Does a new battery need to be charged for 12 hours?

[DelMiguel]

New car batteries do not need to be charged for 12 hours. For the first charge of a new electric vehicle, there is no need to deliberately drain the battery before charging. Lead-acid batteries do not have a memory effect. It is generally recommended to charge the battery when the remaining capacity is between 30% and 40%, which is the optimal time. Charging for more than 12 hours is generally not advised. Relevant information about car batteries is as follows: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working Principle: It uses lead plates filled with spongy lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
