Jump start car with laptop charger
Using a Laptop Charger to Start a Car? The title says it all. The steps are provided below. Things are not as easy as they seem, because a laptop battery is essentially a lithium polymer one and can be quite a capricious component. Here is how you can carry this process out effectively not to mention safely. Essentially an item that can be ‘found around the house’, laptop batteries if used wrongly can irreparably damage your car battery. Know that it is a risky fire-hazard procedure that could harm you in the process; stop grinning, this is not a thrill-moment. Here is a list of all you will need to put this together:
Get yourself a 14-volt power suppy that can handle 0.5 A (amps) maximum current. This is you playing it safe and maintaining the battery’s charging rate at a goodly 13.2 – 14.4 volts.
Charging will take all of two or so hours. However, there is a high chance that the engine will come on but lacks sufficient juice to start. You can charge the battery overnight (about 7-8 hours) but there is a faster way over this obstacle.
After only half an hour of this, give the car battery another try. It is wiser to discharge the battery than over-charge it. Take the lighter out of its plug and turn the ignition. There is a high chance your car will roar to life. Keep it running for five minutes. Side Note 1: The cigarette lighter is generally fused at 10 A, so it is best to keep the current running below 4 A. Side Note 2: When dealing with a 19 V power supply that can work with 4 A (and you have a 12 V car battery), the minimum needed resistance R = voltage supply – 12 / limit of current. The equation goes like this… (19-12) / 4 = 1.75 Ohm. Side Note 3: All wires to be used need to have good connections between them. You do not want things over-heating and becoming a fire hazard. Sandpaper will help you remove dirt or oxidation at the connections. Side Note 4: Circuits should never directly be linked to the car battery. A fuse should be present between them. ConclusionThis entire method need only apply to help get the engine going. Drive the car and let its own alternator do the rest of the charging. If you see the battery exceeding 14.4 volts, cease charging altogether. This could happen with old or damaged batteries. If you are still unsure, best call a professional or jumpstart your car using the battery power from another vehicle.
