A bad alternator will run down the battery.
Maybe. Lets check the simple stuff first.How do you know that it IS charging in the first place?
Get a voltmeter (VOM) and measure the voltage of the battery when the car is off. It should be more than 11.5 Volts. (Or it is really discharged battery).
The start the car and measure the voltage again. It sould be at least 13.5 Volts up to about 14.5 volts.
If not then the alternator is not giving enough voltage to charge.
If it is, then it could still be a diode in the alternator that is bad.
You cold have some accessory or light that stays ON somwhere draining the battery.
It could be a bad battery.
It could be a bad set of battery cables.
the first thing u should try is replacing the battery cables. my aunts car had the same prob. and replacing the battery cables fixed it.. if that's not it its most likely the distributor. that cost between $200 and $400 unless u go to a dealership where they will charge about $900 the first thing u should try is replacing the battery cables. my aunts car had the same prob. and replacing the battery cables fixed it.. if that's not it its most likely the distributor. that cost between $200 and $400 unless u go to a dealership where they will charge about $900
Do you mean charge by the vehicle running....or do you mean take a charge from a Bench charger? if its in the vehicle it could mean that either the battery/battery connection/cables, a faulty ground, or the alternator is defective. If its on a bench charger then the battery has a dead cell or is defective and needs replacing.
Most likely when the battery is no good anymore.
No, you can charge it on the mower and you do not have to remove it or disconnect the cables.
A battery booster is a portable battery, fitted with cables and a charger, which is used to charge a dead battery, especially in a car.
There are a couple of ways to charge a battery in a 2005 DeVille. You can use jumper cables with the use of another battery. You can also use a portable battery charger.
The laptops battery can only be charged by plugging the computer into the mains power. If it will not charge this way then the battery is dead and will need replacing.
Your question is not clear as to what you want to know, so I can only guess. You do not have to remove battery cables to charge the battery if that is what you are asking.
PT Cruiser batteries can be jumped with jumper cables. When jumper cables are attached to the battery in the PT Cruiser and are attached to the battery and another car battery, the battery will get charged, after a few minutes.
Changing your cell phone battery is a rare event, and you should look at a few critical points before changing your cell phone battery:Does it charge? A battery needs replacing if it does not charge.If it does charge, how long does it last? A battery needs replacing if the charge does not last as long as it should for your phone.Is the battery corroded or damaged in any way? A batter needs replacing if any part of the battery is corroded or damaged in any way, which could be potentially dangerous when using it.
Bad battery won't take charge Bad battery cables Fuseable link
You connect the cables BEFORE you plug in or turn on the charger. Positive (red) to battery positive first, then negative (black) to battery ground. Then you turn on your charger and set the timer.
If you are 100% sure the alternator is good, then either the wiring or the battery are bad. If the battery has a dead cell it will not hold a charge. Disconnect the battery cables and clean the connections. Charge the battery with a battery charger, and then connect the cables. If the battery is over 3 years old, it is more than likely bad.
Battery may have a dead cell and need replacing.
If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.
Connect a battery charger to the battery and let it fully charge. Do not charge it with the cars alternator. If it will not accept a charge the battery needs replacing. Connect positive (+) red cable to positive post and black negative (-) cable to negative post. Trickle charge the battery do not fast charge it as the charge won't take. Sure it will start the car a few times but a good charge to a battery is one that is done slowly
They don't. Jumper cables are used to charge a car battery. Hard drives have no use for such a device.
Something is on drawing power from the battery or the battery has a dead cell and needs replacing.
The battery has a dead cell and needs replacing or something is on pulling power from the battery.
You can get a new battery, you can jump start the car with jumper cables and another car with a charged battery. You can also put a battery charger on your battery to give it a charge.
Bad alternator? Bad voltage regulator? Bad Battery (won't take a charge)? Bad fusable link? Loose or corroded battery cables?
If you are 100% sure the battery and alternator are good and the battery is loosing it's charge then something is on pulling power from the battery. Can be any light or any relay on the vehicle.
To charge the battery on a Porsche Cayenne S you need to open the hood and on the driver's side open the tallest panel and put the cables on the two points.
