Car Battery Seasonal Care
Keep your battery strong all year long
Winter: Extreme Cold Can Drain Power
Cold weather slows down chemical reactions inside your battery, making it harder to start your car.
- Test your battery before cold hits
- Keep terminals clean and tight
- Park in a garage when possible
- Consider upgrading to an AGM battery for improved cold-weather performance

Spring: Post-Winter Recovery
After winter, your battery may need attention from months of strain.
- Inspect for corrosion or damage
- Recharge if your car wasn’t driven often
- Check fluid levels if applicable
- Confirm proper charging with a voltage check

Summer: Heat Accelerates Wear
Hot temperatures can cause internal battery fluid to evaporate, shortening its life.
- Park in shade to reduce heat exposure
- Ensure battery is securely mounted
- Inspect for bloating or leakage
- Consider an AGM battery to handle higher temperatures

Fall: Prepare for What’s Ahead
Autumn is the best time to test your battery and get ready for winter demands.
- Schedule a battery test at your local auto shop
- Check charging system and alternator
- Look for signs of aging: slow starts, dim lights
- Replace old batteries before cold hits

Year-Round Maintenance
- Inspect and clean battery terminals every season
- Watch for slow starts or flickering lights
- Use a smart automatic battery charger if your vehicle sits unused for long periods
- Replace your battery every 3–5 years or as needed
