Car Battery Maintenance Guide
Keep your battery running longer with these simple tips.
Why Maintenance Matters
- Extend battery life
- Prevent unexpected breakdowns
- Improve performance in all weather conditions
Keep It Clean
- Inspect the battery case for dirt or corrosion
- Clean terminals using a battery brush and baking soda solution
- Ensure all connections are tight
Corrosion and loose connections can reduce performance and cause starting issues.
Check the Connections
- Frayed or cracked wires
- Loose cable clamps
- Damaged or corroded terminals
Always turn off your engine and wear gloves and eye protection before inspecting or cleaning the battery.
Watch for Signs of Trouble
- Engine is slow to start
- Headlights dim when idling
- Clicking sound when turning the key
- Dashboard warning light is on
Test Regularly
- Every 6 months, or before extreme weather seasons
- Use a multimeter for at-home voltage checks
- Get a professional load test at a service center
- Healthy battery voltage: 12.6 volts when fully charged (engine off)
Handle with Care
- Avoid open flames and sparks
- Store batteries upright in a cool, dry place
- Recycle responsibly — never dispose of batteries in the trash
Pro Tip
Cold weather can drain batteries faster. Get your battery tested in fall and spring to stay ahead of seasonal changes.
When to Replace
- It’s more than 3–5 years old
- You’ve had multiple jump-starts
- It fails a voltage or load test
