The Purkeys Direct™ system improves the charging of liftgate
batteries by utilizing a DC/DC Converter to boost the voltage for
optimal charging. The boost in voltage overcomes the normal
voltage drop caused by the extended distance between the
liftgate batteries and the vehicle charging system. Also, in cold
temperatures batteries require increased charging voltages
to maintain a high state of charge. The DC/DC Converter in
the Direct system compensates for temperature as well as for
voltage drop and provides the best voltage to the remotely
located liftgate batteries. The result is well-charged liftgate
batteries that will last longer and have ample power for liftgate
operation.
The Direct system is automatic and has easy to interpret LED
indicators to assure drivers and technicians of proper system
function. The Direct Controller increases the time that the DC/
DC Converter can charge the liftgate batteries by monitoring the
source power and “extending” the liftgate battery charge time to
take full advantage of the available power, without compromising
the source batteries’ ability to crank the engine. Simply put,
the Direct system provides opportunity charging for the liftgate
batteries that is essential in low mileage, high frequency liftgate
operation applications. The LED indicators clearly show the
status of the source as well as the status of the liftgate batteries.
A quick glance at the Direct Controller assures the driver that
the liftgate batteries are ready to go, or alerts the driver that the
batteries need maintenance.
NOTE: Our liftgate charging systems are designed to work with
flooded cell and AGM batteries. If you are using this system to
charge any other type of battery, please contact us at 479-419-
