If you are not comfortable or knowledgeable with the electrical system of a car, have it checked by a mechanic. If the above solution isn't your problem, you can isolate what's drawing the current using this method. You need a multimeter capable of reading AMPS. Remove the ground battery cable and place the multimeter between the battery cable and the battery. Make sure you DON'T run your car like this!! With the car OFF, see how much current is being drawn from the battery. Some current draw is normal, as your cars computer and radio memory functions need power to retain their settings. Start by removing a single fuse and replacing it, each time checking the current on the multimeter. By process of elimination, if you pull the fuse on the circuit that's causing the trouble, the current draw will drop. There's your troubled circuit. Then you'd need a wiring diagram, which you can find on hmaservice.com, and trace down the short circuit.
1997 Hyundai Elantra Battery Size: L4/1.8 battery (12V)
battery size for 2005 Hyundai elentra
The Hyundai Elantra uses a lead type acid battery. Its battery life can last from three years to five years.
To reset the EMS on a Hyundai Elantra, disconnect the battery. Leave it disconnected for 10 minutes and then reconnect the cables.
Generally Elantra's take an international battery type. I'd try Sears or Advance or Autozone, some place like that.
Check the battery in the remote.
first of all do you have any dash lights coming on.(is there power from the battery)
The starter is located on the bottom left-hand side of the engine, near the front. You can follow the positive battery cable, from the battery to the starter.
Bad/shorted battery? (doesn't not hold a charge)
# Disconnect the negative battery cable # Remove the instrument panel center bezel # Remove the mounting screws and pull the radio out of the instrument panel # Disconnect the electrical connectors and the antenna lead and remove the radio from the car
you possibly have something draining the battery when the car is shut off, with the car shut off pull the positive cable off the battery and then just touch the cable to the positive post of the battery and see if you get a spark, if you get a spark you have something electrical draining the battery.
If your car alarm goes off on your Hyundai Elantra and the engine won't start, disconnect the battery. Leave it disconnected for several minutes.
