Leica 18430 Manuel D’Utilisation

110

• 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.
