I have a portable car battery charger that is not plugged in and it is squealling to the top of its lungs. How do I make it stop before the neighbors scream at me?

My 2007 Hundai Sonata battery completely discharged. I recharged the battery with a trickle charger, but when I reconnect the terminals I haven't been able to stop the alarm or start the car.

Stick your key in the ignition and turn to start. That should stop the alarm. However, it sounds like your battery still isn't fully charged. Computer things go haywire when battery voltage is 9.6 volts or less.

Is the charger to be "on" while charging it; then on while hooked to battery?

The portable charger should NOTE be connected to a battery while the battery is connected to a vehicle! Charge the battery off the car, then disconnect the charger and put the battery into the vehicle to start it! If the charger is not working check the fuse! If that is ok then probably damaged the circuitry!

Hey Princess, ALL portable chargers have their own battery inside.. yours is 10+ years old.. its dead.. You will need to open the case and simply replace it..(the case will have screws/allen heads..(maybe security type).. remove them and ease the cases apart..If you are not comfortable or unable to do this... the battery shop MIGHT help you open it ,,(they want to sell batteries,,) they will be able to get you a replacement battery.. Good luck.

When i drive my car for about 20 miles it starts jumping.

If the car gets up to operating temperature and then lunges forward and cuts out and then lunges forward again, you should suspect a coil pack failure (coil module defective and not getting spark to one cylinder), a loose plug wire or bad plug wire or fouled spark plug.
