The Battery Load Tester is an important instrument in checking the batterys performance on load. On open circuit, the battery may display appropriate voltage, but the actual battery condition can be judged only by checking the battery voltage on load, i.e., by loading it to an appropriate current. The Battery Load Tester unit, when connected to the battery under test, initially indicates the battery voltage on open circuit. Subsequently, it loads the battery for 5 seconds, and monitors & displays the on-load battery voltage. On the basis of this voltage, the battery is adjudged as GOOD, WEAK or BAD.

High Rate Discharge Testers are designed to test crankingperformance of Automotive (SLI) Batteries as per various National and International specifications. The unit comprises of Electronic Active Load to discharge Battery at high current. (Normally at 3*C20 or 5* C20) keeping the current constant through out the test. The test is terminated automatically when the Battery reaches the preset End Voltage.Micro processor based digital timer with non volatile memory records the discharge time precisely up to 0.01 seconds. The unit is rated for short duty of Max. up to 10 minutes. However it can be used for continuous discharge at lower currents (30% of its max. capacity) to test Capacity of Battery at C1, C3, or C5 ratings.

PRODUCTION LINE TESTER:

ELIND Production Line Tester is used for routine Pre dispatch testing of batteries to ensure that the battery is free from manufacturing defects like poor inter cell joints, missing separators, lead tree shorting etc. This checks the performance of battery under high discharge current. The test takes only 5 seconds and is recommended on 100% batteries to avoid faulty batteries leaving the manufacturing unit.

ELIND Rated Capacity Tester is used for measuring Ampere Hours Capacity of battery at desired rate viz., C20, C10, C5 etc as per various National as well as International specifications. It comprises of electronic active load to discharge Test Battery at constant current which can be set precisely to desired level by adjusting a multi turn potentiometer. The test is terminated automatically when the battery voltage reaches the set END voltage and the time of discharge Ampere Hours discharged is recorded precisely on digital Timer or Ampere Hour meter.

Elind Battery Universal Testeras the name suggests, is a versatile multi testing station designed to test all types of lead acid as well as Ni-cd Batteries as per various National and International specifications. The unit can be used for conducting any of the following tests.

• Capacity test
• Charge / Discharge Cyclic Test
• Endurance Test / Resistance to over charge test
• Ampere Hour / Watt Hour efficiency test
• Charge Acceptance test
• Water loss test
• Retention of charge test

The unit comprises of electronically controlled constant current / constant voltage Battery charger and constant current discharger, along with Micro controller based programmer with LCD display to set Charge / Discharge / Pause program sequence, Charge / Discharge current and Step termination parameters like time, voltage, Ampere hours and number of cycles etc.

Built in data logger sends test data to a printer or to a personal computer at set time interval. Test data can be printed on a 80 column serial printer or recorded / displayed on personal computer through user end PC software. Stored data can be used to draw graphs of voltage / Current / AH / Temperature / Time as per requirement.
