Product Description

Battery indicator work theory

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 states.

The 1-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.

The two balls model

It will provide a bright green indication if the battery is charged,clear and bright indication if the battery is discharged.

Red indication if the electrolyte level is low.

Advantages:

Be of easy assembly, low cost and small sizes
Determines the battery capacity at a glance
Stably indicates charging state with the theory of electrolyte density
Provides temperature compensation to assure accurate readings of battery temperature
Indicates at low electrolyte level
Reduces the necessity of OCV (Open circuit voltage) test, saving time and efforts
Improves satisfaction of end-user
