VDC Electronics 12248 BatteryMINDer Charger Overview

12 Volt multi amperage select smart charger (2A, 4A, 8A), maintainer and desulfator for all types of lead acid batteries.

The BatteryMINDER® 12248 is an ideal choice for handling 12 Volt battery charging requirements. The FCC-certified 3-stage smart microprocessor-controlled BatteryMINDer® has a built-in desulfator that automatically dissolves harmful power-robbing, life-shortening sulfation using safe high-frequency "sweep pulse" technology. Safely charges any size/type or brand of 12V lead-acid battery, Works with all sizes, types and brands of 12V lead-acid batteries (Including but not limited to: flooded (filler cap / maintenance-free / VRLA / SLA), gel, AGM (Optima / Odyssey / etc.), starter, deep cycle and hybrid) — with no overcharging. Safely charges 70% to 200% faster than other conventional constant voltage chargers. Maximizes cycle life and performance of all three types of lead-acid storage batteries regardless of size, type or brand. For aviation batteries please see the aviation line as this charger is not for use with 12V aircraft battery.

BatteryMINDer 12248 Charger Features:

  • Guaranteed to never overcharge, regardless of how long connected.
  • Ambient Temperature compensation ensures proper charge in hot or cold environments.

FAQs About This Product

Ask a Question

  • What is a Desulfator?

    A desulfator is a device that when attached to a lead acid battery will clean the internal plates. They remove hardened sulfate crystals that have built up as a result of sulfation (see: What is Sulfation?). True desulfators use a pulse frequency to desolve these crystals vs. the less effective voltage pulse

    Rate This Answer:

  • What Is Sulfation?

    Sulfation is the buildup of lead sulfate (PbSo4) crystals on your battery plates.

    Contrast image of built up of sulfate crystals on a battery.All lead acid batteries will suffer from the effects of sulfation. It is the unwanted byproduct of the natural double sulfate chemical reaction that generates electricity within the battery. When a battery is in use, the active material on your battery’s plates, lead and lead dioxide, react with the electrolyte or sulfuric acid (H2SO4) to generate electricity. During this process a thin layer of non-crystalline solid lead sulfate is deposited on the plates.

    During charging, this sulfate deposit is supposed to be converted back to lead dioxide and sulfuric acid restoring the battery back to its pre-discharged state. However, the process is not perfect. Incomplete charging or prolonged time left in a discharged state will convert the amorphous (non-crystalline) lead sulfate into a hardened crystalized form diminishing the ability of the battery to reach full charge.

    Rate This Answer:

  • Can this be used on a motorhome with 4, 6 volt batteries. Two are in series to make 12 volts and then the two systems are paralled for more amperage.
    Yes you could use this charger to maintain and desulfate your 6 volt batteries tied together in a 12V parallel series configuration.
