WARNING
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm. Wash hands after handling.
Allowing batteries to stand for an extended period of
time without recharging them will result in reduced
performance and service life. To preserve optimum
battery performance and life, recharge batteries in
storage when the open circuit voltage drops to 12.4
volts.
Note:
To prevent damage due to freezing, battery
should be fully charged before putting away for
winter storage.
Check the voltage of the battery with a digital
voltmeter or with the message display. If the ignition
key is turned to the “on” position for a few seconds,
the battery voltage will be displayed in the area where
the hours are normally displayed. Locate the voltage
reading of the battery in the table and charge the
battery for the recommended time interval to bring
the charge up to a full charge of 12.6 volts or greater.
Important:
Make sure the negative battery cable
is disconnected and the battery charger used for
charging the battery has an output of 16 volts and
7 amps or less to avoid damaging the battery (see
chart for recommended charger settings).
