BatteryMINDer 2012-AGM is a SmarTECHnology microprocessor controlled charger/maintainer/desulfator for High-Performance AGM Sealed Batteries such as Odyssey, Hawker and other AGM batteries that contain Pure Lead Thin Plate Technology (PLT). Plug 'n Run feature means "no buttons to push." It is designed with 7-stages and is fully automatic. This charger actively monitors your battery's voltage, amperage acceptance and temperature at all times. Will not overcharge, regardless of how long connected. Temperature compensation ensures proper charge in hot or cold environments. Installed ambient temperature sensor for 0°F–130°F operating range ensures the battery will never be overcharged or undercharged regardless of temperature extremes. Optional "at the battery" sensor is also available for greater accuracy when battery and charger are not in same ambient temperature environment. Diagnostic LED indicators for power, polarity reversal, battery weak, load, bad cell, testing, desulfating, temperature compensation, charging stage and charge level. Maximizes battery life and capacity, reconditions weak batteries. Plug 'n Run operation-no buttons to push.
