For the current battery test of the magazine Autozeitung (issue 23/2017), four conventional lead-acid batteries were tested in the field of starter batteries.
Previously, starter batteries were responsible for starting the engine and powering the indicators and lights, however, they now have to provide for several additional power guzzlers such as power steering, water pumps, stop-start systems and, more recently, even turbochargers.
Not forgetting all the handy multimedia features, comfort and connectivity facilities and increasingly, the growing number of useful driver-assistance systems.
In short: Vehicle electrical systems are increasing and, with that, so are the number of functions.
or the current battery test of the magazine Autozeitung (issue 23/2017), four conventional lead-acid batteries were tested in the field of starter batteries. The test batteries had a capacity from 70 to 75 Ah - the size that is common in popular models like VW Golf & Co.
In order to be able to objectively evaluate the capacity and the behaviour during deep discharge, all test batteries came to the battery test plant of FAKT GmbH Kraftfahrtechnisches Prüf- und Ingenieurzentrum (Automotive Testing and Engineering Center). There the batteries were subjected to a bench and cold test in cooperation with GTÜ Gesellschaft für technische Überwachungs (German association for monitoring technical goods).
With the number of discharge cycles - it indicates the cycle life of a battery - the life of the energy storage was evaluated. Another test: After twelve hours in the cold chamber at -20 degrees, the batteries were subjected to the cold starting test.
The intact Start-Power not only impressed in terms of cycle stability, but also set a clear sign against its competitors with 18 successful cold starts.
