![]() NB: 0.01 change to Peukerts can make a reasonable change to calculated discharge. N = Exponentt1 = The hours of first discharge at amps A 1t2 = The hours of 2nd discharge at amps A 2Įxample: 8G4D 180A/HrDischarge 1 = 24 hours 7.8 AmpsDischarge 2 = 8 hours 20.7 Amps Recharge fully & discharge at 150% of expectedaverage load. Ie: A battery discharged for 20 hours to a terminalvoltage of 10.5v = Amp hours.Ĭ = A x T20 C = 5 x 20 = 100 Amp Hours.C = Battery capacity A = Amps discharge T20 = Time20 hoursPeukert’s Equation An x T = CĬ = is battery capacity at 20hrs dischargeA = is discharge current in AmpsT = is discharge time in hoursn = is related to battery construction & is relatively constant for any given battery with in a similar dischargetime.Įxponent “n” can be calculated for any given battery bank by comparing two discharge cycles.First fully charge battery bank from shore power/genset & discharge at 50% of expected average load (Notetime & amps) to 10.5volt terminal voltage (12v system). This is an exponent, which changes the discharge current to an effective discharge related to battery capacity.Most marine batteries are Capacity rated at the 20-hour rate. § Battery Capacity 220AH§ Charge Efficiency 85%§ High Volts Alarm 15.00V§ Low Amp Hours 100AH§ Low Volts Alarm 11.00V§ Peukert’s Exponent 1.25§ Reset capacity 5 ampsĪmp Hours display is battery capacity remaining The 600-DCM3.2 is factory preset with the following settings: To permanently mute an alarmPress the A button for 2 seconds, the displaywill show the mute symbol as shown, repeat toreactivate the alarm.

Press button CThis screen shows Capacity Remaining inAmp Hours. Press button AThis screen shows either chargingOR discharging Amps. To exit Bilge monitoring mode and resume batterymonitoring press “V” to return to supply battery volts. § In bilge monitor function press and hold “C” toreset the monitor back to zero. Press button V again (3RD position as volt monitor)The third screen shows the 3rd battery volts.Press button V again (3RD position as bilge monitor)The third screen shows the bilge monitoringinformation. Press button VThe second screen shows 2nd Battery volts. NOTE: If inputs 2 and/or 3 are not being used then low volts alarm needs to be brought down to zero, orinputs 2 and/or 3 can be looped into input 1.Īpply PowerPower-up screen will show for 5 secondsĪfter 5 secondsFirst screen shows the Supply Battery Volts.
