BatteryMINDer Model 2012-AGM: 12Volt-2 Amp Battery Charger Maintainer/Desulfator for Odyssey, Optima and AGM Lead-Acid Batteries - Designed for Cars, Trucks, Motorcycles, ATV, Boat, RV, etc. EXTENDED BATTERY LIFE - Automatic full time desulfator reverses sulfation (a buildup of lead sulfate crystals) the primary cause of early battery failure by using a patented range of high frequency pulse desulfation (not high voltage) to safely remove sulfation and recondition weak 12V AGM batteries. Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition. Extending battery life up to four times when compared to new batteries not being properly AMBIENT TEMPERATURE SENSOR  Installed temperature compensation precisely adjusts battery voltage based on temperature sensor readings. This ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. Reverse polarity, short-circuit and over temperature protection. SIX BATTERIES AT A TIME - Maintains up to six 12V AGM batteries (of the same type) at a time when connected in parallel. Requires the use of Y-Connectors 210AY (sold separately). Intended for High-Performance AGM Sealed Batteries such as Odyssey, Hawker and other AGM batteries that contain Pure Lead Thin Plate Technology (PLT). Worldwide 100-240 VAC 50/60 Hz input. INCLUDES  Included in the box is Model 2012-AGM, an installed Ambient Temperature Sensor, 2 Battery Clip Cord with Quick Connector, 2 Fused Ring Terminal, and a 6 AC and 6 DC cord. FCC CERTIFIED - Certified by the California Energy Commission as meeting the current efficiency standards which means it meets strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy. Will not overcharge, regardless of how long connected. Temperature compensation ensures proper charge in hot or cold environments. Installed ambient temperature sensor for 0F130F operating range ensures the battery will never be overcharged or undercharged regardless of temperature extremes. Optional &#034;at the battery&#034; 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 &#039;n Run operation-no buttons to push.
