The document provides instructions for jump starting a car with a dead battery using another car as a power source. It begins by explaining battery basics, such as the function of the battery, signs of a weak battery, and positive and negative terminal identification. It then outlines the step-by-step process to safely jump start the dead car, including connecting the positive clamps first and negative clamps last, revving the working car's engine, and starting the dead car. Tips are also provided on what to do if the battery is very dead and potential causes of a dead battery.

2. Battery Basics I
 The battery provides electrical power to
help start the car
 A battery is good for about 4-5 years
 After that you are risking trouble
 Green ball indicator
 Rough indicator that the battery is OK
 12.2-12.6 volts is the good range for
most batteries
 Below 12 volts is probably trouble

3. Battery Basics II
 The battery has a positive and a
negative terminal
 The positive terminal = red cable = “+” sign
 The negative terminal = black cable = “-”
sign
 Battery cables should be connected
firmly to the terminals
 Terminals and battery clamps should be
relatively clean
 Batteries can be dangerous

4. Inspect the battery
physically

5. Use secure cables

6. Before You Begin
 Be sure to have jumper cables!
 Bring “jumper” car close to the car with
the dead battery
 Cars should not be touching!
 The jumper cables should be relatively
clean
 Turn off cars and all accessories on
both cars
 If you can, measure the battery voltage

7. Park working car in front of
dead battery car

8. Turn off functional car
battery.

9. Think Positively
 First identify the positive post on each
battery
 The positive post usually has a “+” sign on
it (or red cable)
 The safest battery is the dead battery
 So start there
 Put the red clamp on the + post of the dead
battery
 Then put red clamp at the other end on the
+ post of the good battery

10. Note terminals positions
(Positive and Negative)

11. Connect both ends of
jumper cables on the same
signs of both batteries

12. Halfway there!
 + is done
 While you are at the good battery,
attach the black clamp to the negative
(-) post
 Attach black clamp at the other end to a
solid metal part of the dead car’s engine
away from the battery
 Start the good car!

13. Solid metal part of the dead
car’s engine

14. Start charged battery’s car
engine.

15. Finishing up!
 Rev up the “jumper” car a little bit (to
get the alternator running)
 Let the car fast idle for about 30
seconds or so
 If the battery is super dead it needs a little
extra charge
 Start the dead car!
 Reverse the process to release the
clamps (-D  -G  +G  +D)

16. Things to Watch For
 Battery voltage is below 9.5 volts or no
green ball
 Might be better to charge it separately
 High-voltage starting kits may cause the
voltage to go above 17 volts which can
damage electronics/computers in car
 Find out why the battery died
 Lights
 Wiring, loose fan belt, diode in the
alternator, bad grounds, bad battery cable
connection…
