unplugged. Never allow clamps to touch each other.
b. Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of
the battery.
c. Position yourself and free end of cable as far away from battery as possible - then
connect the NEGATIVE (BLACK) charger clamp to free end of cable.
d. Do not face the battery when making the final connection.
e. When disconnecting the charger, always do so in the reverse sequence of connecting it
and take off the first connection as far away from the battery as practical.
f. A marine (boat) battery must be removed and charged on shore, charging it on board
requires specially designed equipment, for marine use.
AC POWER CORD CONNECTION INSTRUCTIONS:
DANGER. Never alter the AC cord or plug provided - if it will not fit the outlet, seek
professional advice from a qualified electrician. Improper connection can result in a risk of
electric shock.
LENGTH OF CHARGE
The following instructions will allow you to determine how long it will take to bring your battery
to full charge.
a. Test the battery's charge with a hydrometer or electronic tester.
b. Determine the size of the battery in Amp-Hour or Reserve Capacity. If the ratings are not
printed on the battery, contact your local battery dealer for this information. These are the
only ratings that can be used to determine charge time.
c. Use the battery's rating and charge level, together with the amp setting to be used on the
charger in the formula below:
Amp Hour Rating of Battery × Percent of Charged Needed
Amp Setting Selected On Charger
NOTE: Charge times are approximate and vary from battery to battery. Always follow the
battery manufacturer's specific charging instructions.
