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 Recharge Button Cell Batteries?

Button cell batteries are known for their small features. These thin energy cells are used to provide battery power for hearing aids, electronic devices and watches. They require a very thin profile, allowing gadgets to benefit from their compact nature and style. Most people buy new button cell batteries whenever their old ones run out of power. However, it is possible to recharge your button cell batteries without seeking the help of a professional. Recharging batteries, versus buying new ones, will save you money.

Instructions:

For Cyclic or Fast Charging:

• Insert your battery into the open slot of the button cell battery charger. Use clear tape to seal it in place if the battery does not fit tightly into the charger
• Switch on the charger's power button and charge the cell battery until it reaches the terminal voltage of 2.40 to 2.45 volts per cell at 58 degrees Fahrenheit. This is equivalent to 14.4 to 14.7 volts for a 12-volt battery, with a temperature of 20 degrees Celsius, and will place your button cell batteries on cyclic or fast charging
• Leave your battery on this voltage until the dial shows a charge current of 0.01 x C amps. Most battery amp-hour rating is at C
• Turn off the battery charger and remove the newly charged button cell battery

For Standby Service or Float Charging:

• Insert your battery into the open slot of the button cell battery charger. Use clear tape to seal it in place if the battery does not fit tightly into the charger
• Switch on the charger's power button and set it on float charging mode. Charge the button cell battery at a continuous voltage of about 2.25 to 2.30 volts per cell at 58 degrees Fahrenheit. This is equivalent to 13.5 to 13.8 volts for a 12-volt battery, with a temperature of 20 degrees Celsius. The charger will regulate your button cell batteries into its own current level
• Turn off the battery charger as soon as the button cell batteries are completely charged. You can check the dial to determine the status of the battery's charge. Remove the battery from the charger.

Package Included:

• 5 x Button Cell Batteries
