4. Coat the terminals with corrosion protection. Then, install the post cover.

5. For conventional batteries and batteries of low maintenance, follow these additional instructions:
   • Inspect the battery electrolyte level in each battery cell. A maintenance free battery does not require inspection.

   • Maintain the level of the distilled water to the bottom of the filler openings. If distilled water is not available, use clean drinking water.

   • A battery should not require more than 30 cc (1 ounce) of water per cell per week. This requirement should exist with the proper charging rate and with a moderate climate.

   • In extreme temperatures, check the water in the cells weekly. Cell water usage could be higher in extreme temperatures.
