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. 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
cables are 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).
