If you find yourself with a dead battery in your car and have access to a battery charger you are only some time away from being on the road again. Whether you are using a small car charger known as a trickle charger or a larger unit on wheels, you can charge your battery effectively. There are safety concerns though. Be sure to check the warnings
1、Locate the battery or remote charging point by consulting the owner’s manual. You can also open the hood to find the battery. The laptop battery may be under a seat, in which case a charging point may be provided under the hood.
2、Remove any plastic covers that may be protecting the positive and negative posts of the battery. Just push the covers to the side as they are usually pliable. Note the location of positive and negative terminals signified by a plus and a minus sign respectively.
3、Locate the laptop car charger so that its cables will reach the battery. Make sure your charger will reach an electrical outlet. Add an extension cord if needed.
4、Place the clamps of the charger on the battery making sure that the red handled clamp goes to the positive battery post and the black handled clamp goes to the negative laptop batteries post. If you are not sure, trace the cable attached to the clamp back to the charger and look for a positive or negative designation. If you are still not sure, stop and seek professional advice.
5、Plug the charger in, making sure that the selection switch is set to off.
6、Select the appropriate voltage and or rate (almost all cars have a 12 volt system). If time permits choose the slower rate and plan on charging the battery for two hours. This selection will turn the charger on. If the charger has a timer, set it.
7、After charging the battery, unplug the charger, disconnect the charger’s cables and start the car.
