short-circuit from the mains voltage to the output voltage) can result in
life-threatening voltages at the instrument!
Only use a battery charger that is fully functional or undamaged.
Do not charge the lithium-ion battery outside this temperature range. In
addition, the performance of the lithium-ion battery can be affected and
the service life reduced.
