DISCHARGE / CAPACITY TEST
24 VOLT SLAB
a) Set Timer to 60 minutes.
b) Set low cutoff Voltage (12) to 18.0 Volts.
c) Set Constant Current Discharge (15) to the C Rate (e.g. 30 amp-hr battery
set to 30.0 amps).
d) Accept – If the Timer times-out before the battery voltage lowers to cutoff
occurs before the timer times-out.
e) Fail – If cutoff occurs before the timer times-out.
24 VOLT NiCads
Same as SLAB, except Set Voltage Cutoff to 1.0 Volt / Cell.
12 VOLT BATTERIES
Same, except Set Cutoff to 9.6 Volts.
II.
CHARGING, GENERAL:
The voltage and current adjustments will provide the voltage and currents for Ni-
Cad or Vented or Sealed Lead Acid batteries and other battery chemistries and
voltages. The 4159 unit will charge all 12 and 24 volt batteries including starting
batteries, single cells, emergency batteries such as Inertial Navigation, Inertial
Reference (24 cell NiCad). The 4159 will charge in either the Constant Potential
(voltage) or Constant Current (amperes) mode depending on the setting of the Charge
Voltage Adjust (6) or Charge Current Adjust (5).
A. OPERATION: 24 VOLT SEALED LEAD-ACID BATTERIES (SLAB)
Set-Up and Procedure (with battery disconnected)
Note 1: Potentiometer knobs have knob locks. The settings will remain for any
subsequent operations.
Note 2: The 4 potentiometer adjustments on the panel are multi-turn (10 turns).
1.
Remove the temperature plate from the cable well, plug the cable from the
temperature plate into the panel jacks “Overtemp Cutoff Thermostat” (9), place
the battery on the plate.
