It does not include a battery, so you’ll pair it with a 12 V 23 A battery to enable testing. The device is suitable for both routine maintenance and more involved diagnostic sessions, offering a reliable tool without promising guaranteed outcomes. Its portability means you can carry it in a glove compartment or toolbox for quick, confident checks wherever you work.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What is the maximum load this tester can handle?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Maximum 20A at 48V, with a safe 10-second testing window.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does it include a battery?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Battery is not included; you need a 12V 23A battery.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Autokcan","offers":[{"title":"Default Title","offer_id":53087856427119,"sku":"B0DY7FRXQZ","price":24.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/0598\/3087\/files\/autokcan-circuit-fault-tester-front-display.jpg?v=1778662098","url":"https:\/\/taskholt.com\/products\/autokcan-circuit-fault-tester-20a-48v-car-fuse-tester-portable-waterproof","provider":"TaskHolt","version":"1.0","type":"link"}
