FOR THE BATTERY
Rechargeable lithium ion batteries generate power through internal
chemical reactions. These reactions are also influenced by the
external temperature and humidity. Very high or low temperatures
reduce the life of the battery.
• Always remove the battery, if you will not be using the camera
for a long period of time. Otherwise after several weeks the
battery could undergo deep discharge, i.e. the voltage is sharply
reduced, as the camera still consumes a small amount of
current (e.g. for saving the date) even when it is turned off.
• Lithium ion batteries should only be stored in a partially charged
condition, i.e. not completely discharged or fully charged (in the
corresponding display in the monitor). For very long storage
periods, it should be charged up and discharged again around
once a year.
• Always ensure that the battery contacts are clean and freely
accessible. While lithium ion batteries are proof against short
circuits, they should still be protected against contact with metal
objects such as paper clips or jewelry. A short-circuited battery
can get very hot and cause severe burns.
• If a battery is dropped, check the casing and the contacts
immediately for any damage. Using a damaged battery can
damage the camera.
• In case of noise, discoloration, deformation, overheating or
leaking fluid, the battery must be removed from the camera or
charger immediately and replaced. Continued use of the battery
results in a risk of overheating, which can cause fire and/or
explosion.
• In case of leaking fluid or a smell of burning, keep the battery
away from sources of heat. Leaked fluid can catch fire.
• A safety valve in the battery guarantees that any excess
pressure caused by improper handling is discharged safely.
• Batteries have only a limited service life. We recommend
replacing them after around four years.
• Take damaged batteries to a collection point to ensure correct
recycling.
• The batteries must not be exposed to heat, sunlight, humidity or
moisture for long periods. Likewise, the batteries may not be
placed in a microwave oven or a high pressure container as this
results in a risk of fire or explosion.
