What can cause battery to drain on a 1996 trans sport se?

A dead cell in the battery will cause the battery to loose it's charge overnight. The battery must be replaced if this is the case. Also, any light that is on will drain the battery. A stuck relay will also drain it. Disconnect the negative cable at night in the dark and if you see a spark of any size then something is on. You will see a very tiny spark which is normal but look for a spark that show a large power draw.

What could cause a 1994 Buick park avenue battery to drain overnight?

Most likely there is something that is draining it. In case it might be the battery itself, disconnect the battery terminals at night. When you reconnect in the morning and the battery is OK, then the problem is in the electrical system somewhere. If the battery is dead then the battery needs to be replaced. Finding the fault in the electrical system can be difficult. Check to make sure all lights go out when the car is turned off. Pulling fuses to see if any stops the drain could help isolate the problem too. Good luck

Does battery corrosion in the middle of the battery under the tie down strap but not on the terminals cause battery power to be drained?

No, corrosion will not cause a battery to drain, even if the corrosion is on the terminals. Several factors can cause battery drain, I would first have the battery tested to see if the battery it self is not bad. If the battery is good, then the most common is a short. All most all new cars have a certain amount of drain,(measured in milivolts) this drain is for clocks and computer memory's, and it would take several days of a vehicle sitting for the battery to be drained. Don't immediately assume you have a problem if you see 2-6 milivolts of drain on a battery with the key out, now if your battery is being drained after being parked over night, you have a problem. The easiest way to pin down the problem short is to disconnect your positive battery cable from the battery, take a 12 volt test light and clamp one end to the positive cable, and hold the probe to the positive post. Now if you have a short the light will come on. Have someone help you by pulling the fuses one at a time. If when a fuse is pulled the light goes out you have isolated the short to that system. If you pulled all the fuses and the light never went out try disconnecting all the wires from the alternator, 9 times outta 10 do this will let you know where your short is. If the system is not critical like power locks some people just leave the fuse out.

Can a bad starter start the car but still drain the battery over night?

Not likely. The starter would have to stay engaged to drain the battery and that you would hear loud and clear. Check for any light that is on. Dome, glove box, trunk, back-up, under hood, etc. It can also be a stuck relay. Lastly it can be a dead cell in the battery which would require the battery be replaced. If the battery is over 3 years old or has been run down a couple of times it is more than likely your problem.

Unplug Your Computer At Night?

When you leave your computer plugged in at night, it drains power even after the battery is full. This is true for the best laptop computers 2010 has to offer or any of the more recent models.
