3.4 Add distilled water in each cell until battery acid reaches level specied
by battery manufacturer. Do not overll. For a battery without removable
cell caps, such as valve regulated lead acid batteries, carefully follow
manufacturer’s recharging instructions.
3.5 Study all battery manufacturer’s specic precautions while charging and
recommended rates of charge.
4. CHARGER LOCATION
4.1 Locate charger as far away from battery as DC cables permit.
4.2 Never place charger directly above battery being charged; gases from battery
will corrode and damage charger.
4.3 Never allow battery acid to drip on charger when reading electrolyte specic
gravity or lling battery.
4.4 Do not operate charger in a closed-in area or restrict ventilation in any way.
4.5 Do not set a battery on top of charger.
5. DC CONNECTION PRECAUTIONS
5.1 Connect and disconnect DC output clips only after removing unit from electric
outlet. Never allow clips to touch each other.
5.2 Attach clips to battery and chassis, as indicated in sections 6 and 7.
6. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE
WARNING! A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
6.1 Position AC and DC cords to reduce risk of damage by hood, door, or moving
engine part.
6.2 Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to
persons.
6.3 Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually
has larger diameter than NEGATIVE (NEG, N, –) post.
6.4 Determine which post of battery is grounded (connected) to the chassis.
If negative post is grounded to chassis (as in most vehicles), see (6.5). If
positive post is grounded to the chassis, see (6.6).
