Batteries
Never use a charger or battery that is damaged in any way. Use the battery properly. Do

waste battery to the dealer or appointed recycle locations.
Do not dispose as household waste. Battery charging time depends on the remaining
battery charge, the type of battery, and the charger used. The battery can be charged
and discharged hundreds of times, but it will gradually wear out. When the operation
time is noticeably shorter than normal, it is time to replace the battery with a new one.
Use only original or approved chargers and batteries. Unplug the charger from the
electrical plug and the device when not in use. Do not over charge as this will damage
the battery and shorten its life. Leaving the battery in extreme hot or cold places will
reduce the capacity of the battery. Li-ion batteries are particularly affected by
temperatures below 0°centigrade.
