Yes, Rapid charging generates more heat and stress on your battery, leading to faster degradation, whereas home charging at slower rates preserves battery health and extends its lifespan. Let's learn about the C-Rate to find a measure for this:

The C-Rate of a battery is a measure of how quickly it can be charged or discharged relative to its capacity. A 1C rating means the battery can be fully charged or discharged in one hour, while a 2C rating means it can be charged or discharged in half an hour, and so on.

I've been building electric cars since 2018, drove them for 20k miles, and in this post, I’ll provide a quick overview of the C-Rate with numeric examples and a video at the end.

1) A petrol car's starter battery must have a high C-Rating (e.g., 10C), allowing it to discharge quickly to provide a large burst of power to start the engine.

2) An electric fence battery can get away with a low C-Rating (e.g., 0.1C) discharges slowly, providing a steady, low-power output over a long period to maintain the fence's operation.

An Amp-Hour (Ah) is a unit of battery capacity that indicates how much current a battery can deliver over a period of one hour.
