Material Safety Data Sheet (PDF)


  1. The vehicle must have a properly working alternator, and should not have “aftermarket accessories” with amperage drain exceeding 10 amps.
  2. The vehicle must have a fully functional voltage regulated charging system. Use of accessories that prevent the charging system form maintaining the battery in a fully charged state will void the warranty and cause premature failure. For these applications, an Optima deep cycle battery is recommended for this combination of starting and heavy cycling.
  3. Red top batteries should only be used for hot rod / street rod / O/E applications where the system has a fully functional voltage regulated charging system. Red top batteries should not be used for off road/circle track aftermarket performance applications. The warranty is voided when a red top battery is used with out a fully functional voltage regulated charging system.
