How do Duracell batteries affect the environment?

In 1993, we voluntarily eliminated added mercury from our batteries. “Our alkaline batteries are composed of primarily common materials—steel, zinc, and manganese—and do not pose a health or environmental risk in normal use or disposal. What’s more, we are going green by eliminating PVC clamshells and replacing them with high-fiber content cards and RPET (Recycled PET) blisters. This is a complete, sustainable packaging solution, one of the best PVC alternatives available today. As the world’s leading manufacturer of high-performance alkaline batteries, we recognize our responsibility to help protect the environment. We’re committed to designing, manufacturing, and distributing batteries in a way that minimizes impact to the environment. We also participate in the Call2Recycle program to ensure the safe and proper recycling or disposing of batteries.”

My child likes to play with batteries. Is this ok?

Young children should not play with batteries. Batteries are made to power devices, not to be played with individually. Remember that while batteries are popular, commonplace devices, they generate portable power by means of potent chemical reactions. Batteries should never be disassembled, abused, mishandled, or treated as toys. Although most batteries contain chemicals that won’t harm exposed skin, they should still be treated as any chemical would. Always take precautions when handling exposed battery chemicals. Battery chemicals shouldn’t be placed near the eyes or ingested. Contact a physician immediately if this should occur. To assure safety, use of batteries by children should be closely monitored by a responsible adult.

Who invented the battery?

In the 1860s, George Leclanche of France developed what would be the forerunner of the world’s first widely used battery; the zinc carbon cell. The anode was a zinc and mercury-alloyed rod (zinc, the anode in Alessandro Volta’s original cell, proved to be one of the best metals for the job). The cathode was a porous cup of crushed manganese dioxide and some carbon. Into the mix was inserted a carbon rod to act as the current collector. Both the anode and the cathode cup were plunged into a liquid solution of ammonium chloride, which acted as the electrolyte. The system was called a “wet cell.” Though Leclanche’s cell was rugged and inexpensive, it was eventually replaced by the improved “dry cell” in the 1880s. The anode became the zinc can containing the cell, and the electrolyte became a paste rather than a liquid; basically the zinc carbon cell that is known today.

What is inside a battery?

Batteries may be small, but they’re far from simple. They’re highly engineered electrochemical cells. Chemical energy is converted to electrical energy by a redox reaction. This process takes place between the three major parts of a battery: the anode, cathode, and electrolyte. Different types of batteries use different materials for these parts. The materials for these parts are chosen depending on how well they give up or attract electrons, something that must happen for an electric current to be generated. The anode is often a metal, the cathode is a metallic oxide, and the electrolyte is a salt solution that facilitates the ion flow.

Do all batteries last the same amount of time?

No, different batteries provide different lengths of life and power output, depending on the type and amount of chemicals used to compose them. Think of it like cooking a meal: Using different ingredients and amounts make the meal taste different.

How does a battery work?

Batteries may seem simple, but the delivery of packaged power is a complicated electrochemical process. Electric current in the form of electrons begin to flow in the external circuit when the device—a light bulb for example—is turned on. At that time, the anode material, zinc, gives up two electrons per atom in a process called oxidation, leaving unstable zinc ions behind. After the electrons do their work powering the light bulb, they re-enter the cell at the cathode, where they combine with the active material, manganese dioxide, in a process called reduction. The combined processes of oxidation and reduction couldn’t occur in a power cell without an internal way to carry electrons back to the anode, balancing the external flow of current. This process is accomplished by the movement of negatively charged hydroxide ions present in the water solution called the electrolyte. Every electron entering the cathode reacts with the manganese dioxide to form MnOO-. Then, MnOO- reacts with water from the electrolyte. In that reaction, the water splits, releasing hydroxide ions into the electrolyte and hydrogen ions that combine with MnOO- to form MnOOH. The internal circuit is completed when the hydroxide ions produced in this reaction at the cathode flow to the anode in the form of ionic current. There, they combine with unstable zinc ions, which were formed at the anode when the electrons were originally given up to the external circuit. This produces zinc oxide and water. This completes the circuit (which is necessary to have a constant flow of electricity) and powers your flashlight.

Do I have to change all the batteries at the same time?

We do recommend changing all batteries in a unit at the same time. A partially used battery will drain energy from a new one, reducing the total amount of battery power available.

Show / hide

Can I mix old and new batteries?

Do not mix old and new batteries. Doing so will reduce overall performance and may cause battery leakage or rupture. We recommend replacing all batteries within a device.

Show / hide

Can I mix different battery types?

No, different batteries are designed for different purposes. Mixing a lithium battery with an alkaline battery will not improve device performance. In fact, it will reduce performance and may even damage your device or cause battery leakage or rupture. As well, do not mix different battery brands within a device. Doing so will reduce overall performance and may also cause battery leakage or rupture. We recommend using the same type of batteries within a device.
