Chapter 6 Battery Maintenance Guide
This product uses a lead-acid maintenance-free battery, which has the functions of
maintenance-free, maintenance-free, and automatic pressure relief. If it will not be
used for a long time, please disconnect the positive pole of the battery and store it.
1) Why lead-acid battery life is short?
The battery is undercharged for a long time, and it is not charged for a long time after
discharge. During the use process, there is often an overdischarge phenomenon. The
standard charger is not selected during charging, resulting in overcharge
phenomenon. The voltage is different, and a low-voltage working state is formed for a
long time.
2) After the battery is used up, how should it be stored?
The battery is a sensitive product. If it is not used for a long time, it is best to take the
battery out of the machine and put it in a dry place at room temperature; because the
battery is placed inside the machine and is not disconnected from electrical
appliances and circuit boards, it will form a battery Continuous maintenance
discharge.
3) What is overdischarge and how does it affect the performance of the battery?
It refers to the phenomenon that the electricity stored in the battery continues to
discharge after reaching the minimum working voltage. After the battery is
over-discharged, the voltage drops sharply in a very short period of time, and the
entire internal reaction system of the battery is disordered. Reduces battery usage
time and extends battery charging time.
! ! Deep discharge is strictly prohibited
◆When the battery is used up every day, please make up the power in time. No
matter how much the remaining power is, the battery needs to be fully charged
and stored.
