Cold Temperature Effects
•
A battery will test lower when cold than when warm. For more accurate results, please reduce the battery’s
nominal rating by 200 CCA (one step on meter scale) for each 10°C drop below +5°C. If display meter CCA
rating is 800 and battery temperature is -5°C, read the same as 600 CCA (i.e. 1 step down).
