TESTING S EQUENCE
There arefourbasic s teps required to
usethe71225 asabattery t ester.
1.Connect thecharger battery c lamps t o
thebattery. Besure tofollow allofthe
precautions listed under "OPERATING
INSTRUCTIONS".
2.Connectthecharger power cordto a 120V
AC 2-prong wall o utlet. Again, besure to
follow alloftheprecautions listed under
"OPERATING INSTRUCTIONS".
3. If necessary, pressthe BATTERY
TYPE button until t hecorrect typeis
indicated.
4. Read t hevoltage o nthedigital display
orpress t hedisplay m ode b utton t oset

TESTER A ND CHARGER
When f irst t urned o n, t he71225 o per-
ates only asatester, notasa charger. To
continue touseitasonly atester, avoid
pressing theCHARGE RATE s witch b ut-
ton. S electing acharge r ate activates the
battery charger and deactivates the tester.
Pressing theCHARGE RATE b utton w hen
the8OA S tart L ED islit(except during t he
180 second c ool down) will s hut o ff t he
charger and activate thetester.
POWER-UP IDLE TIME LIMIT
If no switch button is pressed within 15
minutes after the battery is first powered
up, the charger will automatically switch
from tester to charger, if a battery is
connected. In that case, the battery will
be set for the 2A charge rate and 12V
REGULAR battery type.
TESTER WITHOUT TIME LIMIT
If either the DISPLAY MODE or BAT-
TERY TYPE button is pressed within
the first ten minutes after the battery is
I1
powered up, the battery will remain a
tester (not a charger) indefinitely, unless
a charge rate is selected.
TESTING AFTER CHARGING
After the battery has been changed from
tester to charger (by selecting a charge
rate), it remains a charger. To change
the battery back to a tester, press the
CHARGE RATE switch until all charge
rate LEDs are off.
TESTER STATUS LEDs
When the 71225 is operating as a bat-
tery tester, the status LEDs light under
the following conditions:
• The CHARGED (green) LED will light if
a charged battery is tested.
• The CHARGING (yellow) LED does not
light in the battery test mode.
• The CHECK (red) LED lights unless a
properly connected battery is detected.
• When the tester display mode is set to
VOLTAGE, the CHARGED and CHARG-
ING LEDs won't light.
INITIAL PERCENT CALCULATION
When a battery % is calculated for the
first time after connecting a battery, the
digital display will show three dashes
("---") for a period as long as several
seconds while the tester analyzes the
battery.
NOTES FOR TESTING BATTERY %
A recently charged battery could have a
temporarily high voltage due to what is
known as "surface charge". The voltage
of such a battery will gradually drop during
the period immediately after the charging
system is disengaged. Consequently, the
tester could display inconsistent values
for such a battery. For a more accurate
reading, the surface charge should be
removed by temporarily creating a load on
the battery, such as by turning on lights or
other accessories.
The battery % ranges from 0 to 100.
The battery tester is only designed to test
batteries. Testing a device with a rapidly
changing voltage could yield unexpected
or inaccurate results.
