Via the wall plug, the accumulators can be recharged without removing them
from the multimeter.
Average charging period: 7h30 (with 2600 mAh accumulators)
with batteries
with 2200 mAh accumulators
In case of intermittent use of the multimeter, powering by Ni-MH cells is not
recommended: this type of cell has a self-discharge rate of 100 % after
3 months of non-use.
Endurances are reduced if the LCD backlight and/or the Bluetooth
communications interface is used."
