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 0°F an equivalent lead acid battery will outperform a 
lithium battery (see the graph below).
