Charging batteries in the Field

If you are in the field, you’re running low on batteries and your project is not completed yet, you can charge your batteries in the field.

The voltage that is needed for your charger is between 11V and 18 V DC (Direct Current).

The usual voltage provided from the vehicle is 12 V.

Where and how should I connect the cables?

First, connect your cables from your car battery to the WingtraCharger. BE CAREFUL! Connect the positive (+) pole from a car battery to the correct clamp. Red clamp connects to the positive (+) pole, and the black clamp connects to the negative (-) pole.

While charging, make sure that all of the other devices in the vehicle are turned off, radio, wipers, etc.

Make sure that the cables are close enough to the Wingtra Charger so that they cannot disconnect from the vehicle battery during the charging.

Connect the wires from your car battery to your Wingtra Charger as shown in the pictures below.


Turn on your vehicle, and don’t turn it off until your batteries are fully charged.

Make sure that your charger and batteries are on a flat surface so that they don’t slip during the charging and cause an undesired contact between the wires that can cause a short circuit.

To avoid overheating of your vehicle and your Wingtra Charger, please avoid direct sunlight and charge your batteries in the shade.
