What few drivers know."},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">During the colder months, it&#8217;s much more common to encounter a dead battery. When a car won&#8217;t start, many drivers resort to jump-starting it with cables to get power from another vehicle. However, a very common practice can end up causing costly damage: trying to jump-start another car while the vehicle providing the jump start is still running.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why do batteries fail more often in winter?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Low temperatures directly affect battery performance. When it&#8217;s cold, the capacity to store and deliver energy decreases considerably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, the engine needs more effort to start in cold conditions, which places a greater electrical demand on it. If the battery is already showing signs of wear, it may not have enough power to start the vehicle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to use jumper cables correctly<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Jump-starting remains an effective solution when done correctly. The key is to follow the proper procedure to avoid damaging the electrical systems of both vehicles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Materials needed<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Good quality jumper cables.<\/li>\n\n\n\n<li>Firm and secure clamps.<\/li>\n\n\n\n<li>Copper conductors of sufficient thickness to withstand power transfer.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Connect the cables correctly<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before making any connection, make sure both vehicles are turned off.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Connect the positive (+) cable to the positive terminal of the discharged battery.<\/li>\n\n\n\n<li>Connect the other end to the positive terminal of the battery that will provide power.<\/li>\n\n\n\n<li>Connect the negative (-) cable to the negative terminal of the auxiliary battery.<\/li>\n\n\n\n<li>Place the other end of the negative cable on a metal part of the broken-down vehicle, away from the battery.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Partially recharge the discharged battery<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Start the vehicle that is providing power and let it run for 10 to 15 minutes. This will allow the discharged battery to receive a sufficient initial charge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Turn off the auxiliary vehicle<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once the partial charging is complete, turn off the engine of the vehicle that is assisting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This step is important because it reduces the risk of overloads that could affect the alternator or sensitive electronic components.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Start the broken-down vehicle<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Try starting the vehicle with a dead battery. If it starts successfully, leave the engine running for several minutes to allow it to continue charging.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Remove the cables<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Disconnect the cables in the reverse order of installation to avoid sparks or short circuits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mistakes you should never make<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Keep the vehicle that provides power running.<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is one of the most common mistakes. Although many people believe it helps transmit more power, it can cause voltage spikes that damage the alternator or electronic components of the auxiliary vehicle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reverse the poles<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Connecting the positive and negative terminals can cause serious short circuits, damage to electronics, and even a risk of fire.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using poor quality cables<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cables that are too thin or have poor connections hinder energy transfer and increase the risk of overheating.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to prevent future battery drain<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Check its status periodically<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A worn-out battery often shows signs before failing completely. If you notice slow starts or electrical problems, consider having it checked.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Protect the vehicle from the cold<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Whenever possible, park in a garage or use heat shields to reduce the impact of low temperatures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reduce unnecessary electricity consumption<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before starting the engine, turn off lights, radio, air conditioning and other accessories that may require additional power.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Keep the terminals clean<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Corrosion on the terminals can impede current flow and reduce battery performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tips and recommendations<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Always carry good quality jumper cables in your vehicle.<\/li>\n\n\n\n<li>Check the age of the battery; most have a lifespan of between 3 and 5 years.<\/li>\n\n\n\n<li>If your battery frequently drains, consult a mechanic to check the alternator and charging system.<\/li>\n\n\n\n<li>Avoid leaving lights or accessories on when the engine is off.<\/li>\n\n\n\n<li>Make long enough journeys to allow the battery to recharge properly.<\/li>\n\n\n\n<li>If you have any questions, consult your vehicle manufacturer&#8217;s manual, as some modern models have specific procedures.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Jump-starting a vehicle can get you out of a jam, but doing it incorrectly can cause costly damage. By following the proper procedure and taking some basic precautions, you can help other drivers while also protecting your car&#8217;s electrical system.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>During the colder months, it&#8217;s much more common to encounter a dead battery.
