Checking Your Car Battery Yourself Matters More Than You Think

Your car battery is the power source for the starter system and various electrical components in your car. If the battery starts to fail, it can cause your car not to start, or lead to problems while driving.

Regularly checking your battery, especially before a long trip, helps reduce risk and gives you greater confidence when using your car.

How to Check Your Car Battery Yourself

1. Check the Battery's Age

The first thing to check is the battery's age.

• A battery less than 1 year old is less likely to have deteriorated
• If it's over 1 year old, you should check the battery's condition regularly
• If it's 2-3 years or older, watch for signs of deterioration and have it checked by a professional

Knowing the battery's installation date helps you plan a replacement before problems arise.

2. Check the Distilled Water Level (for Batteries That Require Refilling)

If your car uses a battery that requires distilled water, check the water level regularly.

• Refillable batteries should be checked every 1 month
• Semi-sealed (low-maintenance) batteries should be checked every 6-12 months, per manufacturer recommendation

Keeping the distilled water at the proper level helps extend the battery's service life.

3. Check the Battery's Indicator Eye

Many battery models have an "indicator eye" that shows the battery's status.

You can check the color of the indicator eye and compare it against the description on the battery's sticker to get a basic assessment of whether:

• The battery is still working normally
• It needs charging
• The battery should be replaced

While this method gives a basic check, it can't tell you the battery's health in as much detail as using a battery tester.

Checking Your Battery with a Tester Gives More Accurate Results

If you want an accurate reading of your battery's condition, we recommend bringing your car in to be checked with a battery tester at a service center.

The tester will display important readings, including:

Battery Voltage (Battery Test)

Check the Volts reading

• Should be greater than 12 volts
• If lower than this, it could signal that the battery is starting to fail or isn't holding enough charge

Cranking Voltage (Starter Test)

Check the Volts reading

• Should be greater than 10.30 volts
• If below standard, the car may be hard to start

Alternator Performance (Charging Test)

Check the Volts reading

• Should be greater than 13.30 volts
• If lower than normal, it could indicate a problem with the alternator or charging system

Checking all 3 readings will tell you whether the battery is still in good working condition or should be replaced.

When Should You Replace Your Car Battery?

If you notice any of the following symptoms, get your car checked right away:

• The car is hard to start
• Dim headlights
• The battery warning light is on
• You frequently need to jump-start the battery
• A tester confirms the battery has deteriorated
