ACT612 Intelligent Battery Tester
The indicated price is valid ordering till 12.06.2026.
The ACT ACT612 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 batteries up to 100Ah. 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.
ACT612 contains advanced pulsed load analysis tecknology which removes surface charge to accurately measures the available Ah capacity based at the battery's temperature and state of charge. This enables you to check the voltage and capacity of new batteries straight from the box and identify used batteries which show abnormal Ah capacity caused by excess temperature or from being under or overcharged. A table on the back of the meter indicates when batteries should be recharged or replaced.
Advanced Features:
• Tests 6V/12V SLA, GEL and Flooded lead acid batteries
• Capable of testing 12V batteries up to 100Ah
• Displays DC voltage and Ampere-hour (Ah) capacity available in the battery
• Advanced pulse load analysis accurately measures Ah capacity available in seconds
• Accurate Ah capacity based on battery's temperature and state of charge
• Unique ‘Ah Calibration Control’ enables standby SLA, cyclic GEL and car FLOODED batteries to be tested
• Ultra low heat generation allows continuous battery testing
• State-of-the-art reverse polarity protection
• Replaceable plug-in test leads
• Calibration Certification included
• Ideal for those who need to test a broad range of lead acid batteries types in various applications such as alarm systems, UPS, golf, mobility and leisure etc.
