Battery indicator work theory:
1,The red and green gravity balls are used for the battery indicator,The gravity corresponds to Critical density of battery electrolyte,when it works,either ball sinks or floats,leading to different indications,meaning to indicate different battery status.
2,The *-ball model
It will provide a bright green indication if the battery is charged,a dark indication if the battery is discharged,and a clear and bright indication if the electrolyte level is low.
3,The two ball model
It will provide a bright green indication if the battery is charged,a clear and bright indication if the battery is discharged,red indication if the electrolyte level is low.
Advantages:
Determines the battery capacity at a glance
Basing on specific gravity,indicates stable charging status.
Provides temperature compensation to assure accurate reading at any battery temperature
Indicates a low electrolyte level.
Reduces the demands for OCV(Open Circuit voltage)testing,thereby saving time.
Reduces customer warranty claims,improve end-user satisfaction.
