Overcharging is a possibility. It would also become warm from a long period of cranking, such as if you have trouble starting the engine. What exactly does hot mean? Rather warm or "oh, there's a problem here!"? Overcharging is the most likely possibility, and if it is boiling off its electrolyte (the water inside the battery) and needs frequent top-ups then overcharging is the most likely answer. It could also become hot if there is an internal short circuit.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
Dead cell in the battery. A light on anywhere on the vehicle. A relay that is stuck. Defective alternator.
No, a starter cannot cause a battery to fail to charge. It could cause the battery to discharge quickly.
Rusted connectors on a vehicle's battery could be the cause of a car that won't start. The process for cleaning these connectors can be detailed in full on wikiHow.
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.
Probably need a new alternator, or you battery cables or conectors could be bad If the battery is connected to your vehicle and it is not maintaining charge while the vehicle is running then it is more than likely your alternator that is out. If the battery does not have juice and is brand new then it is defective. I have also heard that if you place a car battery directly on concrete for a long period of time it will ruin. Always put a battery on a wood or a metal surface when storing.
The computer could have become confused. disconnect the battery from the vehicle. Leave it unhooked for several hours. Reconnect the battery. This should reset the computer, and hopefully solve the problem.
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
Yes they could be cleaned and battery charged
Yes it can...you may have a bad cell in the battery.. even with a bad cell the battery may have enough charge to start the vehicle but it then puts the alternator under a heavy load as it tries to charge the battery...Have them both tested.... There is also the possibility that the bearings in the alternator may be worn which could cause excessive heating....
If vehicle starts - probably a bad ignition switch If vehicle doesn't start could be a dead or low battery, loose or corroded battery cables
That's more likely to be caused by a low battery or corroded battery terminals but it COULD be the starter. If you can jump start it you probably have a faulty battery or alternator.
