Battery Storage
Refer to Safety Precautions on page 146.
If you plan to store your PWC, we
recommend you remove the battery and store
it where it can be charged at least every 30
days to maintain its service life.
If you do not remove the battery, we
recommend disconnecting the battery cables
(negative cable first) .
You will get the best storage results from
removing the battery and slow (trickle)
charging it every 30 days (see Battery
Charging, page 204) .
Before you remove the battery, be sure to
read all the information that follows. After
removing the battery, be sure to read the
information on the battery label.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a face
shield, or have a skilled mechanic
do the battery maintenance.
