Why does auto battery leak after charging?

An auto battery could be leaking for a couple of reasons. The alternator could be overcharging the battery causing the leakage. Or the battery itself could have a short or other internal problem causing it to leak when charging.


What could be the problem if gauges go down and car dies and won't start unless jumped?

Sounds like your charging system isn't working and you are running off battery power until the battery goes dead. Have the battery and the charging system tested to determine what part is at fault.

Bad battery or bad battery connection. The click is the starter trying to engage, but lacking the power to turn the motor.


Why is your dodge stratus not charging a new alternator?

Cars don't charge alternators; alternators charge cars. If your new alternator isn't charging, it could be your battery is bad or your battery connections are corroded. Another thing it might be is your voltage regulator. Many alternators come with built-in voltage regulators, but if your system has a standalone v.r., it could be bad too. Finally, if your 'new' alternator is actually a refurbished or rebuilt one, it could be a bad rebuild. It happens.


Flashing battery symbol while driving?

Could be that the alternator is not charging the battery properly Check with a voltmeter A fully charged battery should read around 12.8 without engine running With engine running voltage should read around 13.8-14.2 The most likely cause is a broken alternator drive belt

Do you have to disconnect a battery charger from the battery or can you just unplug it?

Best to unplug it and then disconnect it from the battery. Reason being is that if you disconnect it from the battery first you will create a spark. That spark could ignite any fumes from the battery.

Why wont your battery hold a charge?

Could be the life of the battery has expired or the charging system is faulty or the vehicle has a draw on the system killing the battery when not running. Drive the vehicle to your local auto parts store. They will test the battery and the charging system at no cost. Battery is bad or something is draining it. Most places that sell batteries can check it. With it charged, disconnect it and see if it holds a charge. If it does, something in the car is draining it. Dead cell in the battery or something is on drawing power from the battery.

What is wrong when battery light comes on in 1996 Toyota Corolla?

It means the battery is not being charged or is being overcarged. Could be the drive belt loose, the battery getting old/having distorted plates. Could be the alternator not producing enough voltage/charging current, or, rarely, too much. Local tyre & battery centre can do a discharge test on the battery. A meter across the battery will show if battery charging properly. Make sure all the cable connections between the body, battery and engine are clean and secure.


Does more current flow out of a battery than into it?

If you are recharging a battery you will need to input more power than you could draw from the battery after charging, as the charging process is not 100% efficient. Most of this excess power will be lost as heat during charging.


Why does your battery warning light stay on despite the battery being charged normally?

Sometimes even though the voltage at charging is good the battery or alternator could be low on charge or charging low for your vehicles specs.

Could a bad coil keep the alternator from charging the battery?

Yes, because a bad coil will not allow the engine to run. But if the engine is running then the coil has nothing to do with the alternator charging the battery.
