Battery Precautions - Casio GEC-10 User Manual

Battery Precautions

. Precautions During Use
• Operation provided by a battery under cold conditions is always less than operation
under normal temperatures. This is due to the characteristics of the battery, not the
product.
• Charge the battery in an area where the temperature is within the range of 15°C to
35°C (59°F to 95°F). Outside this temperature range charging can take longer than
normal or even fail.
• If the battery provides only very limited operation following a full charge, it probably
means it has reached the end of its service life. Have the battery replaced with a
new one. Contact your retailer or a CASIO authorized service center to have the
battery replaced. Do not try to replace the battery yourself.
. Storage Precautions
• Storing the battery for a long time while it is charged can cause deterioration of
battery characteristics. If you do not plan to use a battery for some time, fully use
up its charge before storing it.
• Store batteries in a cool, dry place (20°C (68°F) or lower).
• To prevent over discharging of an unused battery, fully charge it, and then fully use
up the charge about once every six months.
