About the true and false identification of lithium-ion batteries

Source: 2020 - 03 - 24 16:00 hits: first lithium batteries appeared on market of true and false identification lithium battery true and false identification cadmium nickel metal hydride nickel-cadmium lithium ion battery and lithium polymer batteries as metal lithium ion batteries. Experts remind you can use the following method to detect authenticity: 1 self-discharge rate. Lithium ion battery 8% a month; The lithium polymer battery is 20% per month; Nickel metal hydride nickel-cadmium battery 100% / month; Lithium battery is 1% 2% per month. 2, lithium battery series battery has no memory effect. 3. Insert special test card numberical machine's, press '#' key into the test state, then press '#' 490. If the phone display 'Battey Rd fault, then it is a fake piece of lithium battery.
