I am looking to purchase either a 600 or 900 amp battery charger (Peak) and I can't decide which is better. It is to start a dead or dying battery on the road without a jump from another person or vehicle.
The most important consideration when purchasing a jump starter is power. How much power is the jump starter getting to the battery? Many manufacturers only offer battery booster packs that have only 900 peak amps and maybe 200 cranking amps.
Starter motor problems, charging system problems, wiring and connection problems between battery, alternator and starter. To many possiblities to list. If the battery is still charged and you need to jump the car to get it to start you have a bad starter. Now you say how can that be? it starts when its jumped? Correct the starter is drawing too much power"amps" and having a second battery "the jump" appx doubles the amount of amps to the starter allowing it to start. Replace the starter and problem will go away. Besides it wont take too long before a jump wont allow it to start.
That depends on several factors: If the car battery is FULLY discharged, a starter can pull as much as 200 AMPS when you try to start the engine, depending on the size of the engine. If the car battery is only "low", but still carries a pretty good charge, you might be able to get by with considerably less than 200 AMPS.
To answer this question a voltage needs to be stated. Amps = Watts/Volts.
Jump the starter solenoid Take jumper wire from Battery + to trigger wire to starter (mounted on top of starter)
jump out the solenoid or relay. This will close the circuit for the high current.
A battery jump starter works by taking the charge from another battery, such as in another car, and passing it to the dead battery. When the charge is sufficient in starting the dead battery, it should then start charging itself as the engine runs.
NO You have to many AMPS from a car, you can jump start it butdon't charge it.
If the starter is bad no. Check battery, starter and solenoid to be sure which is bad.
Aplly battery voltage to it, it should jump, engage.
Jumper wire from coil + to battery+ Jump starter solenoid - Jump small trigger wire to starter connection
It isn't adviseable to use a battery charger to jump start a car unless the charger has a jump selection on it. Most newer models do have this function. The best thing to do, whether your charger has the jump function or not, is to take out the battery and put it on a trickle charge - usually about 2 amps, until the battery itself is fully charged.
