Discharge capacity tester for 6V & 12V batteries up to 80Ah

  1. General Details

    BAT/48524 is microprocessor device for capacity testing lead-acid 6V and 12V batteries with nominal capacity up to 800Ah (C10) or 1600Ah (C20). It is developed as a consequence of need for small, easy for use, safe, reliable and relatively cheep device for servicing and maintenance of starter, stationary and industrial batteries. BAT/48524 is high frequency dissipative discharger with fine regulation of testing current. It can be used for testing 20 hours capacity C-20 (I=Cn/20, 1.75V per cell) or for reserve capacity testing Rc (I=25A, 1.75V per cell). Discharging current is setting according to battery nominal capacity and test type. It measures, regulates and shows current, voltage, duration and discharged capacity in each second of test. LCD display shows the test flowing and results are stored in flash memory. With software for BAT/48524 it is possible to connect device with PC computer via RS232 serial port. Software gives opportunity of showing discharge graphs (testing) in real time, possibility of reading discharge data in case that device wasn’t connected with PC, printing and storing the results, creating reports etc.
