Peukert’s Discharge Rates Calculation
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. Ie: A battery discharged for 20 hours to a terminal
voltage of 10.5v = Amp hours.
C = A x T20 C = 5 x 20 = 100 Amp Hours.
C = Battery capacity A = Amps discharge T20 = Time20 hours
Peukert’s Equation An x T = C
C = is battery capacity at 20hrs discharge
A = is discharge current in Amps
T = is discharge time in hours
n = is related to battery construction & is relatively constant for any given battery with in a similar discharge
time.
Exponent “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 (Note
time & amps) to 10.5volt terminal voltage (12v system). Recharge fully & discharge at 150% of expected
average load. Use the following equation.
n = Exponent
t1 = The hours of first discharge at amps A 1
t2 = The hours of 2nd discharge at amps A 2
Example: 8G4D 180A/Hr
Discharge 1 = 24 hours @ 7.8 Amps
Discharge 2 = 8 hours @ 20.7 Amps
Program this exponent in toPeukerts.
Log t2 - Log t1
Log A1 - Log A2 Log 8 - Log 24 Log 7.8 - Log 20.7 0.9 – 1.38 0.89 – 1.32 0.48 0.43 = 1.1
n =
Log t2 - Log t1
Log A1 - Log A2
n =

NB: 0.01 change toPeukerts can make a reasonable change to calculated discharge. Alter in small steps.
For example, 100 Amps for 1 hour = 100Amp hours. Using Peukert’s exponent of 1.25,An x T, 1001.25*1=316
Amp hours. A 25% exponent change makes 316% change.
Calculating exponent “n” from discharge cycles is the only way to achieve an accurate discharge exponent.
This meter comes with a factory set exponent of 1.25, which is a “rough average for deep cycle flooded lead
acid.
If you do not wish to calculate “n” use the tables below to select a typical “n” for your battery type.

If after some time or use (6-12months) the accuracy seems to be degrading (possibly due to battery condition,
temperature, age – charging regime) it will be time to recalculate “n”.
Amp hour capacity reset
Amp Hour Capacity reading is reset to Max Battery Capacity when the following conditions occur.
The Battery Voltage is greater than 13.5V (factory default).
The Charge Current is less than 5A (factory default).
See note (a)
Conditions 1 & 2 must be met for 5 minutes.
(a). This should be changed to 4% of amp/hour rating of battery bank ie 220amp/hour bank = 220*4% = 8.8 use
9amps
Charge efficiency
Charging Efficiency is set at 85% (factory default) ie the battery will only accept 85% of the charge current.
This is a difficult parameter to set as after 75% recharge the efficiency will fall off to 0% at full charge. The
overall efficiency will change with temperature, battery condition, charging current/voltage and discharge level.
Trial and error with general usage is the only way to find this efficiency.
Actual capacity
Actual capacity is the present state of charge of Battery bank 1 when the monitor is installed/set up.
Voltage calibration
Factory set, this should not need to be changed.
Amps Calibration
Factory set, Amps Calibration if necessary should be performed under maximum possible load after zeroing
amps at no load.
Reset capacity
Reset capacity provides the option to reset the capacity to the programmed value (YES) or to leave it at the
current monitored level (NO)
Bilge monitor function
The bilge monitor function will be automatically set up when the “Bilge monitor” label is selected for Battery 3
label.
While in bilge monitoring mode, the “C” button to reset the bilge monitor.
To exit the bilge monitor and resume battery monitoring, press the “V” button to return to V1 “Source voltage”.

When an alarm condition occurs, the alarm will sound and
the corresponding display will flash.
To permanently mute any alarm, press the A button for 2

12 Frequently Asked Questions
Q: When calibrating the amps load, the display cannot be changed.
A: You will need to do a factory Reset, Amps zero and then apply a load of more than 10A before you
enter the amps calibration screen in the set up menu.
Q: Screen displays: (DC Amps discharge over range)
A1: This could be normal because you have exceeded the meter rating of 225A
A2: You will need to do a factory reset then apply a load of more than 10A, before you enter the amps
calibration screen in the set up menu.
Q: With no load, there is still anamps reading.
A: The Zero has drifted, you will need to carry out a Zero reset, with no load on the system.
Q: The A/Hrs are not what I would expect.
A1: The batteries could be sulfated.
A2: Re-calculate Peukert's exponent as described on page 7 & 8.
Q: The current display is unstable.
A: Check that a screened twisted pair cable has been used from the shunt to the meter and that it is
installed correctly.
Q: Meter has no amps reading.
A: Check screen wiring on shunt cable; screen from load side (not battery side) of shunt to terminal 8 at
the meter.
Q: “Reset all” is on the display
A: If “reset all” comes up on the screen at any time, the meter has detected a fault. Disconnect power from
the unit and then reconnect. “If reset all” remains on the screen please contact your local BEP agent.
