Notes:
• The battery must have a temperature of +10° to +30°C (50° to
86°F) to be charged (otherwise the charger will not turn on, or
will turn 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.
• A new battery only reaches its full capacity after it has been ful-
ly charged and – by use in the digital back - discharged again
2 or 3 times. This discharge procedure should be repeated
roughly every 25 cycles.
• Both battery and charger become warm during charging. This
is normal and not a malfunction.
• If the two LEDs flash rapidly (faster than twice per second)
after the start of charging, this indicates a charging error (e.g.
maximum charging time exceeded, voltages or temperatures
outside the permitted ranges, or short circuit). In this case,
disconnect the charger from the mains and remove the battery.
Ensure that the above temperature conditions are met and
then restart the charging process.
• If the problem persists, please contact your dealer, the Sinar
dealer in your country or Sinar Photography AG.
• Lithium ion batteries should only be stored partly charged, i.e.
not when fully discharged or fully charged. For very long stor-
age periods, you should charge the battery for approx. 15 min-
utes roughly twice a year to avoid a deep discharge.
• Rechargeable lithium ion batteries generate power through
internal chemical reactions. These reactions are also influ-
enced by the ambient temperature and humidity. To ensure a
maximum service life of the battery, it should not be exposed
to constant extremes of temperature (e.g. in a parked car in the
summer or winter).
• Even when used under optimum conditions, every battery has
a limited service life! After several hundred charging cycles,
this becomes noticeable as the operating times become sig-
nificantly shorter.
• Dispose of damaged batteries in accordance with the relevant
regulations (see p. 6, 56) at an approved collection point for
proper recycling.
• The replaceable battery provides power to a back-up battery
which is permanently fitted in the Sinarback. This back-up
battery retains the set time and date for up to 3 months. 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 Sinarback to be turned on. In this case, however, the time
and date have to be set again.
• Remove the battery if you will not be using the camera for a
long period of time. When doing so, turn the Sinarback off
using the main switch first. Otherwise after several weeks
the battery could undergo deep discharge, i.e. the voltage
is sharply reduced, as the Sinarback still consumes a small
amount of current (e.g. for saving your settings).
