  • Calcium alloy is optimized to produce a fine grain, corrosion-resistant grid, maximize cycle life and minimizes water consumption for battery durability
  • Fully charged ACDelco Batteries (OCV is >12.5) should be stored in an upright position at temperatures between 32°F and 70°F. When a battery is stored, a very slow chemical reaction takes place between the plate materials and the electrolyte, causing a slow discharge. This reaction, called a self-discharge, occurs more rapidly at higher temperatures. Therefore, it is not recommended to store next to a furnace or other heat source. If an ACDelco Battery is completely discharged, the electrolyte will freeze when stored below 30°F. To prevent electrolyte freezing and battery damage, do not store ACDelco Batteries below 30°F if their OCV is less than 12.5 volts. Check battery every 2 months and maintain a voltage of 12.4 volts or higher
