REMOVAL & INSTALLATION




CAUTION
When working on the battery, be careful at all times to keep metal wrenches from connecting across the battery terminal posts. DO NOT wear any type of metal jewelry, this includes watches!

  1. Use a wrench to loosen the through-bolt for the terminal. If necessary, use a prybar to carefully spread the terminal halves apart. Disconnect the negative terminal. Then, repeat the process to disconnect the positive terminal.
  2.  
  3. Remove the retainer screw from the retaining block located behind the battery. Remove the retainer.
  4.  
  5. Carefully lift the battery out of the engine compartment using a battery lifting strap or equivalent.
  6.  
  7. Thoroughly clean the entire battery box area. Use a mild solution of baking soda and water to cut through the corrosion. This is done because the battery retains its charge better in a clean environment.
  8.  
  9. Replace the battery with one having an equal or higher rating in amp/hours. Note that the older a vehicle is, the more likely it is to benefit from an increase in battery capacity due to increased resistance in the wiring.
  10.  
  11. Replace the battery in exact reverse order, making sure it is securely mounted before starting to connect the wiring. Make sure the battery terminals are clean, using a special brush designed for that purpose, if necessary.
  12.  
  13. Connect the positive terminal first, and then the negative, tightening them securely. Coat the terminals with petroleum jelly to protect them from corrosion.
