 Charger - Maintainer - Desulfator

These chargers-maintainers-desulfators are designed for all size and type 24-Volt Concorde® Aviation Batteries. If you want the longest possible life and performance from your batteries there is no other product better at doing just this and BatteryMINDer® Guarantees it! In addition to charging and maintaining all 24V Concorde® sealed or wet cell (filler caps) aviation batteries users can now determine the level of charge remaining in their battery, and if weak and in need of replacement, before going bad.

Units test for weak/dead cells and will recover weak or severely discharged batteries that other chargers would reject. Known as the CEC1-AA series they feature advancements in easy-to-understand battery analysis and conditions not previously available in any other single model. Their high-efficiency design, controlled by industrially-rated microprocessors, allows continuous operation (24 hrs./day) for less than $0.43/month*. Temperature sensors prevent over/under charging from freezing to 130-F.


BatteryMINDER Charging Stages

  • Guaranteed to never overcharge/undercharge. (33°F to 130°F)

  • Tested and endorsed by leading Battery makers.

  • 100% Full - Time U.S. Patented Pulse-type Desulfation keeps battery free of sulfate or dissolves sulfate completely in older batteries.

  • Detects and rejects batteries with bad cells. Terminate charge to prevent out-gassing.

  • Maximize battery life and capacity, recovers weak batteries.

  • Diagnoses battery’s condition / state-of-charge.

  • Recovers weak or deeply discharged batteries: including but not limited to flooded filler cap, maintenance-free, valve regulated lead-acid (VRLA), sealed lead-acid (SLA), starter, deep cycle and hybrid.

  • Maintain up to 2 batteries at a time. (requires BatteryMINDer® Y-Connector Accessory 210-AY)

  • Auto-Restart after power failure.

  • Bad cell detection with auto-shutdown.

  • Includes Short circuit, spark, reverse polarity protection, thermal runaway protection, automatic D/C disconnect on A/C failure and quick-connect/disconnect fused alligator clip assembly.

  • Very high efficiency. California CEC Approved. Certified to California Energy Commission Standards.

  • Automatically detects input AC power.

  • ECO-mode with hi-efficiency / low power consumption. This allows the unit to always remain connected to AC while consuming very low level of electricity.

  • Ambient temperature compensation. Built-in temperature sensor automatically adjusts charge rate to ensure full-charge. (as low as 0°F or as high as 130°F)

  • 2 LED indicators show state-of-charge and important status mode / battery condition.

  • Rugged, vibration-resistant construction.

  • Never connect two or more batteries together before fully charging each and checking their condition. Failure to fully charge each battery and check their condition can result in a serious safety hazard.
