How to maintain electric motorcycle batteries?

The battery life is about two years and can be extended if you care properly.

First of all, the most afraid of low temperature, low temperature battery capacity than at room temperature much lower capacity. Batteries that are normally used in warm places will suddenly run out of electricity in cold places.

Therefore, before the cold season comes, the electrolyte height should be checked. If it is necessary to replenish the electrolyte of the battery, adjust the specific gravity of the electrolyte, and check its storage status, it must be

Charge when needed. At the same time clean the battery wiring bundle, and apply special grease to protect, prolong battery life.

Factors affecting battery life

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

The liquid level of the electrolyte

When charged, the water in the electrolyte is lost to hydrogen and oxygen, which reduces the amount of electrolyte. When the electrolyte level is lower than the polar plate, the polar plate material will be exposed to air, so that the material will become hard and will not be able to play a chemical role. In addition, the concentration of the remaining electrolytes will be too high, which will degrade the performance of the polar plate and have too many electrolytes. It is easier to splash out and cause corrosion of the pile head and increase resistance.

II Overcharge

The battery is full of electricity and it is still overcharged with excess current. In any case, overcharging can damage the chemistry in the battery. When over-charging, the water in the electrolyte decomposes into hydrogen and oxygen bubbles. These bubbles will flush out the active material of the polar plate. At the same time, over-charging will cause the battery to overheat, which will cause the positive plate material to oxidize and deform the polar plate., In addition, when the battery is out of gas, it will flush the electric water into a small particle and spray it outside the battery, causing the head of the battery, the seat frame and the engine parts to corrode, and cause the top of the battery to leak electricity.

Third, insufficient charging and plate vulcanization

When the charging system is damaged and the battery is parked or started too much, the battery is discharged at any time because there will be a layer of aluminum sulfide on the polar plate during discharge. If there is too much lead sulfide, it will become a crystal. This situation is called sulfuration. The crystal is not easy to recover when charging, so the battery will become useless.

Four electrolytes are too strong.

Each time the battery electrolyte is insufficient, if no water is added, and the electric water(dilute sulfuric acid) is used to supplement it over time, the sulfuric acid component in the electrolyte increases, the electrolyte becomes concentrated, and when the battery is full of electricity, strong acid will corrode the grid in the pole.

V Excessive water addition

If an excessive amount of water is added to the battery, when charging, the electric water will overflow the battery due to an increase in temperature, which will corrode the pile head, increase the resistance, and reduce the charging rate; And the battery's storage power is leaked from the wet top, where sulfuric acid will also be lost. If distilled water is added, the electrolyte will become thinner and the charging will be insufficient.

Six cycles

When the battery is charged, the discharge is completed and the charging is completed, which is called a cycle. If the cycle of the battery continues to occur, the active material on the plate will peel off to the sedimentation chamber, which will reduce the energy of the battery and shorten its life. Th

Seven temperatures.

Changes in the weather and the heat generated by overcharging reduce the life of the battery, but the low temperature in winter also damages the battery. If the electrolyte freezes into ice when it is too cold, it will cause the battery shell to rupture, and the freezing point of the electrolyte depends on the degree of charging. A fully charged and normal concentration of electrolytes at -50. F(-45 · 5. C) It will not freeze. After a discharge of the battery, its electrolyte moisture increases at 18. F(-7. C) It will freeze. When the temperature is low, the battery is not easy to charge. As shown in Figure 2-6 .1, the battery is 80. F(26.7). C), 32. F(0). C) and 0. F(-17 · 8. C) The output energy of the time, from the figure, the lower the temperature, the smaller the energy that the battery can rotate; In addition, the colder the engine, the greater the energy required to start.

Eight Vibration

The battery should be fixed steadily to the battery stand to prevent vibration. The vibration will cause the active material on the polar plate to fall and reduce the life of the battery. The vibration will also cause the connector in the pole to loosen. When the vibration is severe, It also breaks the battery case or loosens the cable connector.

1-2 months must be charged once, can not be damp(air humidity can not exceed 75 %), interface must not be exposed to metal products. In addition, it will discharge itself, It 'll be out in about four months, so I suggest you use it. It 'll dry up in a few years.
