The internal battery
Your M60 stores the energy in a latest-generation high-quality recharbeable
Lithium-Ion battery. The energy storage capacity of the battery is indicated in
Wh (watt hours).
Due to natural ageing the battery loses capacity over time. In order to delay
this process as much as possible, the battery is electronically monitored and
protected from excessive strain. In many cases this may extend the life of
battery even beyond the time indicated by the manufacturer. It cannot be
excluded, however, that the battery may age much faster in cases.
The following recommendation will ensure a longer life of your battery:
Do not expose the battery to temperatures above 20°C during a
longer period. Otherwise there is the danger of premature ageing.
When storing the M60 for a longer time, make sure it has been
switched off and that the battery has the appropriate charging level
(70%). Risk of over-discharge! Please find more about recommended
storage conditions in the Technical data section.
To minimize the risk of over-discharge connect a thinfilm solar panel
(3Wp is good enough) to M60. Ensure that the M60 is switched on
and that there is sufficient daylight for the panel.
The internal battery is cadmium free.
Do not use or store the M60 in an incorrect way or open the
housing. Otherwise your limited warranty will become void.
Please note the recommendations about disposal of the internal
battery!
Several electronic safety stages in your M60 protect the battery against over-
load and overcurrent and as far as possible against excessive discharge. Howe-
ver, since Lithium-Ion batteries are self-discharging, complete over-discharge
protection is not possible. If the battery is damaged due to the excessive
discharge, the safety system will switch off the M60 permanently, until the
battery has been replaced. There is no warranty for over-discharge!
