The chart below shows the need to regulate the output voltage of the
charger to ensure against over or under charging your battery over a
wide range of temperatures. Using your Ambient Temperature Sensor
(
ATS-1) will accomplish this better than any other known method.
*Values shown are based on information supplied by Concorde Battery Co., effective
May 15, 2012. Values for batteries manufactured by other aviation battery companies
are believed to comparable. We strongly recommend checking with the appropriate
dealer or battery manufacturer to be certain.
