The L 2015 quick charger
The L 2015 quick charger must only be used for automatically charging BA 2015 accupacks – individual rechargeable
battery cells or primary cells cannot be charged! The BA 2015
accupack is suitable for units of the Sennheiser ew G2, ew G3,
ew G4 series, 2000er series, the system Tourguide 1039 and
the System 2015.
The bodypack receivers (EK) and transmitters (SK) of the
Sennheiser ew G2, ew G3, ew G4 series and the System
2015 have special charging contacts, i.e. these units can be
charged with the accupack inserted. When placed into the
charger, the SK and EK automatically switch off (exception:
the EK 300 IEM G2, EK 300 IEM G3 and EK IEM G4 must be
switched off manually).
The handheld transmitters (SKM) can be charged using the
LA 2 adapter.

Charging the BA 2015 accupack
Insert the accupack 10 into one of the two charging compartments 3 as shown. The red LED 1 at the occupied
charging compartment lights up.
Charging a completely discharged accupack takes approx.
2½ hours at room temperature. It is normal for the accupacks to get warm during charging.
After the accupack has been fully charged, the green LED

• the ambient temperature is close to or over 40 °C, since,
conditioned by a deep discharge recovery charge,
in order to protect the accupack, the charging process will
be interrupted until the accupack temperature has fallen

If a problem occurs
If a problem occurs
If a red LED starts flashing, one of the following errors has
occurred at the corresponding charging compartment:
Possible cause Possible solution
No contact with the accupack (contacts are dirty or
accupack is not inserted
correctly)
Accupack is defective (overaged or defective rechargeable battery cells)
Accupack temperature is too
low or too high
Batteries (primary cells) or
individual rechargeable batteries have been inserted
Clean the contacts or insert
the accupack correctly.
Replace the accupack.
Always charge the accupack
