Charge the battery fully, and check it with a volt meter. You must get a reading of 12 volts or more for a good battery. A reading of 10.5 volts or less indicates that one or more of the cells have shorted out. The shorted cell is preventing the battery from holding a full charge.
You would use 10 amperes on a car battery and 2 ampere on whatever small batteries you might want to charge that still use the same voltage. For example, a motorcycle battery could use the 2 ampere charging option.
Yes, disconnect both + and – terminals and then charge by connecting the charger wires in order of Red for + and black for -, do not interchange. be appropriate to disconnect the positive terminal.
