During the charging process, the temperature of the battery will rise, but it is not allowed to exceed 45 ° C; if it exceeds 45 ° C, the charging should be stopped, and the charging can be continued only when the temperature drops below 35 ° C. If the wheelchair is not used for a long time, recharge the battery at least once a month.

• The battery has a service life. After using it for a long period of time, if you find that the mileage of the electric vehicle after the charging is significantly different from the nominal mileage, please replace the battery.

(1) For lead-acid batteries, there are two left and right battery boxes. Each battery box contains a lead-acid battery. The "+" on the battery indicates the positive electrode and "-" indicates the negative electrode.

The steps to replace the battery are as follows:

a.     unscrew six self tapping screws from the inside of the wheelchair, i.e. the back of the battery box, and open the back cover. The method is the same on the left and right sides;

b.    Take the battery out of the battery box, remove the positive and negative lead wires with a wrench, install a new battery and fix the positive and negative lead wires, and the remaining harnesses do not need to be changed;

c.     Pay attention to the difference between the positive and negative poles of the harness on both sides, the right battery connecting wire, red connected to the positive pole (+), brown connected to the negative pole (-); the left battery, red connected to the positive pole (+), black connected to the negative pole (-).

(2)  If it is a lithium battery, there is only one battery box on the right side. There is a lithium battery in the battery box. Red on the battery indicates positive and black indicates negative. The steps to replace the battery are as follows:

a.     unscrew six self tapping screws from the inside of the wheelchair, i.e. the back of the battery box, and open the back cover;

b.    Take the battery out of the battery box, separate the connector by hand, install a new battery and plug the connector back in, and the rest of the harness does not need to be changed.
