ETX1200-24-VNT Discharge Capacity
Discharge Versus Temperature
We use a similar Cold Cranking Amp test standard as the lead acid battery manufacturers
(SAE test performed at 0°F, but 3 second discharge time vs 30 second). As such, our
battery with a similar CCA rating as a lead acid battery should provide the same cranking
performance at 0°F. But below -17°C (0°F) an equivalent lead acid battery will
outperform a lithium battery (see the graph below).
