Overview

The aviation battery specific line of BatteryMINDer® battery chargers-maintainers-desulfators are the most advanced ever produced. In addition to charging and maintaining the indicated 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 CEC2-AA series they feature advancements in easy to understand battery analysis and condition not previously available in any other single model. Their high efficiency design, controlled by industrially-rated microprocessors, allow continuous operation (24 hrs./day) for less than $0.43/mont*. Temperature sensors prevents over/under charging from freezing to 130-F.

Features

  • 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)
  • 12 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.

Product seems to be working as offered. Unit is small, convenient and easy to use. The charge is working in hangar attached to a solar panel with battery. All great for now.

Great product. Batteries for my 1980 Cessna 180 are $1000+. This maintenance/charger keeps my battery at its peak power and helps it last for 2-3 longer than without it. A must-have if you can’t fly regularly.

Please note, Aircraft Spruce Canada's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce Canada assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: My mechanic or aircraft manufacturer claims installing the BM-AIK2A airframe interface accessory is a major alteration and would require an STC. Is that true?

Per the manufacturer: No, the FAA is the sole governing authority on modifications of certified aircraft. The BM-AIK kits have been reviewed by FAA and industry personnel, who agree that its installation does not rise to the level of a major alteration to the aircraft. Only a major alteration, as defined by federal aviation regulations, requires an STC, or FSDO field approval, and filing an FAA form 337 to document the change. It is not the decision of the airframe manufacturer, or type certificate holder. Because it is NOT a major alteration, it is a MINOR alteration, which is within the authority of the installing mechanic to sign off with a simple maintenance log entry.

Q: My battery is covered bolted down and back in the fuselage. Can I clip the charger to the 28v external supply port rather than direct to the battery?

Yes, but you will need a universal jump plug either Piper/Cessna style plug.

Q: Does this battery minder work on gel-cell batteries?

No, this is designed for Gill batteries that are AGM.

Q: Will this charger, MFR Model# 244CEC2-AA-S2, work on a Gill GE-50C?

Yes, the BatteryMINDer 244CEC2-AA-S2 is the correct model for Gill batteries, including the LT Series.
