ACT 612 Intelligent Battery Tester
The ACT 612 Intelligent Battery Tester provides fast and clear checks for common lead-acid batteries. It measures the DC voltage and shows the available ampere-hour capacity. As a result, engineers can assess battery condition in seconds rather than waiting for a full discharge test.
Designed for 6 V and 12 V batteries, the tester supports standby SLA, cyclic GEL and car flooded types. It tests 6 V batteries from 1.2 Ah to 10 Ah and 12 V batteries from 1.2 Ah to 100 Ah. Two different set types are available to suit different testing needs.
Fast Battery Capacity Checks
Instead of carrying out a full 20-hour C20 discharge, the ACT 612 Intelligent Battery Tester simulates the test in a much shorter time. Once connected to clean battery terminals, it first displays the DC voltage. It then shows the actual Ah capacity available within seconds.
Advanced pulse load technology assesses the battery using its temperature and state of charge. Therefore, the test gives a more useful capacity reading than checks based only on voltage and internal resistance. The process also avoids the high drain linked with a standard battery load tester.
Simple Testing for Lead-Acid Batteries
A calibration control lets the user select the required battery type before testing. It can also help match the unit to different lead-acid technologies or specific battery brands. This makes the ACT 612 Intelligent Battery Tester suitable for varied service and maintenance work.
Clear results help users decide when a battery may need charging or replacement. Battery makers commonly advise action when the rated Ah capacity falls below 65 per cent, and the supplied guide helps users compare common battery sizes. With simple controls and no complex settings, the ACT 612 Intelligent Battery Tester supports quick testing across security, telecoms and mobility work.
