Battery tester

The 6V/12V 80A Battery Load Tester with Resistance Test is designed for practical battery inspection and controlled load testing. Supporting both 6V and 12V batteries, this model provides a straightforward solution for checking battery voltage and internal resistance in automotive service, battery retail, and maintenance applications.

The tester features an 80A load test current and is suitable for batteries with capacities from 40-200Ah. A built-in auto timer operates during the load test to help control the testing period and prevent damage to the tester caused by excessive or prolonged loading. This function makes the unit more convenient for routine battery testing and repeated service operations.

The tester also features an auto data hold function, allowing test information to be retained for easier viewing during operation. Voltage can be checked through both load and unloaded tests, providing useful information about battery performance under different testing conditions. In addition, the unit can measure the internal resistance of the battery, providing another reference for evaluating battery condition.

With its combination of 6V/12V compatibility, 80A load testing, automatic timing, data hold, voltage testing, and internal resistance measurement, this model is positioned as a practical load-oriented battery tester. Its focused functionality makes it different from more advanced battery analyzers that emphasize CCA, vehicle charging systems, or extensive battery health diagnostics.
