About this item

  • EIGHT BATTERIES AT A TIME - Maintains up to eight batteries at a time when connected in parallel. Requires the use of Y-Connectors 210AY (sold separately). Ideal for winterizing Cars, Trucks, Motorcycles, ATV, Boat, RV, etc. The 90-140 VAC 47-63 Hz input allows for worldwide use. Settings for all sealed, wet (filler cap), maintenance-free, AGM, deep cycle, RV, marine, PLT and Odyssey brand lead-acid based batteries.
  • AMBIENT TEMPERATURE SENSOR– 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.
  • 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 frequencies to safely remove sulfation and recondition weak 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 maintained.
  • 2/4/8 AMP – Use the 2 Amp setting for batteries that are charged and in good shape. Use the 4 Amp setting when charging more than one battery or a large deep cycle battery. The 8 Amp setting is best for wet, AGM, Sealed, and Lithium batteries. Use the Odyssey selection for all Odyssey batteries.
  • 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. High efficiency and low power consumption. 5 Year Manufacturer Warranty Included

    Best AGM charger I've found.
    5 Stars
    Best AGM charger I've found.
    I've purchased a whole slew of chargers on Amazon trying to get one that would fully charge my 12V 190AH AGM batteries so I can get them to the same voltage to connect them in a 48V bank! So far, I had one charger overcharging them, one 4-bank charger (in the picture) that would undercharge and not charge them to the same voltage, and another one that wouldn't charge them all the way.This BatteryMINDer unit fully charges the batteries to the same voltage. I wanted a 4-battety charger, so I could charge each bank at once, but I'm settling for this single battery charger since it has been the only one that actually works!Very happy with the product.
