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. 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. At that time, the anode material, zinc, gives up two electrons per atom in a process called oxidation, leaving unstable zinc ions behind. Is this normal?īatteries may seem simple, but the delivery of packaged power is a complicated electrochemical process.Įlectric current in the form of electrons begins to flow in the external circuit when the device-a light bulb for example-is turned on. DON’T – Remove the battery label, or attempt to take the battery apart, or dispose of in a fire as this may lead to rupture and/or chemical burns.Extreme temperatures reduce battery performance and may also lead to leakage. DON’T – Put batteries or battery-powered devices in very warm places.Where there are collection programs for used batteries in your area, store used batteries in a non-metal container in a well ventilated area, do not mix the batteries with other items, and bring to the collection facility on a regular basis. DON’T – Dispose of large numbers of batteries at one time.This will not ‘recharge’ your batteries, increase storage life, or increase your batteries’ power. DON’T – Place your batteries in a refrigerator.This can cause your batteries to overheat or leak. DON’T – Attempt to recharge non-rechargeable batteries.DON’T – Mix old and new batteries, batteries of different brands, or batteries of different types (for example heavy duty zinc chloride batteries and alkaline batteries) in the same device as this may cause the batteries to leak.They can be shorted by contact with metal objects and may leak, overheat or rupture. DON’T – Carry batteries loose in your pocket or purse as they may create a safety risk.Many devices don’t power off completely when switched off and, after time, may cause the batteries inside to leak. DON’T – Leave batteries in your device if you suspect it will not be used for several months.DO – Remove batteries from equipment while it is being powered by household alternating current (except for hardwired smoke alarms that use back up alkaline batteries).You can contact your local government for information about the disposal options in your area or utilize the following website. DO – Where possible, recycle your batteries where communities offer recycling or collection programs.DO – Keep all batteries in a safe place away from children and pets, particularly the smaller sized batteries.This will help prevent damage to the battery or device. DO – Insert batteries by placing the negative end in first, then push the battery down so the positive end clicks into place.CAUTION: Some equipment using more than three batteries may appear to work properly even if one battery is inserted incorrectly. Insert batteries properly, with the plus (+) and minus (–) terminals aligned correctly. DO – Replace all used batteries in your device at the same time.DO – Store batteries, in their original packaging, in a dry place and at normal room temperature until ready to use.DO – Use the correct size and type of battery specified by the manufacturer of your device.Some devices may continue to draw power from exhausted batteries which may cause the batteries to leak. DO – Remove batteries from the device as soon as possible after they are depleted.
