Battery use
● Never use any charger or battery if damaged. Use the battery correctly.
● Do not short-circuit the battery, as this may damage it or cause a fire.
● Do not subject the battery to high temperatures or fire as it may explode.
● Return the old battery to your dealer, or place it in locations designated for
recycling.
● Do not throw the battery in household waste.
● Charging time depends on remaining battery charge, type of battery and charger
used.
● Battery can be charged and discharged hundreds of times, but its duration will
gradually decrease.
● When operation time is noticeably shorter than normal, replace the battery with
a new one.
● Use only original chargers, batteries and accessories approved by the
manufacturer.
● Disconect the charger from the plug and the device when not being used.
● Do not overload your battery as it may damage or shorten its lifecycle.
