When used correctly, batteries provide a safe and dependable source of power. However, if they are misused or abused, overheating, leakage, or in extreme cases explosion or fire, can occur.
Follow these safety principles when using batteries:
Always follow warnings and manufacturers instructions for both the batteries and the battery-operated product. Use only the correct type and size battery indicated.
Check the contacts of both the battery and the battery-operated product for cleanliness.
Always insert the batteries correctly with regard to polarity (-/+), matching the positive and negative symbols of both battery and product. Putting them in backwards, the product will sometimes still operate, but may inadvertently charge the batteries resulting in venting or leaking.
Remove and safely dispose of exhausted batteries immediately.
Replace all batteries in battery-operated products at the same time and with the batteries of the same type and manufacture.
Do not short circuit batteries. When the positive (+) and negative (-) terminals of a battery are in contact with each other, the battery can become short circuited. For example, loose batteries in a pocket with keys or coins can be short circuited possibly resulting in venting or explosion.
Do not heat batteries.
Do not crush, puncture, dismantle or otherwise damage batteries.
