But if you don\u2019t use your car battery for a long enough time, it can start failing. We dig into what went down and why.<\/p>\n<ol>\n<li><strong>Battery Discharge<\/strong><br \/>\nA car battery loses its charge if not used for some time. It is known as &#8220;self-discharge.&#8221; Over time, the battery loses power even when the car is off. If this happens too often, the battery may finally die completely.<br \/>\nFor example:<\/p>\n<ul>\n<li>If you don\u2019t use your car for a few weeks, the battery can get weaker.<\/li>\n<li>The car may not be able to start after several months.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Sulfation<\/strong><br \/>\nChemicals produce electricity inside a car battery. Lead plates and sulfuric acid are these chemicals. A problem known as &#8216;sulfation&#8217; can occur when the battery runs out of charge.<\/p>\n<p>Small crystals form on the battery&#8217;s lead plates as the sulfation. The crystals make it harder for the battery to hold a charge. The more crystals form, the longer the battery stays unused. Too much sulfation can do permanent damage to the battery.<\/li>\n<li><strong>Loss of Capacity<\/strong><br \/>\nWhen a car battery is not used for a long time, it will not be able to store energy. Even if you recharge it, the battery won\u2019t work as well as before. That is because the chemical reactions in the battery have been disrupted.<br \/>\nFor example:<\/p>\n<ul>\n<li>Even if the battery only lasts for 3\u20135 years with regular use, a new battery is pretty much a given.<\/li>\n<li>Even if you try to recharge it later, an unused battery may only last 1\u20132 years.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Corrosion<\/strong><br \/>\nIf a car battery has been left unused for too long, it can also corrode. You can see corrosion as a white, powdery substance on your battery terminals (metal pieces to which you connect cables). This can halt electricity flow and cause it to be hard to use.<\/li>\n<li><strong>Temperature Effects<\/strong><br \/>\nThe <a href=\"https:\/\/swiftbatteryspecialist.sg\/blog\/effects-of-weather-on-car-battery\/\">temperature where the car is stored can affect the unused battery<\/a>:<\/p>\n<ul>\n<li>Hot temperatures: Batteries can be damaged if overheated, getting them to discharge faster.<\/li>\n<li>Cold temperatures: If the battery is already low in charge and is exposed to extreme cold, it will freeze. A frozen battery can crack and stop working.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Parasitic Drain<\/strong><br \/>\nEven if a car is off, some of the smallest electrical systems (like a clock or alarm) will still use a little battery power. This is known as a &#8216;parasitic drain.&#8217; If the car isn\u2019t started regularly, this small drain can add up and completely discharge the battery.<\/li>\n<li><strong>Jump-Starting May Not Help<\/strong><br \/>\nJump-starting the car won&#8217;t always work if it&#8217;s because the battery is dead. Sometimes a battery that hasn\u2019t been used for a very long time has to be replaced instead of recharged.<\/li>\n<li><strong>Cost of Replacement<\/strong><br \/>\nCar batteries are not cheap. If you don\u2019t use your battery for a long time (or use it infrequently for a long period of time), your battery may die, and you won\u2019t be able to repair it. You will have to buy a new one. It can be anywhere from $50 to $200, depending on the car you have.<\/li>\n<\/ol>\n<p><strong>Read More:<\/strong> <a href=\"https:\/\/swiftbatteryspecialist.sg\/blog\/what-happens-to-car-battery-when-not-driven-for-weeks\/\">What Really Happens Inside a Car Battery When You Don\u2019t Drive for Weeks?<\/a><\/p>\n<h2>How to Prevent Problems with an Unused Car Battery<\/h2>\n<ul>\n<li><strong>Start the Car Regularly<\/strong><br \/>\nAt least once a week, start your car and run it for 10\u201315 minutes. In that way, it helps recharge the battery.<\/li>\n<li><strong>Use a Trickle Charger<\/strong><br \/>\nA trickle charger is a device that slowly adds power to your battery. In the absence of use, it keeps the battery charged.<\/li>\n<li><strong>Disconnect the Battery<\/strong><br \/>\nIf you\u2019re leaving your car unused for a few months, disconnect the battery. Any parasitic drain will be stopped.<\/li>\n<li><strong>Car Should Be Stored at the Right Temperature<\/strong><br \/>\nStore your car in a garage or a place of moderate temperature. Avoid extreme heat or cold.<\/li>\n<li><strong>Check the Battery Often<\/strong><br \/>\nCheck out battery terminals to ensure there\u2019s no corrosion. Clean them if needed.<\/li>\n<li><strong>Recharge the Battery<\/strong><br \/>\nExpect to have a full recharge of the battery before attempting to start the car if you believe it\u2019s been laying in the garage.<\/li>\n<\/ul>\n<h2>If the Battery Was Already Dead<\/h2>\n<ul>\n<li><strong>Jump-Start the Battery<\/strong><br \/>\nOne other trick you may use is to try using jumper cables and another working car to &#8216;jump-start&#8217; your battery.<\/li>\n<li><strong>Use a Battery Charger<\/strong><br \/>\nYou can add power back into your battery with a battery charger. It\u2019s important to follow instructions carefully.<\/li>\n<li><strong>Replace the Battery<\/strong><br \/>\nIf jump-starting or charging doesn\u2019t work, you may have to buy a new battery.<\/li>\n<\/ul>\n<h3>Conclusion<\/h3>\n<p>An unused car battery can suffer from many problems if a <a href=\"https:\/\/swiftbatteryspecialist.sg\/\">car battery<\/a> is not used for too long, such as losing its charge, sulfation, and even permanent damage. Even if you\u2019re not using your car, it\u2019s important to take care of your battery because that way, you can avoid these problems. <a href=\"https:\/\/swiftbatteryspecialist.sg\/blog\/how-to-retain-car-batterys-power-when-it-is-parked-for-prolonged-time\/\">If you&#8217;re not going to use the car for long periods of time<\/a>, or don&#8217;t want to park it in a garage, you can easily maintain your battery and avoid expensive replacements if you follow simple steps such as starting the engine regularly or using a trickle charger.<\/p>\n<p>Besides practical benefits, a healthy car battery means peace of mind. No matter if your car is parked for a few minutes or if it is stored for several months, you won\u2019t have to wonder if it will start when you need it. In situations where you\u2019re in a hurry or far from help, you\u2019ll avoid the stress and hassle of dealing with a dead battery.<\/p>\n<p>To sum it up a car battery is more than just a part of your car it is an essential part of your car that keeps everything running smoothly. If you don\u2019t use your car a lot, taking a few steps to protect your battery can help it last longer and keep running when you need it most. Proactive on battery condition will help you to avoid unnecessary problems, save money, and make the car ready to go.<\/p>\n\t\t\t\t\t\t\t<h3 style=\"margin-bottom:20px;display:block;width:100%;margin-top:10px\">FAQs <\/h3>\r\n\t\t\t\t\t\t<style>\r\n\t\t\t\t<style>\r\n#wpsm_accordion_3562 .wpsm_panel-heading{\r\n\tpadding:0px !important;\r\n}\r\n#wpsm_accordion_3562 .wpsm_panel-title {\r\n\tmargin:0px !important; \r\n\ttext-transform:none !important;\r\n\tline-height: 1 !important;\r\n}\r\n#wpsm_accordion_3562 .wpsm_panel-title a{\r\n\ttext-decoration:none;\r\n\toverflow:hidden;\r\n\tdisplay:block;\r\n\tpadding:0px;\r\n\tfont-size: 18px !important;\r\n\tfont-family: Open Sans !important;\r\n\tcolor:#000000 !important;\r\n\tborder-bottom:0px !important;\r\n}\r\n\r\n#wpsm_accordion_3562 .wpsm_panel-title a:focus {\r\noutline: 0px !important;\r\n}\r\n\r\n#wpsm_accordion_3562 .wpsm_panel-title a:hover, #wpsm_accordion_3562 .wpsm_panel-title a:focus {\r\n\tcolor:#000000 !important;\r\n}\r\n#wpsm_accordion_3562 .acc-a{\r\n\tcolor: #000000 !important;\r\n\tbackground-color:#90b0c2 !important;\r\n\tborder-color: #ddd;\r\n}\r\n#wpsm_accordion_3562 .wpsm_panel-default > .wpsm_panel-heading{\r\n\tcolor: #000000 !important;\r\n\tbackground-color: #90b0c2 !important;\r\n\tborder-color: #90b0c2 !important;\r\n\tborder-top-left-radius: 0px;\r\n\tborder-top-right-radius: 0px;\r\n}\r\n#wpsm_accordion_3562 .wpsm_panel-default {\r\n\t\tborder:1px solid transparent !important;\r\n\t}\r\n#wpsm_accordion_3562 {\r\n\tmargin-bottom: 20px;\r\n\toverflow: hidden;\r\n\tfloat: none;\r\n\twidth: 100%;\r\n\tdisplay: block;\r\n}\r\n#wpsm_accordion_3562 .ac_title_class{\r\n\tdisplay: block;\r\n\tpadding-top: 12px;\r\n\tpadding-bottom: 12px;\r\n\tpadding-left: 15px;\r\n\tpadding-right: 15px;\r\n}\r\n#wpsm_accordion_3562  .wpsm_panel {\r\n\toverflow:hidden;\r\n\t-webkit-box-shadow: 0 0px 0px rgba(0, 0, 0, .05);\r\n\tbox-shadow: 0 0px 0px rgba(0, 0, 0, .05);\r\n\t\tborder-radius: 4px;\r\n\t}\r\n#wpsm_accordion_3562  .wpsm_panel + .wpsm_panel {\r\n\t\tmargin-top: 5px;\r\n\t}\r\n#wpsm_accordion_3562  .wpsm_panel-body{\r\n\tbackground-color:#ffffff !important;\r\n\tcolor:#000000 !important;\r\n\tborder-top-color: #90b0c2 !important;\r\n\tfont-size:16px !important;\r\n\tfont-family: Open Sans !important;\r\n\toverflow: hidden;\r\n\t\tborder: 2px solid #90b0c2 !important;\r\n\t}\r\n\r\n#wpsm_accordion_3562 .ac_open_cl_icon{\r\n\tbackground-color:#90b0c2 !important;\r\n\tcolor: #000000 !important;\r\n\tfloat:right !important;\r\n\tpadding-top: 12px !important;\r\n\tpadding-bottom: 12px !important;\r\n\tline-height: 1.0 !important;\r\n\tpadding-left: 15px !important;\r\n\tpadding-right: 15px !important;\r\n\tdisplay: inline-block !important;\r\n}\r\n\r\n\t\t\t\r\n\t\t\t<\/style>\t\r\n\t\t\t<\/style>\r\n\t\t\t<div class=\"wpsm_panel-group\" id=\"wpsm_accordion_3562\" >\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t<!-- Inner panel Start -->\r\n\t\t\t\t\t<div class=\"wpsm_panel wpsm_panel-default\">\r\n\t\t\t\t\t\t<div class=\"wpsm_panel-heading\" role=\"tab\" >\r\n\t\t\t\t\t\t  <h4 class=\"wpsm_panel-title\">\r\n\t\t\t\t\t\t\t<a  class=\"\"  data-toggle=\"collapse\" data-parent=\"#wpsm_accordion_3562 \" href=\"javascript:void(0)\" data-target=\"#ac_3562_collapse1\" onclick=\"do_resize()\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"ac_open_cl_icon fa fa-minus\"><\/span>\r\n\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t \r\n\t\t\t\t\t\t\t\t<span class=\"ac_title_class\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span style=\"margin-right:6px;\" class=\"fa fa-car\"><\/span>\r\n\t\t\t\t\t\t\t\t\tHow long can a car battery sit unused before it goes bad?\t\t\t\t\t\t\t\t<\/span>\r\n\t\t\t\t\t\t\t<\/a>\r\n\t\t\t\t\t\t  <\/h4>\r\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t<div id=\"ac_3562_collapse1\" class=\"wpsm_panel-collapse collapse in\"  >\r\n\t\t\t\t\t\t  <div class=\"wpsm_panel-body\">\r\n\t\t\t\t\t\t\tMost car batteries can sit unused for 2 to 3 weeks without losing their charge.
