I have never met anyone who wants to measure the capacity just by installing the battery. Discharge takes time. You have to wait for the discharge to end automatically to have a complete capacity in the discharge stage\u003cbr\u003e\u003cbr\u003eThis product uses the DC two-wire method to test the battery internal resistance principle:\u003cbr\u003eDC impedance is based on the physical formula R=V\/I, the test set The battery is forced to pass a large constant DC current (currently 10A-80A is generally used) in a short period of time (usually 2-3 seconds), and the voltage at both ends of the battery is measured, and the current battery internal resistance is calculated according to the formula. The DC two-wire test internal resistance is the result of the middle line resistance, and the result is used for reference comparison between batteries tested in the same batch. Due to the influence of contact resistance and battery self-loss, the internal resistance may not be identified normally and cannot be measured. For those with high requirements for internal resistance measurement accuracy, the TS235 internal resistance tester (AC four-wire method) can be used for internal resistance testing.\u003cbr\u003e\u003cbr\u003e","brand":"GadgetHQ","offers":[{"title":"Default Title","offer_id":52633315508571,"sku":"TBD0605443301A","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/1041\/7755\/files\/TBD0605443301A.jpg?v=1774031882"},{"product_id":"ip2312-type-c-polymer-ternary-lithium-battery-fast-charging-board-3a-5v-to-4-2v-4-35v-battery-charging-board","title":"IP2312 Type-C Polymer Ternary Lithium Battery Fast Charging Board 3A 5V to 4.2V 4.35V, Battery Charging Board","description":"1.
