compartment lights up.

lights up.
Notes:
y Charging a completely discharged accupack takes
approx. 3½ hours at room temperature. It is
normal for the accupacks to get hot during
charging.
y However, the charging process may take longer
if:
– 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
40°C, since, in order to protect the accupack, the
charging process will be interrupted until the
temperature has dropped to a safe level.
y For safety reasons, each charging process will be
interrupted after 4 hours.
y When not using the BA 2015 accupack for
extended periods of time, charge it about every
three to six months.
