6.2 Charging the battery
The charging time depends on various factors,
e.g. the battery temperature or the ambient tem‐
perature. For optimum performance, observe the
recommended temperature ranges, 20.6. The
actual charging time may vary from the charging
time indicated. The charging time is indicated at
