Requirements and Norms of SLI-Batteries in the North European Climate 890015

SLI battery norms effect the performance of a battery in cold starts both directly and indirectly. The indirect influence is for instance due to the prevailing figure of merit, CCA amps (SAE) or 20 h capacity (DIN). The European norms seem to lead to batteries with insufficient cranking power at low temperatures. The SAE norm encourages the manufacturer both directly and indirectly to lower the battery resistance, which results in a higher cranking power and thus in a battery better suited to northern weather conditions.
