How to maintain electric motorcycle battery?

Battery life is about two years, which you can extend if you care.

First, the temperature is most afraid of low temperature, and the battery capacity in a low temperature environment is much lower than that at normal temperature. A battery that is normally used in a warm place will suddenly lose power in a cold place.

Therefore, the electrolyte height should be checked before the cold season. If necessary, the electrolyte of the battery should be replenished, the specific gravity of the electrolyte should be adjusted, and the storage condition should be checked.

Charge when you need it. At the same time, clean the battery wiring harness and apply special grease to protect the battery life.

Factors affecting battery life

Each battery has a certain life, but there are many factors that can shorten its life, as described below:

First, the electrolyte level

When charging, the moisture in the electrolyte is lost to hydrogen and oxygen, which reduces the amount of electrolyte. When the electrolyte level is lower than the plate, the plate material is exposed to the air, which makes the material harder and less prone to chemistry. In addition, the remaining electrolyte concentration will be too high, which will degrade the performance of the plate, too much electrolyte, and it is easy to splash and cause corrosion of the pile head and increase the resistance.

Two overcharge

The battery is fully charged while still being charged with excess current. In any case, overcharging can damage the chemical action in the battery. When overcharged, the water in the electrolyte is decomposed into hydrogen and oxygen bubbles, which will wash away the active material of the plate, and overcharging will cause the battery to overheat, which will oxidize the material of the positive plate and deform the plate. When the battery is angry, the electric water is washed into small particles and sprayed out of the battery, causing corrosion of the battery pile head, the frame and the engine parts, and causing leakage of the top of the battery.

Three undercharge and plate vulcanization

When the charging system is damaged, there is too much parking or starting, the battery is discharged at any time because there is a layer of aluminum sulfide on the plate when discharging. If there is too much lead sulfide, it will become a crystal. This situation is called sulfation, and the crystal is not easy to recover during charging, so the battery becomes useless.

Four electrolytes are too strong

Every time the battery electrolyte is insufficient, if it is not added with water, it will be replenished with electric water (diluted sulfuric acid solution). The sulfuric acid content in the electrolyte increases and the electrolyte becomes thicker. When the battery is fully charged, the strong acid will corrode. In the grid plate.

Five over water

If excessive water is added to the battery, when charging, the electric water will expand due to the temperature rise and overflow the battery, which will corrode the pile head, increase the electric resistance, reduce the charging rate, and make the battery storage power leak from the wet top. The sulfuric acid is also lost. If distilled water is added, the electrolyte will become thinner and the charging will be insufficient.

Six cycles

When the battery is fully charged, after the discharge is completed, the recharge is completed, which is called a cycle. If the cycling of the battery occurs continuously, the active material on the plates will peel off into the precipitation chamber, which will reduce the energy of the battery and shorten its life. "

Seven temperature

The change in weather and the heat generated by overcharging shortens the life of the battery, but the low temperature in winter also damages the battery. If the electrolyte freezes to ice when it is too cold, the battery case will rupture, and the freezing point of the electrolyte depends on the degree of charge. A fully charged and normal concentration of electrolyte is at -50. It will not freeze when f(-45·5.c). After a discharge of the battery, the electrolyte water content increases at 18. f(-7·7.c) will freeze. When the temperature is low, the battery is not easy to be charged. As shown in Figure 2-6·1, the battery is charged at 80. f (26.7.c), 32. f(0.c) and 0. The output energy at f(-17·8.c) can be seen from the figure. The lower the temperature, the smaller the energy that the battery can turn. In addition, the colder the engine, the greater the energy required for starting.

Eight vibration

The battery should be stably fixed on the battery holder to prevent vibration. The vibration will cause the active material on the plate to fall and shorten the battery life. The vibration will also loosen the connector inside the pole, and when the vibration is severe, the battery will be made. The casing is broken or the cable joint is loose.

1-2 months must be charged once, can not be damp (air humidity can not be greater than 75%), the interface must not touch metal objects. In addition, it will discharge itself, it will be finished in about 4 months. So I suggest you best Use it. It will be scrapped due to the dryness of the electrolyte in a few years (but it can be repaired, but it will be troublesome).

The battery has a service life of about two years and can be extended if you care properly.

In addition, it will be self-discharged and will be completed in approximately 4 months. So I suggest you use it best. Since the electrolyte will dry out in a few years, it will be discarded (but it can be repaired, but it can be cumbersome).
