MAS 144 Li-Ion 4I(NCM)R19/66
may only be charged using the
JLH 081 850 370G mains adapter unit.
The mains adapter unit may only be
operated with a power supply that has
an alternating current of 100–240 V~
46
and a frequency of 50–60 Hz. The use of
any other mains adapter units or the

This new type of battery has decisive
advantages over conventional Ni-Cd
batteries:
• No memory effect, i.e. regardless of
its charge status the battery can be
recharged at any time before or after
use without loss of capacity.
• Extremely low self-discharge, so it is
ready for use even after longer storage
periods.
• Light in weight
• Long service life
