So we have simplified some of the highlights we gained from the lithium vs lead acid study, and explain how it impacts you. When subjected to a 30amp draw (less than 400watts) at a room temperature of roughly 70 degrees Fahrenheit (21C), the lead acid batteries were only able to deliver 63 of their claimed 210 amp hours of power.
For lead-acid batteries, a higher temperature can increase the rate of sulfation, which can reduce the battery''s cycle life. Sealed batteries, on the other hand, are less affected by temperature and can last longer than flooded lead-acid batteries. ... found that increasing the temperature from 77 degrees Fahrenheit to 113 degrees Fahrenheit ...
Temperature considerations by chemistry. Lead Acid. Lead acid batteries often have a fairly narrow temperature window and cannot function or offer long life cycles in cold or hot weather.
