Auto Electrical Tips

  • Have your battery tested before every winter—cold weather dramatically reduces battery capacity
  • Keep battery terminal connections clean and tight using a wire brush and anti-corrosion spray
  • If your vehicle sits for extended periods, use a battery tender to maintain the charge
  • Never attempt to jump-start a cracked or leaking battery—it could explode
  • Replace your battery every 4 to 5 years as preventative maintenance
  • If you notice a burning electrical smell, disconnect the battery and get a professional diagnosis immediately
