Battery Test Procedure
The condition of the control battery is tested by depress-
ing the BATTERY TEST key on the operator panel. No
external current/voltage meter is necessary for testing.
The control performs a self-test every 12 hours or when initi-
ated by an external command. When a battery test is initiated,
the spurious charge is first drained to allow the battery voltage
to equalize. A 10-ohm, 55-watt resistor is then placed across
the battery terminals and a voltage drop is calculated. If the
drop from the equalized voltage to the test voltage exceeds 2
volts, then the CHECK BATTERY LED is illuminated.
To perform a battery test:
1. Using the NEXT and BACK keys, scroll through the
LCD display to Screen 31, the Battery Monitor screen.
2. Record the NORMAL VOLTS and NORMAL CUR-
RENT readings from the screen.
Note: Voltage should be between 25 to 31 volts with
higher readings at colder temperatures. Under nor-
mal conditions with ac connected and the battery
trickle charging, the current should read less than
20 mA. With ac connected and in bulk charging
mode, current will range from 12 to 600 mA. With ac
disconnected and the battery supplying the load,
current will read -180 mA to -600 mA depending on
accessories connected.
3. Momentarily, press the CHANGE/LAMP TEST key,
then BATTERY TEST key.
Note: AC power can be either connected or disconnected.
4. Record the TEST VOLTS reading from the LCD and
the status of the CHECK BATTERY LED. Service the
battery if the CHECK BATTERY LED is illuminated.
Testing Procedure for Uninstalled
Battery
The entire process should be conducted in a clean envi-
ronment, such as a repair shop.
Refer to Table 4 and follow this procedure to perform a
bench test on a control battery in a service shop:
1. Remove the control from service. Refer to Remove
the Control from Service procedure within the Test-
ing section of this manual.
2. Remove the battery from the control and carefully
transport it to a suitable service facility.
3. Measure battery voltage.
4. Apply test load and measure battery voltage after 5 sec-
onds of load to determine voltage drop. Refer to Table
4 for Bench Test Load Condition.
5. Remove test load.
If the battery fails the test or is at least four years old, it
should be replaced. Refer to Table 4 for battery catalog part
numbers.
Battery Charging
If it is not possible to charge the battery with the control’s
built-in charger, a KA43ME7001 (120 Vac) portable bench
type battery charger is available. Refer to Service Infor-
mation S280-79-14 KA43ME7001 Portable Lead Acid
Battery Charger Instructions for additional information.
Use adapter KME5-325-1 to connect the two 12 volt bat-
teries to the KA43ME7001 charger. Charge the battery
with a KA43ME7001 (120 Vac) portable charger.
Note: A red LED indicator on the body of the charger illumi-
nates when charging.
The charger senses when the battery voltage reaches
2.27 volts per cell, then the charge rate reduces to main-
tain a trickle charge.
The red LED flickers to indicate the battery has reached a
full charge. This process can take up to 24 hours.

TABLE 4
Battery Bench Testing and Replacement Information
The Form 5/Triple-Single control batteries have different dimensions; therefore, if the replacement battery ordered is a different brand
than the original battery, a kit with mounting hardware may be required to accommodate the replacement battery size.

CAUTION:
Recloser misoperation. The control
must be removed from service before disconnecting
the control battery. Disconnecting the control battery from an
in-service control may cause recloser misoperation (uninten-
tional operation). Failure to comply can result in equipment
damage or personal injury. T213.4
