Button Battery Types:
- Button batteries, also known as button cell batteries, are small, flat, round batteries designed for use in wristwatches, pocket calculators, hearing aids, cameras, TV remote controls and other electronic devices. Most button batteries have an anode (the negative part of the battery through which electrical current flows) a separator (the material that contains electrolyte, which is an electrical conductor) and a cathode (the positive part of the battery).
- Alkaline Batteries: Alkaline batteries, or alkaline cells, are mainly used because they are inexpensive. They are similar to lithium cells but are used in devices that are inexpensive, such as a cheap watch as compared to an expensive one. They are inexpensive to manufacture and are safe for the environment. However, alkaline batteries only have about half the energy capacity of silver oxide batteries, voltage that is not constant and a short shelf life. They are best used in devices such as in quartz watches, miniature flashlights and laser pointers.
- Mercury Batteries: Mercury batteries, also known as mercury cells, are no longer used in many countries because they are known to contaminate water and food sources when they are disposed of. The mercury that leaks from these batteries is highly toxic to living organisms, including humans. These batteries have a long life and can be stored, unused, for up to three years. Mercury batteries were used in almost all devices that required small, constant voltage such as watches, hearing aids and calculators.
- Silver Oxide Batteries: Silver oxide batteries, or silver oxide cells, are constructed similarly to mercury cells and are the successor of mercury batteries. They are better than mercury batteries because they have a higher energy capacity and do not contain any chemicals that are harmful to the environment. Like mercury batteries, silver oxide batteries have a long life. The only disadvantage is that silver oxide batteries have about half the shelf life as mercury batteries. This type of battery is mainly used for watches.
- Lithium Batteries: Lithium batteries, or lithium cells, are also called coin cells because of their shape. Lithium-manganese dioxide and lithium-thionyl chloride are the two types of lithium batteries. Lithium-manganese dioxide cells are used in watches while lithium-thionyl chloride cells are not intended for use in watches. They both have a constant voltage and, like silver oxide batteries, don't contain any chemicals that are harmful to the environment. Lithium batteries have an especially long shelf life of up to 10 years and are suitable for devices such as quartz watches, digital cameras and remote controls.
- Zinc-air Batteries: Zinc-air batteries, or zinc-air cells, have the highest energy capacity of all button batteries. They are activated when a seal is pulled off, which allows air to enter the battery through small holes, thereby allowing oxidation of zinc. They are inexpensive, have a constant voltage output and are environmentally safe. Zinc-air batteries have a considerably shorter shelf life than mercury batteries but a longer shelf life than alkaline and silver oxide batteries. This type of battery is not meant to be used in watches but rather in hearing aids.
How to Test a Button Battery?
- Button batteries are small batteries that are usually used to power small electronic devices. They get their name because they are round and resemble buttons or coins. Many people are unfamiliar with this relatively new type of battery. If you have an electronic device that has stopped working, it may be a simple matter of a dead or dying button battery. There is a testing method for button batteries that will allow you to check their condition.
- Remove the battery from the device and inspect it to determine the battery voltage. The voltage will be marked on the battery. Most button batteries are between 1.35 and 3 volts.
- Set the multimeter so that it displays voltage on the DCV scale.
- Determine the positive side of the battery by finding the side with a "+" marked on it. Touch the positive probe (red) of the multimeter anywhere on this side.
- Touch the negative probe (black) of the multimeter to the negative side of the battery, which is of course the opposite side from the positive side.
- Take note of the displayed voltage on the multimeter. If it is 10 percent (or more) less than the marked voltage on the battery, replace the battery as recommended on BobVila.com. For example, a 1.5 volt battery should show a voltage of at least 1.35 volts, and a 3 volt battery should show a voltage of at least 2.7 volts.
How to Recycle an Alkaline Battery:
- Alkaline batteries are a necessity in small electronics such as television remote controls, toys or flash lights and they produce about 1.5 volts per cell. The larger cell batteries such as C and D batteries can deliver more currents. The recharging of alkaline batteries is possible but very uncommon creating the need for recycling of these alkaline batteries. Many areas have started or put into effect safe recycling projects.
- Determine if there are rules for recycling alkaline batteries. In some states and counties alkaline batteries can be disposed of in your regular trash. In the state of California this would be illegal.
- Contact your local grocery store and ask if they have a drop off area for alkaline batteries. Some grocery food chains collect batteries in large bins right outside the store door. Ask the manager if there are any special rules or if you can just toss your used batteries in the bin.
- Recycle alkaline batteries at your local dump. Most local dumps will accept alkaline batteries.
- Purchase a recycle container for your used batteries. There are many local companies that sell these containers in several sizes. You fill the container with your used batteries and return the container to the company for recycling.
Tips & Warnings:
- Avoid exposure to high temperatures and do not dispose of alkaline batteries in fire.
- Do not misuse your battery; it can result in the battery leakage.
