thermodynamics

$begingroup$ @哲煜黄, The importance of "internal resistance" depends on how much current and how much voltage the application requires. If the application requires a lot of current, then there''s going to be a lot more voltage drop in cold weather than in warm. If the application can tolerate the voltage drop, then it may be able to use most of the battery''s

What are the different types of lead-acid batteries?

What is a good heat capacity for sealed lead-acid batteries?

Acceptable values for specific heat capacity for sealed lead-acid batteries range between 0.7 and 0.9 kJ/kg-K and value of 0.8 was selected to represent the average of this interval [ 83, 84 ]. For the heat generation variable, a volumetric-based heat model was used.

Is the capacity of a lead-acid battery a fixed quantity?

The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.

What is the heat capacity of flooded lead acid batteries?

Battery-specific heat capacity of flooded lead acid batteries was reported through literature to be slightly over 1000 J/kg-K and thus this value was selected as a reasonable approximation [ 83 ]. Inlet air flowrate was set at 400 cfm which could be easily achieved through an 8′′ duct fan.
