This is where the charger will do the most work, recharging batteries that are severley flat. The highest voltage & ampage which the charger is rated at will be used|Step 2: Absorption Stage. Now that the battery has reached 80% of charge, the intelligent charger will begin to steady the voltage used and ampage will decline.
