Interstate Batteries recommends you take special precautions with your truck battery this winter:
1. Have the vehicle's starting and charging system tested every three months or every oil change.
2. Use a battery charger to maintain charge levels and keep the battery in good condition. If the battery is more than three years old, have it tested more frequently to ensure it can survive the coldest winter months and/or replace it as a preventative measure.
3. Have the battery tested before taking a long trip.
4. Inspect the battery cables, posts and fasteners. Make sure the cables are in good shape and are secured firmly to the battery. Cable corrosion reduces power from flowing freely from the battery, reducing the power available to start the truck.
5. Clean the battery terminals with a wire brush or battery cleaner spray.
6. Choose the appropriate battery for the vehicle. It should be the correct size and ratings, especially for a vehicle that experiences extremely harsh winter conditions.
7. When possible, keep the vehicle in a garage overnight or plugged in, especially in areas with extremely harsh winter conditions. If garage storage is not possible, invest in a battery heater.
8. Avoid damage to the battery and keep connections tight.
9. If the battery is not a sealed model, check the fluid levels, using distilled water to fill any cells that appear low.
When working with or around a battery, always wear protective eyewear, remove all jewelry and wear long sleeves to protect skin from an explosion of battery acid.
