Using the L 60
The accupack is being charged. The status LED
1
lights up. It is normal
for the accupack to get warm during charging.
Charging times
With a completely discharged accupack and at room temperature (approx.
20 °C/68 °F), the charging times are as follows:
However, charging may take longer under the following circumstances:
• The accupack is deep-discharged and first has to be reconditioned by a
deep discharge recovery charge.
• The ambient temperature is close to or over 35 °C/95 °F; in order to pro-
tect the accupack, the charging power will be reduced until the accupack
temperature has dropped to an admissible value.
Charging will be aborted and the status LED
1
will start flashing red under
the following circumstances:
• The accupack temperature is too low or too high (see page 122); charg-
ing starts automatically when the accupack temperature is within the
charging temperature range.
• The accupack cannot be fully charged within approx. 8 hours, e.g. due to
overaged cells.
