There are also many stories of poorly-made off-brand phone replacement batteries exploding and sometimes injuring users or causing serious fires.<\/p>\n<p>Lithium batteries require sophisticated safety electronics to operate without these issues, and punctures or impacts can cause a battery fire regardless of what safety measures are built into the device.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Airline_Battery_Limits_Are_About_Limiting_Risks\"><\/span>Airline Battery Limits Are About Limiting Risks<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Airlines <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>ly limit battery sizes to 100Wh and below without you needing special permission. Larger batteries may be allowed if you declare them beforehand and let the airline inspect them before boarding, with an upper limit such as 160Wh being common. These larger batteries might have to be stored in a special hold managed by the cabin crew.<\/p>\n<p>The number of batteries you may bring may also be limited. For example, you might be limited to two 100Wh power banks per person. High-end laptops will often have 99.9Wh batteries specifically since this is under the general limit that most airlines require.<\/p>\n<p>Limiting battery sizes like this is about balancing the needs of passengers with the potential size of a battery fire. In most cases, these batteries must be part of your carry-on luggage so that any battery fires can be dealt with by the cabin crew. If lithium battery packs were to ignite in the cargo hold inside someone\u2019s suitcase, it could get out of control without any intervention being possible.<\/p>\n<p>A 100Wh is a lot of energy, so it\u2019s a rather generous allowance, and presumably, those who assess risk when setting policy feel that batteries of this size are still manageable should the worst happen.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Batteries_Are_Getting_Safer\"><\/span>Batteries Are Getting Safer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While it may take some time, one day, these restrictions may no longer apply.
