If a 12V battery drops below a certain voltage threshold (usually around 2 to 4 volts), standard manual chargers cannot detect it or initiate a charge. The battery may need professional reconditioning or replacement. The charger gets warm to the touch
The 4 amp rating is a rough guide. For a 65Ah battery, an 8A charger would take about 8 hours to recharge from fully flat. Because your BX60 is a 4A charger, it will take roughly twice as long. A battery at 50% charge might take 8-10 hours or more.
