The Batterytester AT04 is a professional battery tester for fast and accurate testing of batteries, ranging from a single cell to complete battery packs with a maximum voltage of 102 V.

The tester is designed for daily use in workshops, service organisations, battery specialists and other professional environments where a reliable assessment of battery condition and capacity is important.

A key advantage of the AT04 is its ease of use. Different battery types can be pre-configured in the software with the correct test settings. This means the user does not need to enter all parameters again for each test, allowing batteries to be tested quickly, easily and according to a consistent method. This makes testing reproducible and reduces the risk of input errors.

The AT04 can test with a high discharge current of up to 60 A. This allows lead-acid batteries in particular to be tested significantly faster than with traditional capacity tests. For example, a lead-acid battery can be tested using the C3 method, enabling a reliable capacity measurement within a relatively short period of time.

During the test, important battery data is measured and recorded. Based on these results, the available capacity and State of Health (SOH) of the battery can be determined.

The included PC software makes it possible to manage batteries and test settings, store test results and generate a clear, professional battery test report. This allows test results to be documented, retrieved and shared easily with customers or within your organisation.

Thanks to its wide voltage range, from a single cell to complete battery packs up to 102 V, and its adjustable test current, the Batterytester AT04 is suitable for a wide variety of battery applications. The combination of speed, ease of use, reproducible testing methods and professional reporting makes the AT04 ideal for organisations that regularly test batteries and need to reliably document their technical condition.
