Precautions
Observe the following precautions when handling and charging the
batteries:
• Do not attempt to use or charge the batteries when they are exposed to
temperatures below –10º C (15º F) or above 40º C (105º F). (Most
batteries of this type have an internal safety device that prevents
them from operating outside of this temperature range.)
• Charge the batteries only with a charger intended for this type of
battery or inside the Counter.
• Do not allow the battery terminals to contact any conductive surfaces.
• Avoid discharging the batteries completely.
• Recharge the batteries as soon as possible after use.
• Handle the batteries carefully to avoid internal damage and/or
damage to the casings. Do not drop or throw the batteries or otherwise
expose them to strong physical shock.
• Do not incinerate the batteries or subject them to extremely high
temperatures.
