Your Hyundai uses a combustion engine, and for that reason to start and run, it needs a mix of enough fuel and air. If your Hyundai issues are part of a faulty fuel system, this might be a clogged fuel filter or a failing fuel pump relay, which could mean the engine may not be receiving the fuel it requires to get the vehicle going.

If you think it's possible a battery problem is the culprit as to why your Hyundai has difficulty starting up, then the first thing you should do is examine the battery and check the battery terminals. You want them to be clean, not corroded and tightly connected. If you find that the terminals are in fact corroded you can try cleaning them with a mix of baking soda and water. If the battery is just old or weak, you will have to replace it, otherwise, even if you charge it up enough to start the car, it will likely die again in the near future. You can make use of a multimeter as a way to test the life of the battery to see if it’s worth saving or if it needs to be replaced.

If you can get the vehicle to start up temporarily (you may need to jump start the car for that), but when it’s going, let the car run, and while its running, disconnect the positive terminal of the battery. It's likely because of a problem with the alternator if you notice that your Hyundai dies immediately when you disconnect the positive terminal. However, be warned this test can be dangerous if you don't know what you're doing, and may damage the delicate electronic components in your vehicle, so its best to consult with a professional mechanic locally or online, before ever attempting this.
