Notes:
The battery can only be charged outside the camera.
Batteries must be charged before starting up the camera.
For the battery to charge, it must have a temperature of between
0°C and 35°C /32° and 95°F (otherwise the charger does not
turn on or off again).
Lithium ion batteries can be charged at any time, regardless of
their current charge level. If a battery is only partly discharged
when charging starts, it is charged to full capacity faster.
Lithium ion batteries should only be stored partly charged, i.e. not
when fully discharged or fully charged. For very long storage
periods, batteries should be charged for around 15 minutes twice a
year to prevent total discharge.
The batteries warm up during the charging process. This is normal
and not a malfunction.
A new battery only reaches its full capacity after it has been fully
charged and – by use in the camera – discharged 2 or 3 times. This
discharge procedure should be repeated every 25 cycles.
Rechargeable lithium ion batteries generate power through internal
chemical reactions. These reactions are also influenced by the
external temperature and humidity. To maximize the life of the
battery, it should not be exposed to extremely high or low
temperatures (e. g. in a parked car in summer or winter) for long
periods.
Even with optimum conditions of use, every battery has a limited
service life. After several hundred charging cycles, this becomes
noticeable as the operating times get significantly shorter.
In line with the applicable regulations (see p. 101) defective
batteries should be sent to an appropriate collection point for
proper recycling .
The replaceable battery supplies another back-up battery that is
built into the camera. This back-up battery ensures that the date
and time data entered is retained for up to 2 days. If this back-up
battery becomes discharged it must be recharged by inserting a
charged main battery. Once the replaceable battery has been
inserted, the full capacity of the back-up battery is recovered after
about 60 hours. This process does not require the camera to be
turned on. However, in this case the date and time have to be
entered again.
Remove the battery if you will not be using the camera for a long
period of time. When doing so, turn the camera off using the main
switch first. Otherwise, after several weeks the battery could become
totally discharged, i.e. the voltage is significantly reduced, as the
camera uses a low no-load current (to save the settings) even when
it is turned off.
