Lead-Acid Automobile Batteries
Lead-Acid automobile batteries are types of rechargeable batteries usually used on our cars. Almost any retailer that sells lead-acid batteries collects used batteries for recycling, as required by most state laws. Almost 90% of the lead-acid batteries are recycled.


Non-Automotive Lead-Based Batteries
Gel cells and sealed lead-acid batteries are commonly used to power industrial equipment, emergency lighting, and alarm systems. The same recycling process applies as with automotive batteries. An automotive store or a local waste agency may accept the batteries for recycling.

Household batteries - Dry-Cell Batteries
This is the common battery we used everyday. It include alkaline and carbon zinc, mercuric-oxide, silver-oxide, zinc-air, and lithium.


Alkaline batteries
Alkaline batteries are a type of power cell dependent upon the reaction between zinc and manganese dioxide (Zn/MnO2). Alkaline batteries have a higher energy density and longer shelf-life compare to the arbon zinc batteries. They can be used in Cassettes players, radios, or appliances

Carbon zinc batteries
Carbon zinc batteries are packaged in a zinc can that serves as both a container and anode. Carbon zinc batteries are the least expensive batteries and thus a popular choice by manufacturers when devices are sold with batteries included. They can be used in remote controls, flashlights, toys, or transistor radios.

Mercuric-oxide batteries
Mercuric oxide battery is not the common battery as it content of mercury. the sale of mercury batteries is banned in many countries due to environmental concerns.

Silver oxide batteries
Silver oxide batteries have a long life and very high energy/weight ratio, but a prohibitive cost for most applications due to the high price of silver.They are available in either very small sizes as button cells where the amount of silver used is small, or in large custom design batteries where the superior performance characteristics of the silver oxide chemistry outweigh cost considerations.

Zinc-air batteries
Zinc-air batteries are electro-chemical batteries powered by the oxidation of zinc with oxygen from the air. These batteries have high energy densities and are relatively inexpensive to produce. They are used in hearing aids and in experimental electric vehicles. They may be an important part of a future zinc economy.

Lithium batteries
Lithium batteries are batteries that have lithium metal or lithium compounds as an anode. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3 V, twice the voltage of an ordinary zinc-carbon battery or alkaline cell. Lithium batteries are used in many portable consumer electronic devices, and are widely used in industry.

There are more and more batteries using in our household. A battery is an electrochemical device to convert chemical energy to electrical energy to provide power to our electronic devices. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can heavily pollute the environment when batteries are improperly disposed of.

Batteries may produce the following environmental hazards:

• Pollute the lakes and streams as the metals vaporize into the air when burned.


• Contribute to heavy metals that potentially may leach from solid waste landfills.


• Expose the environment and water to lead and acid.


• Contain strong corrosive acids.


• May cause burns or danger to eyes and skin.

So, do you wonder what you can do before buying the new batteries to prevent waste and lower the environmental impact of your hand. Here will provide some of the recommendation for you.

Buy batteries that have less mercury and heavy metals. The batteries now are reformulated to reduce the usage of mercury. Some batteries such as the alkaline battery have had about a 97 percent mercury reduction in the product. Newer alkaline batteries may contain about one-tenth the amount of mercury previously contained in the typical alkaline battery. Some alkaline batteries have zero-added mercury, and several mercury-free, heavy-duty, carbon-zinc batteries are on the market.

Try to not buy more batteries when you already have enough battery on hand. Most of the people likes to buy more batteries and store it at home but it will not be using in some time. This is a waste and will increase the risk of battery pollution in your house.

Consider using of rechargeable batteries.Rechargeable batteries has longer life span and use fewer batteries. However rechargeable batteries still contain heavy metals such as nickel-cadmium. When disposing of rechargeable batteries, recycle if possible.

Now we comes to how to recycle our used batteries. Battery is a high chemical object that we need to send to some special organization to recycle. Those organization are funded by the battery manufacturers or government to help us dispose or recycle our used battery.

Here are the websites you could check location for the recycling center or the drop off point of used batteries.

Earth 911
Earth 911 is a organization that provide information on recycling of consumer products.

Rechargeable Battery Recycling Corporation (RBRC)
Rechargeable Battery Recycling Corporation (RBRC) can help you recycle your used portable rechargeable batteries and old cell phones.
