Tips for Battery Care and Use: DO ? Keep all batteries in a safe place away from children and pets, particularly the smaller sized batteries. 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. DO ? Store batteries, in their original packaging, in a dry place and at normal room temperature until ready to use. DON?T ? Attempt to recharge non-rechargeable batteries. This can cause your batteries to overheat or leak. DO ? Use the correct size and type of battery specified by the manufacturer of your device. DON?T ? Carry batteries loose in your pocket or purse as they may create a safety risk. They can be shorted by contact with metal objects and may leak, overheat or rupture. DO ? Replace all used batteries in your device at the same time. Insert batteries properly, with the plus (+) and minus (?) terminals aligned correctly. CAUTION: Some equipment using more than three batteries may appear to work properly even if one battery is inserted incorrectly. 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. DO ? Where possible, recycle your batteries where communities offer recycling or collection programs. You can contact your local government for information about the disposal options in your area.
