PREPARING TO CHARGE
13. 
a) 
If necessary to remove battery from vehicle to charge, always remove grounded 
terminal from battery first. Make sure all accessories in the vehicle 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 bat-
tery manufacturer. Do not overfill. For a battery without removable cell caps, such 
as valve regulated lead acid batteries, carefully follow manufacturer's recharging 
instruction. 
e) 
Study all battery manufacturer's specific precautions while charging and recom-
mended rates of charge.
f) 
Determine voltage of battery by referring to car owner's manual and make sure 
that the output voltage selector switch is set at correct voltage. If charger has 
adjustable charge rate, charge battery initially at lowest rate.
CHARGER LOCATION
14. 
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 grav-
ity 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 charger.
DC CONNECTION PRECAUTIONS
15. 
a) 
Connect and disconnect dc output clips only after setting any charger switches to 
"off" position and removing ac cord from electric outlet. Never allow clips to touch 
each other.
b) 
Attach clips to battery and chassis as indicated in 16(e), 16(f), 17(b) through 17(d).
FOLLOW THESE STEPS WHEN BATTERY 
16. 
IS INSTALLED IN VEHICLE. A SPARK 
NEAR BATTERY MAY CAUSE BATTERY
