Intelligent Battery Charger-Analyzer for Small Battery Systems ( up to 10 A-hr )

( Replaces the Earlier BCA-1210 )

The  miniMasterCharger is an instrument designed to charge, trickle charge and analyze ( discharge ) Nickel-Cadmium, Sealed Lead-Acid and other types of rechargeable batteries.

With its multiple modes of operation:  Constant Current Charge ( dual and single rate ), Constant Current & Float Charge, Constant Current & Peak Stop Charge, Automatic Discharge ( analysis ), Resistance Discharge ( analysis ) and  Full Discharge ( deep cycle ).  The miniMasterCharger can satisfy the requirements of most small ( up to 10 A-hr ) rechargeable battery systems.

The instrument features safety interlocks to protect the operator, the charger and the battery in the event of reversed polarity connection, short circuit, open circuit ( no load ) and Over-voltage conditions.

Two large LED digital meters permit the simultaneous monitoring of voltage and current, while eight indicator lights display the status of the operation.

Other features include:

  • Storage ( nonvolatile ) of battery test profiles
  • Battery temperature monitoring
  • Microprocessor based timer with HH:MM and MM:SS timing selection
  • Interfacing to the BTAS-16 Computerized Battery Test System for monitoring, programming and control

Suggested Accessory:  we recommend the  VCM-100 to simplify the task of testing and calibrating the Charger-Analyzer.
