Guys this is a question that I should know the answer to but don't. If I use a 10 amp charger and the ammeter only show 3-4 amps in the beginning, why does it not go up to 10 amps then show lower amperage as it charges?
With buzz box chargers, the amount of current is related to the resistance of the battery and the state of charge. A totally dead battery has less resistance, and will pull more current than one that is close to full.
If a dead battery is not pulling current, then the battery is bad.
