provide the protection needed in a crash.
If a replacement battery is ever needed, it
must be vented in the same manner as
the original battery. Always make sure
that the vent hose is properly reattached
before reinstalling the seat cushion.To be sure the vent hose (A) is properly attached,
the vent hose connectors (B) must be securely
reattached to the vent outlets (C) on each side of
