Charging System - Sony BC-L50 Operating Instructions Manual

Charging System

When this unit is used to charge two battery packs at the same
time, charging of one battery pack starts when the other battery
pack is 80% charged. Under the conventional charging system,
charging of one battery pack did not start until the other was
100% charged. This unit's new charging system enables
quicker charging of two battery packs.

This allows two battery packs to be charged in less time than
previously.
