temperature range has been reached again. The charging time is
typically 4 hours. A new NiMH power pack reaches its full capacity
after three complete charge / discharge cycles. Never store the
instrument for extended periods without being connected to a power
source (maximum of 2 months) because the internal buffer battery will
drain.
