• If the batteries do leak, avoid contact with the leaked fl uid. If the
battery fl uid should come in contact with your eyes, mouth, or skin,
wash immediately with water and consult a doctor. Battery fl uid is
corrosive and may possibly cause loss of sight or chemical burns.
• When using rechargeable batteries, follow the instructions that came
with the batteries. Use only the specifi ed charger device and within
the specifi ed charging temperature range when charging. Charging
with an unspecifi ed charger or at a temperature outside the range
may cause leakage, overheating, explosion, or malfunction.
• Keep batteries away from children. A child could accidentally swallow
a battery. Failure to observe this may also cause infl ammation due to
battery fl uid leaks.
• Do not put batteries in a pocket or bag, or carry or store them togeth-
er with pieces of metal. Batteries kept in such condition could short,
burst, or leak, causing a fi re or injury.
