteries are disposable batteries and belong to the primary battery class of chemical power sources. They are suitable for flashlights, radios, cameras, toys, etc. They are also widely used in various fields of national construction such as national defense, telecommunications, aviation and navigation.

Hazardous waste mainly refers to discarded batteries, waste light bulbs, waste medicines and other household waste that are harmful to human health and pollute the natural environment. When placing hazardous waste, please pay attention to sealing the package and placing it in the hazardous waste bin.
