If your vehicle has a battery marked with LOWER and UPPER on its side, you can check the electrolyte level, which should ideally between the LOWER and UPPER mark. Other most common signs of a dying car battery include:

- Jumping your battery every 3-5 days or even more frequently
- Battery death within 15-30 minutes of idling with the engine off while other accessories are running
During Startup
- Three or more turns for ignition
- Dimming lights and/or accessories prior to startup
- Greater difficulty in startup after idling for long hours, especially in the cold
During Driving
- Slightly rough stops for traffic
- Intermittent shutdowns of the radio and/or other accessories
- Dimming lights and/or accessories when the accelerator is pressed
