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.

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