Why is my battery going dead after setting for two days?

If there is no obvious indication of lights remaining on after shutting the truck off then having the battery checked at your friendly auto parts store may be in order. Even a new battery can fail. Check the terminals especially if the engine has a poor crank. The voltage should not go below nine during crank at the battery. If the voltage is above 11 and the motor will not crank look for a bad connection.

If the truck is running no lights or heater off the voltage should above 13.

Monitor the voltage for a day or two and see if the voltage drops. Much below 11.5 would indicate that the battery is discharging. With out special equipment it is hard to see the drain from the battery by the truck.. The Electronic modules are always drawing some low level current from the battery.

I have a 03 Saturn vue with a 3.0,wife was driving it on Friday was running fine, she came home for 20 then was going to the store car started to run rough then died, now it won't start. And has a poor...

check all battery connections are good and clean and tight if they are and that is not the problem. Try jumping battery with cables if it starts it will usually be a bad battery or alternator or starter moter,.check voltage at battery should be 13 volts or better. If less charge battery load test battery or take it to auto parts store and have it load tested. if battery is good check voltage with car running it should be between 13.5 and 15 if lower or higher voltage check belt on alternator (if lower voltage). If voltage is high or low and belt is ok remove alternator and have tested at any parts store .It is usually free. If none of these items check bad Remove starter motor and have it tested . again free at most auto parts stores.n If this was helpful please leave good feed back

Key fob not working but when battery died is naking noises

It's quite likely the noises (clicking) you are hearing are electric mechanical relays struggling to activate. Bottom line is the battery is practically depleted of electricity. Connect a trickle charger to the battery, switch it to automatic charge and try starting the car after the voltage gauge displays a voltage measurement of 12 volts (which would require several hours), you may at least be able to drive it to a service center to avoid a towing cost, check your automobile insurance policy to see if you have towing reimbursement coverage. Call several service centers for price quotes while the battery is charging. Quite likely your electrical alternator (a mechanical part that charges the battery while the engine is operating) has failed and you have used the remaining electricity contained within your battery. If you or a family member/friend is mechanically inclined, many auto parts stores will test your alternator and battery free of charge. Batteries don't last forever, they can only recharge as long as their cells are healthy, so it's possible you also MAY require a new battery however it seems that your alternator may be the culprit here. Expect at 150-300 repair cost including a replacement alternator for professional mechanical service, plus the cost of a battery if required.

Low voltage

Clean all connections and make sure they are sound on both the battery and alternator. Electricity does not like to flow properly through dirty and poor connections.

If your alternator is not pushing charge at over +13V(sometimes over 14V, all depends) when the engine is running, then it is faulty. Take it back to where you bought it from and exchange for another.

If the alternator is fine whilst running and the battery shows 9V when the engine is stopped, then your battery is not holding the charge and is faulty. Take it back, same as if the alternator were faulty.

By rights, all things being equal, once started, your engine should run without the battery being connected at all, if your alternator is operating correctly. Your battery is only a storage device to initiate engine ignition. They are rated by CCA, which is simply crank power to turn the engine over and start.

Code p0562 on a 2004 Kia Spectra

Hi there:

P0562 KIA - System Voltage Low
The battery supplies electricity to the ECM even when the ignition switch is OFF. This electricity allows the ECM to store data such as DTC history, freeze frame data, fuel trim values and other data. If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The next time the engine starts, the ECM will turn on the MIL and a DTC will be set.

Possible causes:

- Loose or missing alternator drive belt
- Faulty alternator
- Battery defective
- Open or short system voltage circuit

Tech notes:
Start by recharging or replacing the battery.

The P0562 code is detected when the battery voltage detected by the ECM is less than a calibrated value

- Engine Light ON (or Service Engine Soon Warning Light)
- Slow engine start
- Low battery power

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

When i drive my 1993 oldsmobile 98 my voltage will start at or around 12.4 but when i start driving it drops to 11.7 and then slowly drops from there never going back up. i bought a new battery but the...

It is almost definitely a bad alternator, but could also be a limited number of other things. A bad battery terminal could cause this problem as well or other loose or corroded connections. As for your 12 volt reading on the alternator, I should explain a little about electricity. If electricity travelled down a highway, the number of lanes would be the voltage and the speed limit would be the amperage and the wattage would be lanes multiplied by the speed limit. 12 lanes travelling at 2 miles per hour aren't getting anywhere fast. Also, a car battery's charge voltage slightly above its' output voltage, so it should be roughly 13.4 volts up to about 15 volts.

Low voltage at starter when ignition switch is turned

Make sure the battery is fully loaded, check voltage when the key is turned to START. If voltage drops below 10vdc, jump start vehicle and have starting/charging system at AutoZone or similar auto parts store. If voltage at the battery is good, check wiring from battery to starter solenoid, make sure terminals are free of rust and corrosion and tight, wiggle the wires to make sure no loose connections exist. You should get the same voltage at the starter solenoid as you did at the battery terminal, if not replace cable. If you get same voltage at the starter solenoid, the solenoid itself or the starter may be worn/defective. There is a starter rebuild kit available at auto parts stores for a fraction of the price of a new starter.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Car wont stat...battery voltage good and also good connections...will start after a chage or jump start but will not crank back up when turned off...starter solenoid clicks

If you have to jump it or charge it in order to get it started every time, I think maybe the battery is no good. Take the battery to a good auto parts store and they will test the battery free of charge. Your gages can show good battery voltage and still not have enoughcranking amps to start the engine.

1997 eclipse has to be charged every day in order to drive

There seems to be a no charge state in this case. I recommend checking the charging system. use the procedure below to isolate this issue.

Wear protective eye wear and clothing and remove all jewelry when checking your battery and charging system. Jewelry is a good conductor of electricity and is not recommended. Most batteries wear out every 3 to 5 years and need to be replaced. Always replace your battery with an equal replacement battery to assure proper operation. Automotive batteries have a +positive terminal (red), - negative terminal (black). Electricity is stored in the battery and then supplied to the vehicle when the engine is not running. While the engine is running the vehicles alternator charges the battery for future use. (Note: never disconnect the battery while the engine is running. If the battery cable is disconnected from the battery a spark can be generated which can cause the battery to explode or a major electrical malfunction to occur.)

To check a battery surface voltage, remove the positive terminal protective cover. Connect the +positive side meter lead (red) to the positive side battery terminal. Connect the - negative (black) side meter lead to the negative battery terminal. With the vehicle not running and the car sitting over night the battery voltage should be between 12.5 and 12.8 volts.(You will need to use a voltmeter for this testing procedure)

The alternator is rotated by a drive belt driven by the vehicles engine while it is running. Electrical voltage and amperage are generated to recharge the battery and supply voltage to the electrical system of the car. The alternator is held in place with mounting bolts. There is a main electrical wire on the rear of the alternator that supplies voltage to a main voltage junction box. If your alternator is not charging properly, your battery will slowly drain down from operating all the electrical systems in your car and stop the car from running.(most non charge states will be the cause of a loose belt or a low tension rate, due to a mis-adjusted alternator. make sure you have enough tension in the belt for full rotation of the alt pulley)

Next, you will need to check the alternators output with the Amp meter.

Testing the amperage output of the alternator is good for measuring the amount (not the level) of voltage the alternator can produce. This test can be tricky because if the alternator is weak it can still show it as producing amperage. Which is good, but if the voltage is low, it will still allow the battery to go dead. To check the amperage output of an alternator an amp meter is needed. Once the meter is connected start the engine. Next turn on all electrical accessories and raise the engine idle to about 1200 RPM. The alternator should output the max amperage it was designed to produce. Example: a 90 amp alternator should output about 88 amps. Note: An alternator cannot sustain maximum output for long periods of time. If the alternator is forced to operate at maximum output it will overheat and fail. An alternator is designed to operate at max amperage output only for a reasonable amount of time.

((Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts. If not the alternator may need replacing.)))
