I have new BatteryMINDer chargers that are 10% off through August 31st of this month. They are regularly $270.95 but are discounted to $243.86. The 10% off includes accessories but does not apply to the airframe interface kit ($85) option.
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/month*. Temperature sensors prevents over/under charging from freezing to 130-F.
