PREPARING YOUR BATTERY TO BE CHARGED
It is important that you read and follow these guidelines while you are preparing to
charge your battery.
• Make sure that you have a 12 volt
lead-acid battery.
• Clean the battery terminals. Be
careful to keep corrosion from getting
in or around your eyes.
• For batteries with removable vent
caps, if required, add distilled water to
each cell until the battery acid
reaches the level recommended by
the manufacturer. This will help purge
excessive gases from the cells. Be
careful not to overfill. If you have a
sealed battery with non-removable
vent caps, no action is necessary.
• Take time to read all battery
manufacturer’s specific precautions,
such as removing or not removing
vent caps while charging, and
recommended rates of charge.
• Wear safety glasses. See additional
"Personal Safety Precautions" on
page 4.
• Be sure that the area around the
battery is well ventilated while it is
being charged.
• If it is necessary to remove the battery
from the vehicle to charge it, always
remove the grounded terminal from
the battery first. Turn off all vehicle
accessories to avoid sparks from
occurring.
NOTE: A marine battery installed in a
boat must be removed and charged on
shore.
Read the following pages before using your charger. The tips below serve only as a
guide for specific situations.
operate your vehicle, you don’t need to
wait for the entire charging process to
be completed. When the charger
displays three Battery Status LEDs (see
pages 8, 9, and 12), the battery has
been charged as much as by most
chargers. The vehicle should then start
and operate normally.
Completing an interrupted charge: If
the charging process has been inter-
rupted and restarted after three Battery
Status LEDs were lit, the charger will
go straight to Maintain Mode (see
pages 7 & 9). However, if the original
charge was started using 15 Amps, the
charge can often be completed using 2
Amps.
CHARGING TIPS
If your vehicle won’t start: You don’t
need to fully charge a battery to start
your vehicle. If the charger won’t start
your vehicle using the 100 Amp Start
rate, try charging the battery using the
15 Amp rate for 10 or 15 minutes. That
should charge the battery enough to
allow the 100A Start rate to start the
vehicle. If the vehicle will then be
operated continuously for an extended
period (such as a long drive), the
vehicle could charge the battery back to
normal during that period. If the vehicle
will only be operated for a short period
(short drive), the battery might need to
be charged again before it could start
the vehicle.
Reviving your battery: If you only
