Installation- Step 4: Install the New Car Battery
- Read and follow the Safety and Handling Information on this website.
- Clean the tray where the battery rests. Use steel wool or a wire brush to rub the metal clamps and remove any corrosion.
- Place your new battery in the battery tray (make sure your battery is fully charged). Make sure it faces the proper direction so that the positive and negative terminals line up with their corresponding cables. Secure the hold-down strap in its original position over the new battery, ensuring it is properly secure to prevent movement or vibration wear. Do not tighten the hold-down bracket too hard, since this can damage the plastic case and cover.
- Attach both cables. Attach the positive (red) cable first, following with the negative (black) cable.
- Hand-tighten the nuts. Do not over tighten the terminal bolts; the following values are recommended:
- SAE (tapered) automotive terminal: 50 to 70 inch-lb.
- Side terminal (3/89 nut): 70 to 90 inch-lb.
- Threaded stud terminal: 120 to 180 inch-lb.

Car and Truck Battery Installation Tips
- Check mounting surface for objects or protrusions that could cause damage or wear to the case or cover. The battery must be level in the tray. Make sure there are no foreign objects in the tray that could damage the battery.
- Replace cables and connectors that show signs of corrosion, rust or other damage.
- Do not lift or handle the battery by its terminals.
- If using a dual-terminal battery (it has both top and side terminals), use top terminals for accessory hookups and vehicle starting. Only use battery side terminals for vehicle starting.
- Check for proper battery polarity with respect to vehicle specifications. “Ground” polarity is typically indicated. “Reversed” polarity can cause serious damage to your vehicle’s electrical system.
- The hold-down should be tightened so that it is snug.
- Top bar or top frame hold-down: 30 to 50 inch-lb.
- Bottom recess hold-down: 60 to 80 inch-lb.
- Bottom ledge-type hold-down: 70 to 90 inch-lb.
Caution: Some vehicles equipped with advanced electrical systems may require special handling procedures. Please refer to your owner’s manual for details.
