Battery Load Tester Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9398
Jlab Export is a leading Battery Load Tester Manufacturer,and suppliers in India
A battery load tester draws a heavy current from a battery for a short time and shows how far the voltage falls. A good battery holds its voltage, a weak one sags. This tester also checks the starter, alternator, voltage regulator and related circuitry, in a 20 second test. It has a stainless steel housing, heavy duty cables and copper plated clamps.

Practicals Using the Battery Load Tester
A standard first practical is to charge a battery, load-test it and then check every cell with the Battery Hydrometer. One cell that stays low on the hydrometer usually explains a failed load test. Students then repeat the test on a partly discharged battery to see how state of charge changes the result.
On a running engine such as the EFI Petrol Engine Test Bed, students watch the battery voltage while cranking and again at idle and higher speed. This shows whether the starter, alternator and regulator are working. The diode test on the Hand Held Tune-Up Analyzer then helps to trace a charging fault to the alternator.
Frequently Asked Questions
Why load-test a battery instead of just reading its voltage?
A worn battery can show normal voltage with nothing connected and still collapse when the starter draws current. The load test copies that heavy draw, so it shows the real condition of the plates and cells.
Does the battery need to be charged before the test?
Yes. A discharged battery will fail a load test even when it is healthy. Charge it first and let the surface charge settle, then test. If it still fails when fully charged, the battery itself is at fault.
How is the starter checked with this tester?
Connect the clamps to the battery, stop the engine from firing and crank it for a few seconds. If a good battery drops much further than normal, the starter is drawing too much current. If the voltage stays up but the engine turns slowly, look for a high-resistance cable joint.
How do I check the alternator and voltage regulator?
With the engine running, the battery voltage should rise above its resting value. It should then hold steady as engine speed goes up. No rise points to the alternator, its belt or wiring. A voltage that keeps climbing with speed points to the regulator.
Can the tester be used again straight after a test?
The load element heats up while it carries current, so keep each test within the 20 second period and let it cool before the next one. Work in a ventilated place, since a battery under test can give off gas.
