Before you start

  • Sulfuric acid in lead-acid batteries can burn skin and clothing
  • Wear face shield and protective clothing when working with batteries
  • Ensure full charge to help prevent battery freezing
  • Ammeter reading should be very near zero if batteries properly charged
  • Keep batteries warm as temperature affects cranking power

Procedure

  1. Remove filler caps
  2. Maintain electrolyte level to FULL mark on battery
  3. If water addition necessary, use distilled water (or clean water low in minerals if distilled unavailable)
  4. Do not use artificially softened water
  5. Check electrolyte condition with 1U-7298 or 1U-7297 Coolant/Battery Tester
  6. Keep batteries clean
  7. Clean battery case with 0.1L baking soda + 1L clean water, OR 0.1L ammonia + 1L clean water
  8. Thoroughly rinse battery case with clean water
  9. Use fine grade sandpaper to clean terminals and cable clamps until bright/shiny
