TS EN 50342-1

TS EN 50342-1 addresses general requirements and test methods for 12 V lead-acid starter batteries. It provides the basic technical framework for batteries used in internal combustion engine vehicles, mainly as a power source during starting and also for lighting and auxiliary equipment.

The technical role of starter batteries

Lead-acid batteries are widely used in starting applications because they can deliver high current for a short period and have a well-established vehicle electrics profile. A starter battery is different from a battery intended mainly for long-duration energy storage: the key concern here is high cranking performance rather than deep-cycle service. The 12 V nominal rating reflects compatibility with common vehicle electrical systems and typical onboard loads such as lighting and auxiliary devices.

What this part covers in practical terms

• The standard applies to lead-acid batteries with a nominal voltage of 12 V.
• Its primary use is as a power source for starting internal combustion engine vehicles.
• Lighting and auxiliary equipment are included in the application context.
• The document combines general rules with test methods.
• This listing represents a withdrawn edition of TS EN 50342-1.

From a general engineering perspective, standards of this kind support consistent evaluation of capacity, starting performance, durability, and construction suitability. They help make battery types comparable under a common terminology and make product selection clearer in vehicle electrical applications.
