TAGLab BAT100 Battery Tester – Quick Guide
Battery Test
• Connect the red (+) terminal connector cable to the positive (+) terminal of the battery.
• Connect the black (-) terminal connector cable to the negative (-) terminal of the battery.
• With both the battery clamps connected, the tester’s display meter will show the battery’s c rrent state of charge.
• Engine and al electrical accessories m st be off when testing battery.
• If it is less than 12V, disconnect the battery and recharge before re-testing.
• If recharging will not bring the reading above 12V, the battery is defective.
• Press and hold the load switch “ON” for 10 seconds to apply the load to the battery.
• Keep the load switch “ON” till the needle is steady. However do not exceed 10 seconds.
• Read meter with load switch “ON”.
• Release the battery load switch and remove the battery clamps from the battery.
• Refer to the battery analysis table on back of tester or in ser man al
BATTERY ANALYSIS
(Read Meter wit LOAD Switc ON for MAXIMUM 10 Seconds)
LOAD TEST BATTERY CONDITION
Good (Green)
Battery capacity is OK. Battery may or may not be f lly charged.
Check specific gravity of battery to determine state of charge. If
specific gravity is less than f ll charge, check for electrical drain or
possible charging system tro ble. Recharge battery to f ll level.
Weak or Bad,
b t Needle
remains Steady
(Yellow or Red)
Battery capacity is not satisfactory. Battery may be either defective
or not f lly charged. Check specific gravity to determine which
condition exists. If charging does not bring specific gravity to f ll
charge level, battery sho ld be replaced.
Weak or Bad,
b t Needle
remains Failing
(Yellow or Red)
Battery may be defective or very r n down. Release load switch and
note volt meter reaction. Voltage recovery to 12 volt or above within
seconds indicates defective battery. Slow voltage recovery indicates
r n down condition. For best res lts, check specific gravity.
Charging System
(White)
If the display meter needle reads OK, charging system is f nctional.
If it falls on the low red or high red areas, charging system may be
malf nctioning.
