BATTERY TESTING.
1.
BA-5590/U
a.
General. The high cost of high power lithium batteries and the safety aspects of partially depleted
batteries has generated a need for an accurate and reliable capacity meter. The accuracy of the LS-94
is typically +/- 10% of the battery capacity, in an operating temperature range of 1 to 50 degrees
Celsius. Batteries of the following types (BA-5598 and BA-5590) can be tested with the commercial
Energage LS 94. The LS 94 has five status modes and seven state of charge levels, in increments of
10% to 70%. See Energage LS 94 Technical Manual for specifics.
b.
Setup. When turned on, the LS-94 performs a power-on test. This test can be observed from the front
panel display. After power-on test is performed allow the LS-94, 10 minutes warm-up time to ensure
proper results.
SWITCH:
SETTING:
Battery Voltage Selector
15 V
Manufacturer Selector
A (For PCI/PCCI)
B (For SAFT/Duracell)
F (For BA-5588 PCI)
c.
Testing. Testing process takes approximately 2 minutes.
CONNECT:
Battery with appropriate connector cable (each type is different)
PRESS:
The START TEST pushbutton momentarily.
OBSERVE:
The front panel display.
TESTS PERFORMED:
RESULTS POSSIBLE:
OCV (Open Circuit Voltage)
Pass or Fail
OCV (Closed Circuit Voltage)
Pass or Fail
NOTE
If either of these test fail DO NOT RERUN TEST. Dispose of faulty battery.
STATE OF CHARGE:
0 - 10%, 20%, 30%, 40%, 50%, 60%,
70 - 100%
NOTE
When testing old batteries, the RETEST light bar will turn on with one of the CAPACITY light bars.
To verify reading, RERUN test by pressing the START TEST pushbutton. DO NOT TEST a battery
more than three times consecutively.
2.
BA-5372/U
a. SINCGARS RT tests HUB battery. HUB display when flashing indicates weak battery. HUB display (steady)
indicates dead or missing HUB. No HUB display indicates Good HUB.
