How battery performance is measured and verified — capacity, CCA, load, resistance, cycle and safety testing, with the applicable standards.

Start with the performance claim you need to verify, not with the test name. Capacity, cold-cranking, cycle life and abuse tolerance answer different questions and use different samples. Each method page states what the test measures, what it does not measure, and the standard that governs it. If a supplier's report does not state the standard edition, the conditioning and the raw result, treat the claim as unverified.
We do not test products, issue certificates or rank manufacturers. This is a reference for buyers who need to ask better questions and read a test report critically. The published standard and the accredited laboratory's report are the authoritative documents.

A controlled discharge at the specified rate, temperature and cut-off voltage. A label capacity is a nominal figure, not a test result.
Only if it states the standard edition, clause, conditioning and raw data, and comes from a laboratory accredited for that test.
CCA is measured at −18°C for 30 seconds to a voltage threshold; CA is measured at 0°C. The numbers are not interchangeable.
