BatteryMINDer® 2012 is a SmarTECHnology™ microprocessor controlled charger/maintainer/desulfator. It is designed with 7–stages and is fully automatic. Plug ‘n Run feature means “no buttons to push.” Features easily understood diagnostic LED indicators that display the battery's condition and actual state–of–charge profile. This charger actively monitors your battery's voltage, amperage acceptance and temperature at all times. Working through a series of charging and diagnostics stages, the internal program adjusts its output several times a second based on sensor reading to quickly and correctly charge your battery.

When used as a maintainer, the BatteryMINDer® is guaranteed to maximize your battery's life and storage capacity. The temperature compensated long–term maintenance stage will add years of service. Patented full–time high frequency pulse desulfation (NOT high voltage) prevents battery sulfation on new batteries or eliminates in older batteries, the #1 cause of early battery failure. Unit can maintain up to six 12 Volt batteries at one time when connected in parallel by using SmarTechnology™ Y–Connectors 210AY or customer supplied 18–Gauge insulated wire.
