GOOD HOUSEKEEPING UK HAS BEEN QUOTED AS SAYING THAT YOU SHOULDN’T USE RECHARGABLES IN SMOKE ALARMS. IS THIS CORRECT?

Good Housekeeping rationale: “when rechargeable batteries run out of power, they do so very quickly, whereas disposable alkaline batteries tend to ‘die’ slowly. This means you won’t get the warning beeps that tell you when the battery in your smoke alarm needs changing if you use rechargeables.” Due to its safety nature, the smoke alarm is not an ideal device for standard rechargeable batteries. Indeed standard rechargeable batteries discharge with time, and this means that for essential safety devices such as a smoke alarm, it is not recommended. We also need to remember that even if disposable batteries are used in smoke alarms, it is highly recommended to change the battery a minimum of once a year. Still can’t find what you’re looking for?

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.

What is an alkaline battery?

Duracell pioneered the Alkaline Manganese Dioxide electrochemical system nearly 40 years ago. In the 1960s, this battery system rapidly became the popular choice of designers in the ever-widening field of consumer electronics. Alkaline or Alkaline Manganese Dioxide cells have many advantages over zinc-carbon cells including up to ten times the ampere-hour capacity at high and continuous drain conditions. Also, its performance at low temperatures is superior to other conventional aqueous electrolyte primary cells. Other significant advantages are longer shelf life, better leakage resistance, and superior low-temperature performance. Its more effective, secure seal provides excellent resistance to leakage and corrosion. Today, Duracell manufactures three alkaline batteries: Ultra Power, Plus Power and Simply.

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.
