New 12V 60 Ah lithium battery charging 12V lithium battery should be 3.74 x 4 = 14.963.74V, charging voltage is 4.2V, then lithium battery 12V should be 16.8V, current 6A, charge 10 hours, new battery first 3-5 times. should add 2 hours, or 12 hours, and you can increase or decrease the current later. Increasing the current will reduce the charging time, reducing the current will increase the charging time. Battery life mainly depends on the number of charges.
