The Schumacher SS-210A Ship ’N Shore is the perfect answer for multiple marine capabilities. With two sets of output cords this unit can charge 2 separate 12 volt batteries at the same time at a true 10 amp charge rate or a single 12 volt battery at a true 20 amp charge rate. Charges both 12 and 24-bolt battery systems. Ignition protected, non-sparking, battery connection leads make it safe to recharge, even on board. Unit is waterproof and is approved for mounting on the weatherdeck.
Automatic Charge Mode
The automatic charger uses a three-step charging process. During the bulk charge phase, the charger attempts to deliver 10/(20) amps of current to the battery(ies) until the battery voltage levels off. At this point, the SS-210A enters the absorption charge phase. In this phase, the charger will hold the battery voltage constant and let the battery determine the charging current. When the charging current stabilizes, the charger will continue to charge for three hours to bring the battery up to full charge. The charger will then automatically enter the maintain mode. During this phase, the charger will hold the battery voltage constant at 13.2 volts to guard against self-discharge of the battery. The charge current will typically be a few tenths of an amp.
Desulfation Mode
If the battery has been left discharged for an extended period of time, it may have become ‘sulfated’. If the battery voltage is less than 12.2 volts prior to being charged, and the voltage climbs rapidly when charging begins, the battery may be sulfated. Under this condition, the charger enters desulfation mode. The charger will stay in desulfation mode for up to 24 hours, attempting to break down the sulfation. If the battery current increases to normal in this time, the charger will enter the normal automatic mode. If the current does not increase to normal, the charger will enter the abort state and will shut off. The rapid flashing of the red led indicates the abort state and the battery may need to be replaced. The charger will remain in abort until the AC power is removed.
Extended Battery Storage
The SS-210A will draw a small amount of current from the battery(ies), a few milliamps, when not charging or maintaining. If the battery(ies) are going to be stored for an extended period of time (several months) without being charged, it is best to disconnect the leads or remove the fuse to keep the charger from discharging the battery(ies) over time.
