Introduction and Background Information
The Model DS24041-AA-S5 is a special configuration of the BatteryMINDer 3-stage battery charger
specifically calibrated for lead-acid aircraft batteries only. Audio Authority, in collaboration with VDC
Electronics, has incorporated this award-winning technology as an option into the 2800 Series Ground
Power Units for general aviation aircraft.
It is designed to gently charge aircraft batteries as completely as possible and then continuously maintain
them at their maximum charge. While in this maintenance or float mode, the BatteryMINDer employs
patented technology to modulate high-frequency pulses to the battery to break up and dissolve the lead
sulfates that naturally form on the battery plates. This sulfation process reduces battery capacity and is
made worse by extended periods of inactivity, high heat, and poor maintenance. Aviation batteries must
maintain a minimum of 80 or 85% of their rated capacity to be airworthy, or legal for flight.
The BatteryMINDer’s continuous desulfation can actually reverse the battery aging process, which will
restore capacity and significantly extend the useful life of aircraft batteries. The BatteryMINDer is
designed and intended for full-time continuous-duty use. It is recommended that it be kept connected
whenever the aircraft is in hangar storage to maintain and condition the battery.
To prevent over or undercharging, the aviation BatteryMINDer automatically adjusts its output in
response to an ambient temperature sensor, incorporated into the special output cable.
A Model BM-AIK1 Airframe Interface Kit is supplied and contains the aviation-grade parts and
instructions necessary for a FAA-licensed mechanic to install a simple wiring harness to access the
battery on a certified aircraft. This harness provides a mating polarized plug for quick connect and
disconnect of the BatteryMINDer from the aircraft. An airframe log entry is all that is required to
document this minor alteration and return the aircraft to service.
The BatteryMINDer’s “plug-n-run” design requires no input from the operator, or if line power is lost.
Make ust one connection to the aircraft, turn it on, and leave. Operation is completely automatic.
Faithful use of the BatteryMINDer will provide maximum starting power every time, important for all
aircraft, but especially for turbine starts.
IMPORTANT SAFETY PRECAUTIONS
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR PERSONAL INJURY, OBSERVE
THE FOLLOWING:
1)
Do not expose charger to moisture or precipitation. It is designed to operate ONLY INDOORS.
2)
USE of any attachment not specifically recommended by the battery charger manufacturer for use
with this exact model of charger may result in additional risk of fire & electric shock or personal
injury.
3)
Do not use charger if it receives a sharp blow, is dropped, or damaged.
4)
Charger contains no serviceable parts. If it fails for any reason, return it to Audio Authority Corp for
repair or replacement.
5)
WARNING - RISK OF EXPLOSIVE GASES
. Whenever you work near a lead-acid battery, there
are inherent risks and dangers that must be managed and mitigated. Batteries generate explosive gases
during normal operation, therefore it is of utmost importance that the operator be familiar with, refer
to, and follow the instructions in this manual exactly
to reduce the risk of battery explosion.
Additionally, follow the instructions published by the battery and aircraft manufacturer. Review and
abide by all safety & cautionary product markings.
