SKU: ACT/612 Category: Brand:


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 LOODED (WET) batteries.

What’s In The Box

  • ACT/612 – Intelligent Battery Tester
  • ACT/612TL – Test Leads
  • ACT/430N – Soft Carry Case
  • Sample ACT/BTL Labels
  • Operating Instructions
  • Certificate of Calibration


  • Test SLA, GEL & FLOODED – Simply turn the Ah Calibration Control to select either standby SLA, cyclic GEL and car FLOODED battery types prior to testing. The Calibration Control also allows you to calibrate the battery tester to non standard battery types.
  • For 6V & 12V battery models – Test 6V battery models between 1.2Ah and 12Ah, and 12V battery models between 1.2Ah and 100Ah. With a wide Ah range, the ACT 612 is ideal for testing batteries used in many applications from security, mobility to leisure.
  • Simple Operation – Connect the clamps to the battery, turn the Ah Calibration Control to the desired battery type under test and press the TEST button. It`s that easy. Results will be displayed within seconds.
  • DC Voltage and Ah Capacity Results – There`s no confusing conversion rates or user interpretation needed when using the ACT 612. Two results are displayed the battery`s DC voltage followed by the actual Ah capacity available.
  • 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.
  • Advanced Pulse Load Technology – The ACT 612 uses advanced pulse load technology to analyse Ah capacity, based on the battery`s temperature and state of charge. This method is significantly more accurate than measuring voltage and internal resistance and does not deplete the battery unlike a conventional load tester.
  • Reliable, Continuous Testing – Powered by the battery under test and with ultra low heat generation.
  • Portable – Perfectly suited as a bench tester or out with the engineer.
  • Economical – Identify batteries that still have life remaining and reduce the amount discarded unnecessarily.
  • Profitable – Show the customer the result and increase your own battery sales by recommending a new battery for their system.
