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 Recycle Button Cell Batteries:

Button cell batteries are round, between 5 and 12 mm in diameter and commonly found in watches, hearing aids and calculators. According to the Mercury Education and Reduction Campaign, mercury was removed from alkaline batteries in 1996, but not from button cell batteries. If incinerated or left in landfills, mercury and other toxins can leak out and enter water supplies and food chains. Therefore, button cell batteries should be recycled and not put into the regular trash.

• Remove the dead button cell battery from your watch or other electronic device. Store the battery in a place where damage won't occur before recycling. If bringing your item to a store for battery replacement, it is fine to leave the battery in.
• Bring your dead battery to your nearest watch store. Since they replace batteries often, your watch retailers may have recycling through their store.
• Check with your local recycling facility. They may not allow for curb pick-up of batteries, but they might have battery recycling on site.
• Head to your nearest Home Depot, Battery Center or Ace Hardware with your dead batteries. These retailers and others let customers drop off batteries in store to be recycled. Visit Call2Recycle's website (see Resources) to find the nearest retail location for recycling your button cell batteries. It is always a good idea to check with the retailer first as not all locations may participate.
• Watch for hard-to-recycle events in the surrounding municipalities in your area, especially popular in the spring when everyone does the big spring cleaning. Batteries might be one of the items they will take for free or for a small fee depending on the particular city.
