There are some defects when it is installed on storage battery of electric car, like most people do.
First, the charging indicator will continue give out electricity when the charger works.(the amount is too little to be concerned)
Second, It is easy to be oxidized after long time powering on.
So, it is recommanded that connect red line of the charger with positive output power line(black one as usual), and connect the black line of the charger with passitive power line(green one as usual). After doing that, the power will be on only when the key works. Otherwise, a control switch is recommanded if you still want install it on the storage battery.
