This Universal Charger handles them all! The Aviation BatteryMINDer was rated #1 by Aviation Consumer!

Using the latest in microprocessor controlled algorithms, coupled with several U.S patented desulphation-recovery circuits, the BatterMINDer? model 12248-AA-S2 Charger/Maintainer/Desulphator-Conditioner has been designed to fully charge, maintain and condition all type/size/brands of 12-Volt lead acide type batteries. With three (3) charging rates (2/4/8 Amps) and selectable voltage settings, the unit's output will match any known battery manufacturer's recommended charging-maintenance profiles for sealed-valve regulated, flooded, absorbed glass mat (agm), as well as free electrolyte deep cycle, starter and dual purpose types. It is also factory/dealer adjustable for specialty gel or environmentally "unfriendly" applications.

Model 12248-AA-S2 allows batteries as small as 14 AH to 150 AH to be safely charged 70% faster than conventional constant voltage type chargers without fear of under or overcharge. U.S. patented "sweep-pulse" desulphation safely dissolves both old, as well as newly formed sulphation, still considered to be the #1 cause of early battery failure. Built-in tester allows for easy assessment of battery condition, state of charge and detects the existence of sulphation.

Model 12248-AA-S2 uses a watertight enclosure with built-in mounting tabs and non-slip pads allowing it to be used as a dedicated charger for multi-use in home or shop. The unit comes complete with two (2) types of battery attachments and an optional 12-volt power plug for indirect-easy access connection to the battery. Parallel maintenance charging with simultaneous desulphation for up to six (6) batteries is also possible.

Temperature sensor is included at no additional charge!

Additional Features:

• 3 stage (constant current bulk, constant voltage absorption, pulse width modulated float).
• Full Time randon sweep desulphation.*
• Short circuit and reverse polarity protected.
• Polarity reversal indicator.
• Auto-reset thermal breaker (protects both battery and charger under abnormal conditions such as a shorted cell and/or excessively high temperatures).
• User selectable outputs (allows for optimum matching of batter and charge rate).
• Factory adjustable voltage settings (for special applications).
• Spark-proof.
• Manual override allows for maintenance/desulphation-only storage mode.
• Optima/AGM/Lower Temperature Mode push buttion selection.
• Rejects a damaged or open cell (shorted) battery.
• Watertight enclosure with conformal coated protected circuitry.
• Built-in battery condition indicators (detects and displays charge level, retention and existance of sulphation).
• Automatic temperature compensation.
