at the end of the above charging
times, the battery should be replaced.
If

during
the charging time, the battery is considered to be
good and charging should be completed in the
normal manner.
5. It is important to remember that a completely
discharged battery must be recharged for a
sufficient number of ampere hours (AH) to
restore it to a usable state. As a general rule of
thumb, using the reserve capacity rating (RC) of
the battery as the number of ampere hours of
charge will usually bring the green dot into view.
For example, if battery is rated at 75 RC minutes,
it would be completely recharged as follows:
10 ampere charge x 7-1/2 hours = 75 AH
or
25 ampere charge x 3 hours = 75 AH, etc.
6. It is recommended that any battery recharged by
this procedure be
LOAD T E S T E D
to establish
serviceability.
JUMP STARTING IN CASE OF EMERGENCY
WITH AUXILIARY (BOOSTER) BATTERY
NOTICE:
Do not push or tow the vehicle to start.
Damage to the emission system, or to other parts
of the vehicle may result.
Both booster and discharged battery should be
treated carefully when using jumper cables. Follow the
procedure outlined below, being careful not to cause
sparks:
CAUTION: D e p a r t u r e f r o m t h e s e
c o n d i t i o n s or t h e p r o c e d u r e b e l o w

c o m p o n e n t s o f e i t h e r v e h i c l e .
Never expose battery to open flame or electric
spark - batteries generate a gas which is flammable and
explosive.
Remove rings, watches, and other jewelry. Wear
approved eye protection.
Do not allow battery fluid to contact eyes, skin,
fabrics, or painted surfaces - fluid is a corrosive acid.
Flush any contacted area with water immediately and
thoroughly. Be careful that metal tools or jumper
cables do not contact the positive battery terminal (or
metal in contact with it) and any other metal on the
car, because a short circuit could occur. Batteries
should always be kept out of the reach of children.

Set parking brake and place automatic
transmission in "PARK" (NEUTRAL for
manual transmission.) Turn
off t h e i g n i t i o n ,
t u r n o f f l i g h t s , a n d a i l o t h e r e l e c t r i c a l
l o a d s .
Check the built-in hydrometer. If it is clear or
light yellow, replace the battery.
Attach the end of one jumper cable to the positive
terminal of the booster battery and the other end
of the same cable to the positive terminal of the
discharged battery. Do not permit vehicles to
touch each other as this could cause a ground
connection and counteract the benefits of this
procedure. (Use 12-volt battery only to jump start
the engine).
Attach one end of the remaining negative cable
to the negative terminal of the booster battery,
and the other end to a solid engine ground (such
as A/C compresser bracket or generator
mounting bracket) at least 18 inches from the
battery of the vehicle being started (DO NOT
CONNECT DIRECTLY TO THE NEGATIVE
TERMINAL OF THE DEAD BATTERY).
Start the engine of the vehicle that is providing
the jump start and turn off electrical accessories.
Then start the engine in the car with the
discharged battery.
Reverse these directions exactly when removing
the jumper cables. The negative cable must be
disconnected from the engine that was jump
started first.
