Off-Season Battery Maintenance

Prior to off season storage, clean batteries of dirt, saltwater residue and corrosion build up.  Yamalube Battery Cleaner & Protector is a great neutralizer for the white battery acid corrosion residue on the terminals and cables, plus it leaves a protective coating on the terminals when you're done.  In a pinch you can also use baking soda and water.  Wire brush the cable ends and replace any ring terminals that appear to have some wear.  Check the electrolyte levels in all cells; it should be to the bottom of the ring in the case.  Distilled water or water that has been de-mineralized should be used to refill batteries; do not refill with battery acid or tap water.

After cleaning, fully charge the battery.  A battery that is stored with a low charge will have a dramatically shortened life span due to sulfation of the battery's lead plates.  Lead plates start to sulfate when the specific gravity of the electrolyte (sulfuric acid) falls below 1.225 or battery voltage measures less than 12.4 volts for a typical 12V lead acid battery.
