Green, red, white and tri-color battery indicator pro, commonly known as electric eye, can directly reflect the current situation of the battery. You can know the battery charge by observing the electric eye.
Electric eyes are mainly divided into three states, and the colors of battery electric eyes of different manufacturers will be different:
Green or blue indicates good condition; Black or red indicates that charging is needed; White indicates that the battery needs to be replaced.
Usually at the top of the battery, there is a small glass window that can display colors. It shows that green is the best, blue is the medium and red is the worst.

Automobile battery maintenance:
1. Avoid parking vehicles for a long time.
The battery installed in the car will discharge itself in the process of long-term storage, so it is best to drive once a week, and the journey is preferably more than 20 minutes, which is convenient for charging the battery when the car is driving.
2. Close the window before flameout.
The switches of car windows and skylights are powered by batteries, so it's better to close all the windows before the flameout, instead of pressing the lock button for a long time after the flameout or even after leaving the car.
3. Keep the battery clean and tidy.
Regular inspection is an effective means to prolong the service life of automobile batteries. Use professional battery electrode brushes or discarded toothbrushes to clean the dust and corrosion on the positive and negative electrodes of the battery. Apply vaseline or fatty substance on the contact surface to form a protective film.
