What else can I help you with?
My car died while driving last night so i replaced the battery. AutoZone tested the alternator and said it was working but it was draining my battery slightly...what could be causing this?
Don't believe a word AutoZone tells you. My battery died so I went there and they tested my battery and alternator and told me it was the battery. So I bought a new battery and 2 days later, dead again. Went back and they tested again and THIS time, it was the alternator. I went nuts on them and ended up getting both my battery AND alternator for free for their mistake that left me stranded at 12am.
Should a 4 year old car battery die?
They normally last longer than that.... assuming your alternator is working correctly, and that you're using it as intended and not as, say, a marine battery, which will dramatically shorten its life.
You have a 92 lumina van 31L it wont start or has any power you have bought a new battery weeks ago and it was fine last night it sounded as if it wanted to crank now it doesn't even make a sound what?
Batteries are just electrical storage devices. They only store what is generated elsewhere, in the case of your vehicle, the electricity is generated in the alternator. If you alternator has failed your battery will not be able to store anything. If the alternator is working but an electric component, such as a light, is left on it can use up all of the stored electricity and there will be nothing left with which to start the engine. Never replace a battery without first verifying that the alternator is working. There might be nothing wrong with the old battery and you'll have to get an alternator later anyway.
What does it mean when you have a low charge battery on a 2001 vw beetle?
A low battery charge is a sign of failing battery or charging system. most batteries last 4-5 years then need replacement. If your battery will not hold a charge have your alternator checked. most auto part stores will test your alternator for free.
Volvo 1991 240 automatic that runs for while then the battery dies Reading 12v off the alternator wires while running Last time it died radio went on and off?
Your alternator is not charging. When a vehicle with a 12 volt system is running, the alternator normally puts out at least 13.5 to 14.5 volts More than that, the battery is overcharged. Under that, the alternator is not functioning and it is running only off the battery voltage.
When an alternator goes bad does it ruin the battery?
YES. it will ruin your battery as the battery needs the alternator too recharge a full battery will last you 30-40 min maybe more or less depends.. it will drain your battery and make you stall (you mite be able too recharge later)maybe) if your alternator is bad YOU must get a new or used one ,its recommended if you get a new alt. get a new bat. as this will supply you years of trouble free from your car electrical issues.
Can you Help as im not sure why but the two different batterys ive used have both gone flat whilst driving my peugeot 206 gti?
If a new battery goes flat the most common fault would be a fualty alternator or regulator on the alternator. The alternator is belt driven by your engine and generates electricity to re-charge your battery. A brand new battery may last a few days but without re-charge from the alternator it will eventually go flat.
1996 dodge neon won't start full of gas oil water and all vital fluids fuel pump hums indicating it's working check of timing belt ok yet car will barely turn over as if the battery is weak any ideas?
Maybe the battery is weak. Possibly the starter has failed, the alternator has stopped recharging the battery or the battery may just be worn out. Batteries typically don't last more than 5 or 6 years. If you have a volt meter, test the battery voltage, first with the engine off. It should be a full 12 volts and possibly a little over. If the battery voltage is down you either need a new alternator or battery. Jump start the vehicle and test the voltage while YOUR engine is running/disconnected from the other car. If you have 13.5 volts (approximately) the alternator is ok. If it's below 12 volts with the engine running, the alternator is toast. At that point, if you haven't figured out anything, take the vehicle to an auto parts retailer to have them test the charging system. Remember that when working properly a battery is only a storage device for electrical energy. If the alternator doesn't recharge the battery, the battery will have nothing to store.
89 prelude shut off while driving but started after jumped but didnt keep running for long?
Check your alternator (it charges the battery) If it quits you are running straight off the battery and that won't last long. Also check your belts. If they are loose and slipping your battery won't get carged and your alternator won't work properly
How long is a car battery supposed to last?
Car batteries should last for a few years at least. There are factors that affect battery life such as alternator, humidity/salinity and quality of battery. Also using a battery with the proper amount of cold cranking amps is important as well. Check with your local retailer to find the best battery for your vehicle.
Why does your ipod touch battery last only 2 hrs?
You are either using it a lot, or the battery is not working properly, and you need a replacement.
Would a bad alternator cause the truck to stop running?
Yes, the alternator provides electrical energy to keep the battery charged. If the alternator isn't functioning, the battery will discharge and there will be insufficient electrical energy to operate the ignition and other electrical components. Understand that a battery is only an electrical STORAGE device. Electrical energy is produced by the alternator. The function of the battery is to provide electrical energy for NEXT time you want to start the engine. Once the engine is started, the alternator must take care of all electrical requirements of the vehicle as well as for providing enough additional electrical energy to replace electrical energy to the battery that was last used when the engine was started.
