2. Load testing may require use of battery side terminal
adapter to insure good connections (see Fig. 6D-10).
b. Connect a voltmeter and a battery load tester across
the terminals.

c. Read voltage after 15 seconds with specified load
applied (see Figure 6D-1 l), then disconnect load.
d. If voltage does not drop below the minimum listed in
Fig. 6D-12, the battery is good and should be fully charged,
cleaned, and returned to service.
e. If voltage drops below the minimum listed, replace the
battery.

CHARGING PROCEDURES
When it is necessary to charge a battery, the following
safety precautions must be followed:
1. If the electrolyte temperature is above 125°F. (52"C.),
discontinue charging or reduce charging rate.
2. If violent gassing or spewing of electrolyte through the
vent caps or holes occurs, discontinue charging or reduce
charging rate.

MINIMUM VOLTAGE
3. Charging should also be stopped when 1) green dot
is visible in sealed battery, 2) specific gravity no longer
changes over a two hour period in conventional battery.
Charge the battery according to Figure 6D-13 below.
The adapters shown in Fig. 6D-10 may be needed.
When the maximum time in Figure 6D-13 is reached for
charging the sealed battery, charging should be stopped even
if the green dot is not visible. It should be noted that these
times are approximate and for reference only. Temperature
of the battery, as well as age and condition of the battery, will
affect the charging time. Also, most charging equipment will
not charge at a constant amperage. The most satisfactory
charging is accomplished at a slow charging rate. Whenever
possible, the slow rate should be used.
