UT673A/UT675A Battery Tester
Overview
UT673A/UT675A battery tester, with its leading-edge conductivity test technology,
accurately and rapidly helps users to measure the cold cranking amps capability of the
vehicle starting battery, healthy state of the battery itself, detect the common fault of
vehicle starting and charging system, which helps repair vehicle quickly.
Safety information
Please carefully read this manual and follow the warning and safety information before
use.
To avoid fire and overcurrent, please read all rated values and symbol descriptions
before use.
Do not open the case cover. Do not turn on the tester if its cover or front panel is open.
Do not touch the connectors and components if the tester is powered on.
Please contact the authorized repair personnel to detect, repair, maintain the tester
if you find any fault on it.
Do not use in humid, explosive or inflammable environment.
Keep the tester surface clean and dry. Keep it well-ventilated.

If the standard is not found,
estimate CCA value according to
the battery capacity.
Operation instruction
1. Connect the red and black clips of tester to the measured battery, red is positive,
black is negative, the tester screen will display startup interface. If the battery voltage
is lower than 7.0V, the test will become abnormal.

good condition,
please charge
the battery.
Retest after charging
Replace the battery
The battery is in bad
condition, replace
the battery.
The performance of storage battery is good,
please continue using the battery.
Because the voltage of storage battery is lower
than 12.3V, so the performance of storage
battery is good, please continue using the
storage battery after it is fully charged.
Because the battery voltage is lower than 12V, so please
retest after it is fully charged. Incorrect reading may occur
if the battery is not fully charged. Please replace the battery
if “Retest after charging” displays again after charging.
Replace the storage battery.
Battery inside is damaged, replace the storage battery.

NOTE: For low-capacity battery (For example, the vehicle is shut down for a long
time, the battery is not charged in time, the battery power is significantly lost
because the vehicle door is not closed.), the tester may prompt you to “Replace
battery” during actual measurement, please consult the storage battery factory
and charge the battery according to the designated method, and then retest.
