Your battery may have a bad cell � have your local auto parts store �test� the battery for �load� � most do this for free; If you find the only one that wants to charge, go somewhere else. If it is not the battery then you have an overnight power drain. A light staying on, the radar detector plugged in, the DVD player plugged in, the Cell phone charger plugged in. Anyone can find the easy fixes, the hard ones are just that. These types of drains can normally only be found with an AMP meter and by going through every base circuit in the van to find what is drawing power and then determining what should not be drawing power. � To imagine the complication in this procedure, imagine you�re the water company, and someone has a leaking faucet, and you need to know who it is. So, you turn off everyone�s water and then turn them back on, one at a time until you find the one pipe that shows someone using water. Then you follow that pipe to the block it supplies, then go door to door � ETC � This is best left to someone who knows car electrical systems. A 1998 AWD ASTRO - My battery was sometimes dead. Dealer reported finding no problems. By chance, I discovered excess grease in passenger window lift track penetrated and shorts the electronic window lift motor - A warm day, at night grease gells by morning the battery would be dead.
Either the battery has a dead cell, which will require you to replace it, or something is on pulling power from the battery. Disconnect the negative cable and leave it off overnight. If the battery is dead the next morning the battery is defective. If not, then find out what is pulling power from the battery. Ignition switch may be defective.
Check your battery, it can be weak or dead. If the battery seems fine, your alternator may be weak or needs replaced.
Dead cell in battery or something is on pulling power from the battery. Disconnect the negative battery cable overnight with the battery fully charged (12.6 volts). If the battery is dead the next morning it has a dead cell and needs replacing. If however the battery is still fully charged then a light is on somewhere or a relay is stuck closed.
I have a 3 year old who was always turning on the back reading lights. Then the next morning I would come out to a dead battery. I just removed the bulbs for a short term fix and will replace them when she gets older.
Poor cable connection at your battery , or dead battery - anybody else have any suggestions (Helpfull)
I would say a dead battery.
Your battery might be dead or very close to dead. If the interior lights come on but go dim when you try to start then the battery is probably dead. Otherwise, get a new starter.
could be a dead cell in battery if battery ic over 4 yeare old is probably battery
Something is causing a drain on the battery even with the vehicle off and nothing turned on. A good mechanic can do a drain test on the battery to see what may be draining the charge. A dead cell in the battery itself will also cause the battery to go dead. Disconnect the negative battery cable overnight and if the battery is dead the next morning it has a dead cell and must be replaced. If not look for a light that is on or a relay that is stuck.
Either your battery is dead, or your alternator has failed.
<improved answer>Just to correct the old answer, if the CMOS battery is dead, then the computer will not turn on in order for you to reenter it the next morning. It means that the CMOS battery is getting weak, and yeah, you could replace it. <old answer>It is most likely that the CMOS battery is dead. Replace it.
Either the battery has a dead cell, which will normally drain it overnight, or something is on pulling power from the battery. If the battery has a dead cell it will have to be replaced. The easiest way to determine this is to fully charge the battery and then disconnect the negative cable overnight. If the battery is dead in the morning it has a dead cell. You may not even be able to charge it with a dead cell. If the battery is still fully charged the next morning then you have another problem. Check all the lights on the vehicle. Under hood, trunk, dome, curtorsey, glove box, etc. One of them may be staying on. Also check your brake lights. If you find no lights are on then you may have a relay that is sticking. Can be power windows, locks, seat, etc.
