Clear Cover Printer Paper LCD Display Up/Down Button ENTER: function selection / confirm choice 6. Negative Clamp (Black -) 7. Positive Clamp (Red +) - GB.
WARNING： ： 1. Working in the vicinity of a lead acid battery is dangerous. Batteries generate explosive gases during normal battery operation. For this reason, it is of utmost importance, if you have any doubt, that each time before using your tester, please read these instructions very carefully. 2. To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.
necklaces and watches when working with a lead acid battery. It can produce a short circuit current high enough to weld a ring or the like to metal causing a severe burn. PREPARING TO TEST： ： 1. Be sure area around battery is well ventilated while battery is being tested. 2. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes. 3. Inspect the battery for cracked or broken case or cover. If battery is damaged, do not use tester. 4.
Note that nothing will be seen on the display until the tester is connected to a vehicle battery. 3. Make sure the battery terminals are clean. Wire brush them if necessary. Clamp the black load lead to the vehicle negative battery terminal. Clamp the red load lead to the vehicle positive battery terminal. Please clamp on the lead part of the terminal only. Clamping on the iron part of the terminal will lead to wrong test results. 4. Paper load: Open the clear cover.

11. Press the ◄ ► key to select battery fully charged or not if tester asks. Press «ENTER» to confirm choice. IS BATTERY ◄►↵ CHARGED? YES 12. When the test is completed, the display shows the actual volts and the actual CCA or %. {Press the◄ ► key to select: SOH (STATE OF HEALTH) or SOC (STATE OF CHARGE)}. One of six results will be displayed: GOOD & PASS : GOOD & PASS The battery is good & capable of holding a charge. ××.
charge the battery and retest after excluding both previous reasons. If reading is the same, the battery should be replaced immediately. WAITING FOR STABILIZATION: WAITING FOR STABILIZATION For unstable batteries, with enough electrical activity potentially affecting the test results (weak battery and/or recently used batteries), please wait a few minutes for the battery to re-stabilise. Alternatively fully charge the battery then retest. 13. Press the ◄ ► key to select result printing: YES or NO.
SYSTEM TEST 1. 2. 3. - BT501 Press «ENTER» button, you will view the following screen: Turn off all vehicle accessory loads such as light, air conditioning, radio, etc. before starting the engine. Example : SYSTEM TEST ××.××V TURN OFF LOADS START ENGINE When the engine is started, one of the three results will be displayed along with the actual reading measured. CRANKING VOLTS NORMAL The system is showing normal draw. Press «ENTER» to perform the charging system test.
LOW CHARGING VOLTS WHEN TEST AT IDLE The alternator is not providing ALT. IDLE VOLTS sufficient current to the battery. ××.××V LOW Check the belts to ensure the alternator is rotating with engine running. If the belts are slipping or broken, replace the belts and retest. Check the connections from the alternator to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest. If the belts and connections are in good condition, replace the alternator.
8. When testing older model RUN ENGINE UP TO diesel engines, the users need 2500 RPM 15 SEC. to run up the engine to 2500 rpm for 15 seconds. You will view the screen as follows: 9. Press «ENTER» to look for the amount of ripple from the charging system to the battery. One of two testing results will be displayed along with the actual testing measured. RIPPLE DETECTED NORMAL Diodes function well in the alternator / stator. RIPPLE DETECTED ××.
connection issues, replace the regulator. Since most alternators have the regulator built-in, this will require you to replace the alternator. CHARGING SYSTEM LOW WHEN TEST WITH ACCESSORY LOADS ALT. LOAD VOLTS The alternator is not providing ××.××V LOW sufficient current for the system’s electrical loads and the charging current for the battery. Check the belts to ensure the alternator is rotating with the engine running. If the belts are slipping or broken, replace the belts and retest.
GLOSSARY What is a GEL battery? A gel battery is a lead-acid electric storage battery that: is sealed using special pressure valves and should never be opened. is completely maintenance-free.* uses thixotropic gelled electrolyte. uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications). is non-spillable, and therefore can be operated in virtually any position.
What is CCA (COLD CRANKING AMPS)? The current in amperes which a new fully charged battery can deliver for 30 seconds continuously without the terminal voltage falling below 1.2volts per cell, after it has been cooled to 0OF and held at that temperature. This rating reflects the ability of the battery to deliver engine starting currents under winter conditions. What is AMPERE-HOUR? The unit of measurement of electrical capacity.
