P12 Battery Chargers

P12 Battery Charger - 12V DC 40A

Discontinued - replaced by PN 7532

The P12 Battery Charger is a four stage, three output, dry mount charger designed for use in harsh environments where reliability, ease of use, and high performance are of primary importance. Backed by a 5-year warranty and technical phone support, the P12 Battery Charger is designed, assembled, and tested at Blue Sea Systems’ company headquarters in Bellingham, Washington.

Five Critical Features Extend Battery Life
  • User Defined Charge Profiles for setting voltages to match the battery manufacturer’s recommendations
  • User Defined Absorption Stage Values determine when the charger should exit Absorption Stage in order to prevent overcharging
  • Charge Coordination™ integrates with Blue Sea Systems’ Automatic Charging Relays to separate battery banks while the P12 is operational
  • PreFloat™ Stage prevents over charging by individually moving batteries out of Absorption Stage
  • Battery Temperature Compensation adjusts charging voltage up (for colder batteries) or down (for warmer batteries) as recommended by battery manufacturers for proper battery performance
