However, problems can still occur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many are interested in identifying faulty lithium-ion batteries, which may exhibit symptoms like reduced capacity, low voltage, rapid self-discharge, overheating, and swelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article will discuss how to check for lithium-ion battery failure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Causes of Lithium-Ion Battery Failure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Lithium-ion batteries, despite BMS protection, remain vulnerable to internal and external factors that can cause failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Internally, <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/holobattery.com\/custom-lithium-battery-pack-manufacturing\">manufacturing<\/a> issues like price gouging, subpar materials, and sloppy production can compromise durability and performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Externally, environmental conditions like temperature, humidity, air pressure, and physical stress can negatively impact battery health over time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Signs Lithium-Ion Battery is Failing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your lithium-ion battery won&#8217;t last forever, but there are some telltale signs that it&#8217;s starting to fail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Longer Charging Time<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Slower charging indicates your battery is losing capacity and won&#8217;t hold a charge as long.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is an early sign your lithium-ion battery is failing, as these batteries gradually lose energy storage and efficiency over time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Shorter Battery Life<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A rapid discharge rate is an initial sign of lithium-ion battery damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your battery needs frequent recharging, it may indicate the battery is wearing out and needs replacement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Overheating<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive heat during battery use or charging is a concern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some heat is normal, but abnormal temperature increases could indicate internal issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Monitor any noticeable heat rise, as overheating affects performance and poses safety risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive heat may lead to <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/holobattery.com\/thermal-runaway\">thermal runaway<\/a>, where the temperature continues rising, making the device dangerously hot. This signals the battery needs closer inspection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Inability to Charge<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A dead battery is a common problem for portable electronics users.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a device won&#8217;t charge, it likely indicates a dying battery that needs replacement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Unexpected Power Offs<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When a device suddenly shuts off despite ample battery life, it often indicates a failing lithium-ion battery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If this persists, the battery should be replaced by a professional.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Inaccurate Battery Indicator<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Even with a full battery meter, devices can unexpectedly die, indicating a failing battery that needs replacement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Poor Response Time<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your device&#8217;s poor response time can indicate a weak battery, or may result from data overload or software issues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Low Voltage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Batteries gradually lose voltage over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a certain voltage is detected, the cutoff circuit disconnects the battery immediately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a 4.2V lithium-ion battery may change to 3.7V after repeated charging and discharging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The device stops functioning once the battery drops below 3.4V, and it&#8217;s unusable at 3. 0V.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. High&nbsp;Frequency&nbsp;Of Self-Discharge<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Batteries eventually lose their charge when not in use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">High-quality lithium-ion batteries have a low self-discharge rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remove the battery after two hours and check the charge level before unplugging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the readings are outside the specified range, assume the battery is broken.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10. Swelling or Bulging<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Swelling or bulging in the battery casing indicates internal problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A deformed battery signals potential failure and safety risks, including leakage or explosion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Swelling occurs due to gas buildup from internal component breakdown or damage, causing the battery to expand.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Troubleshooting Lithium-Ion Battery Issues<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Test your lithium-ion battery immediately if you suspect it&#8217;s malfunctioning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Issues like fires can be caused by a defective battery. Use a multimeter to test the battery.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-1024x684.jpg\" alt=\"use a multimeter to test the battery\" class=\"wp-image-2513\" srcset=\"https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-1024x684.jpg 1024w, https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-300x200.jpg 300w, https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-768x513.jpg 768w, https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-1536x1025.jpg 1536w, https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery-600x401.jpg 600w, https:\/\/holobattery.com\/wp-content\/uploads\/2024\/07\/Use-a-multimeter-to-test-the-battery.jpg 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Remove it from its case and connect the multimeter&#8217;s positive and negative leads to the battery terminals. Power on the multimeter and activate &#8220;DC Voltage&#8221; mode. Place the probes on the terminals and read the results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A damaged lithium-ion battery may show a voltage below its normal 3. 7V level, such as 3. 5V or less.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check the battery&#8217;s capacity by fully discharging and taking a new reading &#8211; a damaged battery will have less power.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Replace the lithium-ion battery as soon as possible if you suspect damage. It&#8217;s not worth the risk to continue using a compromised battery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6 Ways to Extend the Lithium-Ion Batteries Life<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">1. Use a high-quality charger made for lithium-ion batteries to avoid reducing battery life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. Avoid overcharging &#8211; don&#8217;t leave batteries charging overnight unless necessary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3.
