Sometimes, it&rsquo;s not even the primary culprit behind battery issues.<\/p>\n\n\n\n<p>In some cases, cold weather aggravates earlier issues that drain the battery. Therefore, it&rsquo;s vital to identify the exact cause of the problem to prevent it from reappearing down the line.<\/p>\n\n\n\n<p>Freezing weather can drain a car battery anywhere between 30% and 60%. This is usually because the electrochemical reaction has been slowed down because of the drop in temperature. As a result, the battery gets weaker.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Does Cold Weather Drain Car Batteries?<\/h2>\n\n\n\n<p>So, what drains a car battery in cold weather? Here are the leading reasons:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lower Car Battery Capacity<\/h3>\n\n\n\n<p>When you start your car, the battery supplies enough current to get the starter going and crank the engine. It propels charged particles through a medium, triggering a chemical reaction that releases power stored in the device.<\/p>\n\n\n\n<p>Unfortunately, cold weather slows the movement rate of the charged particles in car batteries. A cold battery has a lower capacity than expected, which can interfere with starting and cranking the engine.<\/p>\n\n\n\n<p>Older batteries are even more vulnerable to the detrimental effects of cold temperatures and sometimes cannot generate enough energy to start and crank the car when it&rsquo;s cold out there.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-data443-irp-shortcode irp-shortcode\"><div style=\"clear:both; margin-top:0em; margin-bottom:1em;\"><a href=\"https:\/\/www.carparts.com\/blog\/the-starting-system\/\" target=\"_self\" rel=\"dofollow\" class=\"ua96bd401530c8de8ca954f9899780a4d\"><style> .ua96bd401530c8de8ca954f9899780a4d { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; text-decoration:none; } .ua96bd401530c8de8ca954f9899780a4d:active, .ua96bd401530c8de8ca954f9899780a4d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .ua96bd401530c8de8ca954f9899780a4d { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .ua96bd401530c8de8ca954f9899780a4d .ctaText { font-weight:bold; color:#464646; text-decoration:none; font-size: 16px; } .ua96bd401530c8de8ca954f9899780a4d .postTitle { color:#000000; text-decoration: underline!important; font-size: 16px; } .ua96bd401530c8de8ca954f9899780a4d:hover .postTitle { text-decoration: underline!important; } <\/style><div style=\"padding-left:1em; padding-right:1em;\"><span class=\"ctaText\">See also<\/span>&nbsp; <span class=\"postTitle\">The Starting System<\/span><\/div><\/a><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Reduced Charge Rate<\/h3>\n\n\n\n<p>While the battery initially powers the ignition system and essential accessories, it makes way for the alternator once the engine hits its stride. The <a href=\"https:\/\/www.carparts.com\/alternator\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"alternator\">alternator<\/a> charges the battery, replenishing the energy expended during the engine start-up sequence. Nothing recharges your car battery better or faster than the alternator.<\/p>\n\n\n\n<p>Cold weather not only reduces the overall capacity of the battery, it also slows down its charging rate. The alternator needs more time to top off the battery, so if it doesn&rsquo;t get enough charging time, it can become depleted.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Thickened Engine Oil<\/h3>\n\n\n\n<p>The car battery isn&rsquo;t the only part affected by cold weather. The engine can also develop problems when it gets cold. In turn, engine issues can affect the battery.<\/p>\n\n\n\n<p>Engine oil, which greases the engine&rsquo;s internal parts, becomes thicker and more viscous at low temperatures. Thickened oil flows more slowly, which increases the power and work required to turn over the engine.<\/p>\n\n\n\n<p>So, how does this affect the battery? The battery supplies the power for cranking the engine. It must overcome the increased resistance by delivering more power, which drains it faster.<\/p>\n\n\n\n<p>It gets worse. Cold weather also reduces the battery&rsquo;s capacity to release power. If the underperforming battery cannot deliver enough power to meet the increased demand of an engine with thickened oil, your car might not start.<\/p>\n\n\n<style>.kadence-column99631_72e284-03 >

You run the heater to stay warm inside your car, the defroster to eliminate frost on the windows, and the windshield wipers to remove snow from the glass.<\/p>\n\n\n\n<p>The car battery provides the power to operate these parts if the engine isn&rsquo;t running. While the alternator takes over the task once you successfully start the engine, the battery will supply additional power if the generator cannot produce enough energy to meet the heavy demand.<\/p>\n\n\n\n<p>As long as the battery keeps releasing power instead of charging up, it cannot replenish itself. Eventually, it might become discharged, leaving you with a dead battery that cannot start your car.<\/p>\n\n\n\n<p>Furthermore, the battery might suffer parasitic drain, an issue where a part keeps drawing power from it even when the car isn&rsquo;t running. It can happen if you leave something operating or a part develops an issue with its circuit, leading to it continuously pulling power.<\/p>\n\n\n\n<p>Between all the features you&rsquo;re running when it&rsquo;s cold, plus any parasitic drain, you might drain the battery faster than you realize.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How to Keep the Car Battery From Dying In Cold Weather<\/h2>\n\n\n\n<p>Now that you know how cold weather drains car batteries, what can you do to prevent it? Here are some tips and tricks to protect the battery from getting drained when it&rsquo;s cold out there:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Get a Battery With a High Cold Cranking Amps Rating<\/h3>\n\n\n\n<p>If you often drive in cold weather, get a battery with a high cold cranking amps (CCA) rating. CCA is a rating system that determines the battery&rsquo;s ability to start and crank the engine at 0&deg;F (-18&deg;C). The higher the rating, the more amps the battery produces during cold temperatures.<\/p>\n\n\n\n<p>A battery with a high CCA rating will continue operating effectively no matter how cold it gets.<\/p>\n\n\n\n<div class=\"wp-block-data443-irp-shortcode irp-shortcode\"><div style=\"clear:both; margin-top:0em; margin-bottom:1em;\"><a href=\"https:\/\/www.carparts.com\/blog\/underhood-checks\/\" target=\"_self\" rel=\"dofollow\" class=\"ued1219d695a96806dc14c25a3ed9ffb6\"><style> .ued1219d695a96806dc14c25a3ed9ffb6 { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; text-decoration:none; } .ued1219d695a96806dc14c25a3ed9ffb6:active, .ued1219d695a96806dc14c25a3ed9ffb6:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .ued1219d695a96806dc14c25a3ed9ffb6 { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .ued1219d695a96806dc14c25a3ed9ffb6 .ctaText { font-weight:bold; color:#464646; text-decoration:none; font-size: 16px; } .ued1219d695a96806dc14c25a3ed9ffb6 .postTitle { color:#000000; text-decoration: underline!important; font-size: 16px; } .ued1219d695a96806dc14c25a3ed9ffb6:hover .postTitle { text-decoration: underline!important; } <\/style><div style=\"padding-left:1em; padding-right:1em;\"><span class=\"ctaText\">See also<\/span>&nbsp; <span class=\"postTitle\">Underhood Checks<\/span><\/div><\/a><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Park in a Safe Place and Shut Down the Security System<\/h3>\n\n\n\n<p>Does your car have an anti-theft system? While the security system provides peace of mind, it also drains the car battery, which can prove problematic when it gets cold outside.<\/p>\n\n\n\n<p>Park your car in your garage or another safe space with external security. You can turn the security system off to reduce the drain on the battery without leaving your vehicle vulnerable to thieves.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Disconnect the Negative Battery Terminal<\/h3>\n\n\n\n<p>As long as the car remains connected to the negative battery end, it will draw power from the battery. Look for the connector with a minus sign or a black color. Disconnect and insulate it. When you need to start your vehicle, reattach the connector.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Invest In a Thermal Battery Blanket<\/h3>\n\n\n\n<p>Get a thermal blanket to serve as <a href=\"https:\/\/www.carparts.com\/blog\/what-is-a-battery-isolator-how-does-it-work\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"insulation for the car battery\">insulation for the car battery<\/a>. Made of material that captures and keeps heat, the blanket also has a heating element that runs on an external power supply. You can spread the thermal blanket over the battery to keep it warm during cold weather.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use an Engine Block Heater<\/h3>\n\n\n\n<p>Alternatively, you can get an <a href=\"https:\/\/www.carparts.com\/blog\/a-helpful-guide-to-engine-block-heaters\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"engine block heater\">engine block heater<\/a> that warms the engine block and the battery. Not only will the heater protect the battery from cold-related lost capacity, it will also prevent the engine oil from thickening because of the cold weather.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Put Your Jump Starters to Good Use<\/h3>\n\n\n\n<p>Sometimes, the car battery can die without warning during cold weather. You can <a href=\"https:\/\/www.carparts.com\/blog\/jump-starting-basics-how-long-will-it-take-to-get-your-car-up-and-running\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"jump-start\">jump-start<\/a> it to get the engine running, allowing you to drive to where you can replace the discharged battery,<\/p>\n\n\n\n<p>Cold weather can be a literal drain on the car battery. However, you can prevent its negative effects with some easy steps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Warm Up the Engine Regularly<\/h3>\n\n\n\n<p>As a car owner, it can be tempting to stay indoors during the winter. And while you think you car will be fine as it is under freezing temperatures, the battery could be suffering without you knowing.<\/p>\n\n\n\n<p>According to the American Automobile Association (AAA), car owners should warm up their vehicles for at least 30 minutes or more at least once a week.<\/p>\n\n\n\n<p>Regularly warming up the engine can help maintain the battery&rsquo;s service life, ensure that seals are properly lubricated, and prevent contaminants from building up in the engine oil.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 5<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Cold weather affects your car as much as it affects you.
