The Advantage
The Semi-Automatic Air Leak Test Machine is designed to test the batteries for leakage of the second cover after the heat-sealing machine. This is done by pressurizing the vent holes with overpressure which is then compared with a leak tester at the specified pressure drop rate. The batteries arriving on the conveying system of the machine, enter the automatic testing device separately and are accurately positioned and fixed under the probe. The probe is pressed onto the hole of the battery cover and the battery is pressurized with overpressure. Over a pre-programmed period of time the constancy of the pressure is then measured within a pre-programmed tolerance zone. Should the tolerance zone be exceeded a visual or audible signal serves as a warning of the defective battery. The measured values of different types of batteries are pre-stored. Working method and resetting are carried out automatically.

A semi-automatic air leak test machine tests lead-acid batteries for leaks in the second cover by applying overpressure to the ventilation holes and measuring the pressure drop rate. Batteries are fed individually onto the machine’s conveyor and automatically positioned and fixed under the probe. The test result is monitored electronically within a defined tolerance zone. The semi-automatic design combines automated testing precision with a cost-efficient setup suitable for lower throughput lines.
The fully automatic Premium Line machine handles the entire test cycle without any operator input and is designed for high-throughput production lines. The semi-automatic ECO Line machine offers the same high-precision digital leak detection but at a lower investment level, making it the right choice for smaller production volumes or operations entering automated battery testing for the first time. Both machines use the same overpressure test principle and deliver reliable, traceable results.
Yes. Despite its cost-efficient ECO Line design, the semi-automatic air leak test machine includes a data interface for connecting to line-level data collection systems. It can be operated as a standalone unit or integrated alongside other CMWTEC machines such as the High Rate Discharge Test or Acid Levelling equipment, allowing manufacturers to build up their finishing line step by step.
