Note:
These BatteryMINDers are the S1 version. Similar to the current S2 version, but without the automatic recognition mechanism. Still made for aviation use, but requires an extra button press.

The BatteryMINDer® is a 3-mode charger/maintainer/conditioner that extends performance and life of aviation batteries—without overcharging. Ideal for keeping your sealed or wet-cell aircraft battery in optimum condition. If your flying is limited, especially during the winter, a BatteryMINDer will keep your airplane's battery charged up and ready to operate with peak performance.

• Effective and safe for nearly all aircraft batteries, including sealed AGM, gel and flooded wet-cell
• Simple installation means you plug it in and walk away--even restarts automatically after a power failure
• Patented pulse circuitry dissolves sulphate buildup that causes batteries to fail prematurely
• Guaranteed never to overcharge, regardless of time or temperature
• Spark-proof, short circuit, reverse polarity and temperature compensation
• Comes complete with battery clips and fused ring terminal assembly for easy connect-disconnect

Don't rely on a cheap car battery charger--only the BatteryMINDer is specifically made for use with aviation batteries. Features a weatherproof enclosure and a five year warranty. Measures 5 1/2” x 5 1/2” x 2 1/4”; weighs 2.2 lbs.
