CHARGE Installation & Owner’s Guide | 5
IMPORTANT SAFETY INSTRUCTIONS
h. Use charger for charging batteries only. It is not intended to supply power to a low voltage electrical
system other than in a starter-motor application. Do not use battery charger for charging dry-cell
batteries that are commonly used with home appliances. These batteries may burst and cause injury to
persons and damage to property.
i. NEVER charge a frozen battery.
12. PREPARING TO CHARGE
a. If necessary to remove battery from vessel to charge, always remove grounded terminal from battery
first. Make sure all accessories in the vessel are off, so as not to cause an arc.
b. Be sure area around battery is well ventilated while battery is being charged.
c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not
overfill. For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully
follow manufacturer’s recharging instructions.
e. Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
f. Determine amp hours or reserve capacity of battery by referring to information published by the battery
manufacturer, making sure that the app or device used to setup the CHARGE™ is set to the correct amp
hours or reserve capacity.
13. CHARGER LOCATION
a. Locate charger as far away from battery as DC cables permit.
b. Never place charger directly above battery being charged; gases from battery will corrode and damage
charger.
c. Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
d. Do not operate charger in a closed-in area or restrict ventilation in any way.
e. Do not set a battery on top of a charger.
f. Do not mount the charger below the waterline of the boat or directly adjacent to the fuel tanks.
g. Make sure that all DC output cords can reach the batteries and that the AC power cord can reach a
power source. When using an extension cord, make sure the AC connection to the charger outside of
the battery compartment is as far away as practical to reduce the risk of a spark igniting gases in the
compartment.
h. Do not shorten the DC output cords, as this can affect charger output.
i. If the DC output cords are not long enough, they may be lengthened by purchasing a JL Marine Cable
Extension Kit and following instructions contained therein.
j. Mount the CHARGE™ with at least 2 inches of space around the top and bottom of unit for proper
ventilation and cooling. While CHARGE™ has safeguards to protect batteries and circuitry, proper
ventilation will provide optimum performance.
k. Keyhole slots are not to be used for installing CHARGE™.
14. DC CONNECTION PRECAUTIONS
a. Connect and disconnect DC output terminals only after removing AC cord from electric outlet. Never
allow terminals to touch each other.
b. Attach output terminals to battery and chassis or hull as indicated in 15(e), 15(F), and 16(b) through 16(d).
