How to Check Your Car Battery
Now that we’ve covered the signs of a dead battery, let’s move on to the steps you can take to check your car battery. Here’s a comprehensive guide:
Step 1: Locate Your Car Battery
The first step is to locate your car battery. This is usually found in the engine compartment, but it may vary depending on the make and model of your car. Consult your car’s manual or look for a label on the battery to confirm its location.

Check the battery’s age by looking for the manufacture date code on the side of the battery. Most batteries have a date code that indicates the month and year of manufacture. If your battery is more than three years old, it may be nearing the end of its lifespan.
Step 5: Check the Battery Water Level (for flooded batteries)
If you have a flooded battery, check the water level by looking for the fill cap. Make sure the water level is at the recommended level, and top it off if necessary.
Step 6: Check the Battery for Swelling or Leaks
Finally, inspect the battery for any signs of swelling or leaks. If you notice any swelling or leaks, it’s likely that the battery is damaged and needs to be replaced.
