An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Vauxhall battery.
Note
Using an AGM battery different from
the original Vauxhall battery might
result in a lower performance of the
stop-start system.
9 Warning
When fitting a battery with a length
deviating from the original one, it
is essential to ensure a proper
fitting of the buffer element.
We recommend that you have the
battery replaced by a workshop.
