EN 50342

Starter battery performance · Region: Europe

Direct answer: EN 50342 is a europe standard for Starter battery performance of Lead-acid (SLI/EFB/AGM) batteries. European lead-acid starter-battery standard — capacity (C20), CCA at −18°C, charge acceptance, and cycle endurance for SLI, EFB and AGM.

What this standard covers

Test object: Starter battery performance for Lead-acid (SLI/EFB/AGM) batteries. Scope: European lead-acid starter-battery standard — capacity (C20), CCA at −18°C, charge acceptance, and cycle endurance for SLI, EFB and AGM.

Standards define test procedures and pass criteria — the measured values are only comparable when the same standard and conditions apply. See the CCA reference for the standards' measurement context.

How this test is used

EN 50342 is used to assess starter battery performance for lead-acid (sli/efb/agm) batteries in Europe. The result is only meaningful when the sample, conditioning and test conditions match the standard; a number without those details is not comparable.

What to request from a supplier

The exact standard edition and the clause that was tested.
Sample conditioning and test temperature.
The raw data, not only the pass/fail summary.
The laboratory's accreditation scope for this test.

Related standards

Compare with other chemistry-specific standards in the standards index, and check the manufacturer's claimed certificates against the underlying test report.

Common misapplication

Two failures account for most disputes: comparing results obtained at different test temperatures, and treating a supplier's summary as raw data. Ask for the clause tested and the conditioning; if either is missing, the result cannot be compared with another laboratory's.
