A Finishing charge is that part of the charging process which restores the final segment of a battery's charge, roughly between 90% and 100% SOC.

The final segment of a battery's charge is sometimes referred to as the "finishing charge" or "top-off charge." This is the final stage of the charging process, where the battery is charged to its full capacity. The purpose of the finishing charge is to ensure that the battery is fully charged and ready for use.

During the finishing charge, the battery charger will typically reduce the charging current and apply a lower voltage to the battery to prevent overcharging and damage to the battery. The finishing charge may also involve some form of maintenance charging, where the battery is kept at a fully charged state to help extend its lifespan.

The length of the finishing charge can vary depending on the type and size of the battery, as well as the charging method being used. It is important to follow the manufacturer's instructions for charging the battery to ensure that it is properly charged and to prevent damage to the battery or the charger.
