The ACT 6/12 battery tester simulates a full (20 hour) battery discharge test in seconds. The ACT/612 is a dual voltage intelligent battery tester, designed for 6V and 12V lead acid batteries from 1.2Ah to 100Ah, making it capable of testing 12V batteries up to 150Ah. It’s the only product of its kind to have an Ampere-hour (Ah) calibration control, enabling Ah readings to be adjusted to suit various battery technologies including standby SLA (AGM), cyclic GEL and car FLOODED (WET) batteries.

The ACT/612 contains advanced pulsed load analysis technology which removes surface charge to accurately measure the available Ah capacity based on the battery's temperature and state of charge. This enables you to check the voltage and test the capacity of new batteries straight from the box, as well as used batteries which may show abnormal Ah capacity caused by excess temperature or from being under or overcharged.

A table on the front of the meter indicates when batteries should be recharged or replaced due to age or operating conditions (65% of rated capacity). The ACT/612 is designed for those who need to test different types of lead acid batteries quickly and easily.
