Ctek System Battery Monitor 100A

The CTEK System Monitor 100A is a professional battery monitoring system designed for the precise measurement and analysis of 12V lead-acid batteries, including AGM, gel, and calcium types. This advanced monitoring device provides real-time data on battery voltage, current, and state of charge via its clear digital display, allowing users to make informed decisions regarding battery maintenance and replacement. With dimensions of 120 mm x 85 mm x 35 mm and a weight of 180 g, the compact unit features a robust ABS plastic housing designed to operate in temperatures ranging from -20°C to +60°C. The monitor connects directly to the battery terminals using the included 2.5 mm² cables with ring terminals and includes a temperature sensor for accurate compensation. It offers multiple measurement modes, including continuous monitoring, load acceptance testing, and cranking voltage analysis with data logging to track battery performance over time. The device operates with 9-16V DC at a maximum current measurement range of 100A and a voltage accuracy of ±0.1V. Its IP65-rated housing protects against dust and water jets, making it suitable for automotive, marine, and stationary power applications. The System Monitor 100A does not require an external power source when connected to an active battery and includes extensive mounting materials for flexible installation. This monitoring system represents the successor to previous CTEK battery analyzers and integrates improved measurement algorithms and an optimized user interface based on professional user feedback.
