Consider Refurbished or Remanufactured Batteries (With Caution)

Sometimes, you can find refurbished batteries at a lower cost. These can be a good option for older vehicles where you don’t want to invest heavily. However, they typically come with a much shorter warranty and might not last as long as a new battery. Use caution and ensure you understand the warranty terms.

Utilize Free Installation Offers

As mentioned, many auto parts stores offer free installation with the purchase of a new battery. This is a no-brainer if you’re buying a battery from them and your car’s battery is easily accessible.

Proper Maintenance is Key

• Keep Terminals Clean: Regularly check your battery terminals for corrosion (a white or bluish powdery substance). Clean them with a wire brush and a mixture of baking soda and water. Apply a terminal protector spray afterward.
• Check Water Levels (for non-sealed batteries): Some traditional lead-acid batteries have removable caps allowing you to check and top off electrolyte levels with distilled water. *Never use tap water.*
• Regular Driving: Short trips don’t allow your alternator enough time to fully recharge the battery. If you mostly make short trips, consider a longer drive every week or so, or use a trickle charger.
• Avoid Draining: Don’t leave lights on, the radio playing, or accessories plugged in when the engine is off.
• Test Regularly: Have your battery tested periodically, especially as it approaches its typical lifespan (3-5 years). Many auto parts stores offer free battery testing. This can give you an early warning before it completely fails.
• Insulate in Extreme Temperatures: In very cold climates, a battery blanket can help maintain battery temperature, improving starting power. In very hot climates, ensuring your battery is securely mounted and has good ventilation can help.

Use a Battery Tender/Trickle Charger

If you store your car for extended periods, or if you only drive it occasionally, a battery tender or trickle charger can keep your battery fully charged and prolong its life. These devices provide a slow, steady charge to prevent self-discharge.
