Car batteries weaken in cold because chemical reactions slow down at lower temperatures-a 32F battery has about half the power of one at 80F. Winter starting draws extra current, which stresses an aging battery. Regular maintenance helps prevent dead batteries.

**Keep your battery healthy:**
- Have the battery tested annually before winter
- Ensure clean, tight cable connections
- Avoid leaving lights or electronics on when parked
- Drive regularly to keep the battery charged

**Signs of trouble:** Slow cranking, clicking sounds, or a battery light on your dashboard. Genesis of Downers Grove's Service team can test your battery, clean corrosion, and replace it if needed. If you're experiencing starting issues or want a pre-winter check-up, call (630) 598-9950 to book service.
