PEUGEOT Boxer Handbook page 149

The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a PEUGEOT dealer or
a qualified workshop is essential when
replacing or disconnecting the battery.
Failure to observe this recommendation may
cause premature wear of the battery.
After refitting the battery by a
PEUGEOT dealer or a qualified
workshop, the Stop & Start system will
only be active after a continuous period of
immobilisation of the vehicle, a period which
depends on the climatic conditions and the
state of charge of the battery (up to about
8 hours).
Do not disconnect the battery to
charge it.
