Loosely speaking, an automotive charger has a fixed voltage (say 14.7v) and the amperage reduces as the battery voltage equals the charger voltage (water finds its own level). As the state of charge increases, so does the rate of charge slow and the last 20% of the charge is really slow.
Also bear in mind, that gassing (boiling) of a lead acid battery occurs at 14.4v (at average temperatures) and the automotive charger is insensitive to this. If left on through an extended time frame, the electrolyte will evaporate to a dangerously low level - the battery will overheat and internal damage will result. However, the automotive charger can be low in price but must be managed.
Known for its ability to adapt to the state of charge and condition of the battery. The adaptive charger essentially has 3 steps - Bulk, Absorption and Float and sometimes as many as 8.
The adaptive charger is ideal for retaining and holding a battery in a fully charged state over prolonged periods. Ideal for moored vessels, seasonal agricultural equipment and vehicle restoration projects.
The battery conditioner is a low amperage charger at 13.8 volts. It will charge a battery over time but ideal to hold up against parasitic discharge over long periods. It will have a indication LED that will flash on and off when the battery is fully charged. It is quite safe, in fact benificial to leave a 'conditioner / maintainer' charging your battery for long periods of time.
