This is a 3 part series demonstrating the properties of lead acid batteries. In this video the properties of a lead acid battery under charge and the three stages of charging are shown.
Stage 1 is the bulk charging phase = 0% to ~80% SoC
Stage 2 is the Acceptance phase = 80% to 100% SoC
Stage 3 is Float = maintain at 100% by applying ~13.6v
