SIST EN 50342-1:2016/A1:2019

Lead-acid starter batteries - Part 1: General requirements and methods of test

This European Standard is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as a power source for the starting of internal combustion engines, lighting and also for auxiliary equipment of internal combustion engine vehicles. These batteries are commonly called “starter batteries”. Batteries with a nominal voltage of 6 V are also included within the scope of this standard. All referenced voltages need to be divided by two for 6 V batteries.
This European Standard is applicable to batteries for the following purposes:
− batteries for passenger cars,
− batteries for commercial and industrial vehicles.
This European Standard is not applicable to batteries for other purposes, for example the starting of railcar internal combustion engines or for motorcycles.

Overview

EN 50342-1:2015/A1:2018 (CLC) - Lead‑acid starter batteries - Part 1: General requirements and methods of test - defines general requirements and standardized test methods for 12 V (and 6 V) lead‑acid starter batteries used primarily for starting internal combustion engines, vehicle lighting and auxiliary equipment. This CENELEC amendment (A1:2018) updates test procedures, labeling and charging recommendations for passenger cars and commercial/industrial vehicles (excluding motorcycles and railcar engines).

Key topics and technical requirements

• Scope and voltages
  • Applies to nominal 12 V starter batteries; 6 V batteries are included (all referenced voltages are halved for 6 V types).
• Capacity definitions and tests
  • Defines the 20‑hour nominal capacity (C) and the effective capacity (Ce) determined by constant‑current discharge to a final voltage Uf = 10.50 V.
  • Test sequencing rules for calculating mean 20‑h capacity over battery samples are specified (modifications clarify which test steps to use).
• Cranking performance
  • Standardizes methods to verify cranking performance alongside capacity; combination of capacity and cranking tests is considered as test blocks with pass/fail criteria.
• Charging procedures
  • Recommended charging voltages clarified (e.g., 14.4 V for VRLA, 15.6 V for flooded types referenced to EN 50342‑4).
  • Specific recharging regimes are defined (example: recharge for 6 h at 16.0 V or 14.8 V for VRLA with current limits).
• Safety labelling
  • Requires the six coloured safety signs defined by ISO 7010 (no open flame, eye protection, no children, corrosive, refer to manual, explosive) to be grouped on the battery top, minimum dimensions and guidance on vehicle/manual placement.
• Administrative/technical updates
  • Amendment A1 adjusts tables, test steps, bibliographic references (e.g., replacing ECE 37 with ECE/TRANS/WP.29/343 Regulation 37) and editorial clarifications.

Applications and users

This standard is essential for:

• Battery manufacturers (design verification, production QA)
• Independent test laboratories (type approval, compliance testing)
• Automotive OEMs and suppliers (component specification and procurement)
• Regulatory bodies and certification authorities (market surveillance)
• Aftermarket battery distributors (labelling, warranty documentation)

Related standards

• EN 50342‑4 (charging algorithms and requirements) - referenced for charging voltages
• ISO 7010 - safety signs for labelling
• ECE/TRANS/WP.29/343 Regulation 37 - vehicle/battery regulations referenced

EN 50342‑1:2015/A1:2018 provides a uniform test and labelling framework that helps manufacturers and regulators ensure starter batteries meet repeatable performance, safety and compatibility expectations across Europe.
