Technical Support

The ACT 612 is an intelligent battery tester (IBT) designed for dual-voltage to cover both 6V and 12V lead acid batteries from 1.2Ah to 100Ah, making it capable of testing 12V batteries up to 150Ah.   The ACT 612 is ideal for testing batteries used in many applications from security, automotive, to mobility to leisure.

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 - often used in Start/Stop vehicles), cyclic GEL and car FLOODED (WET) batteries.

When to Recharge or Replace?  Battery manufacturers recommend to recharge or replace a battery when its rated Ah capacity falls below 65%. By giving a clear and accurate Ah reading, the ACT 612 will help you identify replacements quickly and easily.

RoHS Compliant
