Leica 18450, 18452 manual Battery can only be charged outside the camera

Notes:

•The battery can only be charged outside the camera.

•Batteries should be charged before the camera is used for the first time.

•The battery must have a temperature of 0°–35°C/32°–95°F to be charged

(otherwise the charger will not switch on, or will switch 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 more quickly.

•Lithium ion batteries should only be stored when partially charged, i.e. not when fully discharged or fully charged. For very long storage periods, they should be charged for around 15 minutes twice a year to prevent total dis- charge.

•The batteries and the charger heat 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 again 2 or 3 times. This discharge procedure should be repeated around 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 ensure a maximum service life of the battery, it should not be exposed to constant extremes (high or low) of temperature (e.g. in a parked car in the summer or winter).

•Even when used under optimum conditions, every battery has a limited ser- vice life! After several hundred charging cycles, this becomes noticeable as the operating times get significantly shorter.

•The replaceable battery provides power to a back-up battery that is perma- nently fitted in the camera. This back-up battery retains the set date and time 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 bat- tery 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, you will have to set the date and time again in this situation.

•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 (see p. 104). Otherwise, after several weeks the battery could become totally dis- charged, i.e. the voltage is sharply reduced as the camera still consumes a small amount of current (for saving your settings) even when it is turned off.
