of battery may present a fire hazard if used with other
batteries.
2. When the battery is not in use, keep it away from
paper clips, coins, keys, nails, screws, or other small
metal objects that could cause the contacts to be
bridged. A short circuit between the battery contacts
can result in burns or fire.
3. If used incorrectly, liquid can leak out of the battery.
Avoid contact with it. In the event of accidental
contact with water, rinse. If the liquid gets into your
