Schumacher SEM-1562A owner manual Maintain Mode Float-Mode Monitoring, Maintaining a Battery

Maintain Mode (Float-Mode Monitoring)

When the CHARGED LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. If the charger has to provide its maximum maintain current for a continuous 12 hour period, it will go into Abort Mode (see Aborted Charge section). This is usually caused by a drain on the battery, or the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the battery checked or replaced.

Maintaining a Battery

The Schumacher SEM-1562A is a battery maintainer, and maintains both 6 and 12 volt batteries, keeping them at full charge. It can charge small batteries and maintain both small and large batteries. If you are maintaining a fully charged large battery, you will be properly utilizing the battery charger. However, if you use the battery charger to charge a large battery, such as a marine deep cycle battery, that was not fully charged, you may lose some of the battery’s capacity. This would cause the large battery to be unable to hold a charge and become useless. Therefore, we do not recommend charging a large battery with this unit.

NOTE: The maintain mode technology utilized in Schumacher’s maintainers allows you to safely charge and maintain a healthy battery for extended periods of time. However, problems with your battery, electrical problems in your vehicle, improper connections or other unanticipated conditions could cause excessive current draws, as such, occasionally monitoring your battery and the charging process is recommended.

13.CALCULATING CHARGE TIME

Find your battery’s rating on the chart below, and note the charge time given. The times given are for batteries with a 50% charge prior to recharging. Add more time for severely discharged batteries.

CCA = Cold Cranking Amps AH = Amp Hour

RC = Reserve Capacity
