4 Stages of Battery Charging. The charging process of a battery can be divided into four distinct stages. These are the bulk stage, absorption stage, float stage, and equalization stage. Each stage has a specific purpose and role in ensuring that the battery is properly charged and ready to use. The first stage is the bulk stage.

Manufactured lithium batteries usually need to be pre-charged before being officially charged. Pre-charging is the process of charging the battery with a lower current. Its main purpose is to extend battery life and improve battery performance. The following is a detailed explanation on the necessity of pre-charging lithium batteries.
Precharging continues until the pre-to-fast charge voltage threshold is reached, a threshold that is usually recommended by the battery manufacturer (commonly between 2.6 and 3.0 V). ... The second factor that may have an effect in the actual charge current level is the operating state of the system during the charging process. When the ...
