It's the first fully automatic, constant-current battery charger designed to charge and/ or maintain up to 10 12-volt batteries simultaneously @ 2 amps.
 

• To avoid dangerous dead-short sparking, microchip circuitry will not activate output voltage until clips are correctly connected to battery.
• Simultaneously charges and/ or maintains up to 10 batteries.
• Maintains batteries at full charge.
• 2 amps per output charging current.
• Six foot lead with clamps included.
