REV 14l
Read this material before using this product.
Failure to do so can result in serious injury.
SAVE THIS MANUAL.
Intended Applications
For use on fully charged lead-acid and AGM (Absorbed Glass Mat) type batteries only.
TO PREVENT BATTERY DAMAGE:
Do not use on GEL batteries.
Note: Check battery voltage with a multimeter before use.
The Battery MUST be fully charged to at least 12 Volts.
The Float Charger prevents self-discharge of the battery, while maintaining and extending
the life of rechargeable 12 volt lead-acid batteries. It maintains a battery charge for batteries
rated from 5 – 125 Ah (amp-hours), by providing a 13.2 VDC maximum output. Other types of
chargers provide a strong, rapid charge but tend to boil out liquids and decay electrodes.
