Persist in using the following methods to maintain motorcycle batteries, which can extend their service life to five or six years.

The maintenance methods for motorcycle batteries are as follows:

1) Inspection and supplementation of battery liquid level

The liquid level of motorcycle batteries must be between the upper and lower limits, and must not be lower than the lower limit. If it is lower than the lower limit, it should be replenished in a timely manner. When supplementing, do not inject dilute sulfuric acid again, otherwise the battery will be damaged due to high electrolyte concentration. Do not add tap water, river water, etc. Because it contains calcium, magnesium plasma, and impurities.

During charging, these substances adsorb onto the surface of the electrode due to ionization, damaging the battery. So it is necessary to add pure water, distilled water, or popular red battery replenishment solution in the market (which has shown good results in actual use). The liquid level of motorcycle batteries should be checked regularly, usually checked and replenished once a month. If the temperature is high in summer, it is recommended to check and replenish once every two weeks. It should be noted that sealed maintenance free batteries do not require liquid level inspection and replenishment, and do not open the sealing cover.

2) Check the status of the battery before charging

Check if the voltage of the motorcycle battery is below the standard value. If possible, check if the specific gravity of the electrolyte is below 1.28 (20 ℃). To observe the inside of the battery, if one or several battery cells corrode, the plates turn white, or there is material accumulation at the bottom, or the plates are warped, the battery should be replaced. If the battery terminals are dirty, corroded or oxidized, they can be cleaned with a wire brush. If the cleaning is not clean, you can drop a small amount of electrolyte to corrode the surface and wipe it dry with clean water.

3) Charging of batteries

This is an important part of motorcycle battery maintenance, which directly affects the lifespan of the battery. When charging, the current should not be too high, and it is recommended not to use fast charging. When charging, please use half the rated charging current and double the rated charging time. When charging, place the battery in cold water to cool down (water should not reach 4/5 of the battery). Because the battery releases a large amount of heat during charging, if it is not dissipated as much as possible, it will cause the electrode plate to bend and deform, resulting in damage to the battery. When charging, non sealed batteries should have their plugs open and be carried out in a well ventilated and away from sparks to prevent accidents caused by the generation of hydrogen gas during charging.

4) Detection after charging the battery

After charging the battery, do not rush to test it. It should be checked after standing for 30 minutes. Otherwise, it cannot accurately reflect the status of the battery. Firstly, check and correct the liquid level height, and then measure its voltage using a multimeter (preferably a digital multimeter). A 12 volt (6 volt) battery should reach or exceed 12.8 volts (6.4 volts).

If it is below 12.7 volts (6.3 volts), further charging is required. If it is below 12 volts (6 volts), it indicates that the battery is damaged and should be replaced. It must be noted that short circuit ignition is not allowed to determine the magnitude of the current. A headlight bulb with the same rated voltage as the battery can be connected to the battery, and the light should be observed after 5 minutes of illumination. If the light is bright and appears dim or goes out, it indicates that the battery is damaged and should be replaced.

In addition, the choice of charger is also very important. Chargers include variable voltage (current), constant voltage, constant current, etc. It is best not to use homemade chargers. It is best to use a dedicated charger for sealed maintenance free batteries. However, it should be noted that some constant voltage and constant current chargers cannot charge sealed maintenance free batteries.

The device that converts chemical energy into electrical energy is called a chemical battery, commonly referred to as a battery. After discharge, the internal active substances can be regenerated by charging - storing electrical energy as chemical energy; Convert chemical energy into electrical energy again when discharge is required. This type of battery is called a Storage Battery, also known as a secondary battery.

A battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

A Storage Battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to achieve recharging through reversible chemical reactions, usually referring to lead-acid batteries. It is a type of secondary battery. Its working principle: When charging, external electrical energy is used to regenerate internal active substances, storing electrical energy as chemical energy. When discharging, chemical energy is converted back into electrical energy for output, such as commonly used mobile phone batteries in daily life.

It uses a lead substrate grid (also known as a grid) filled with sponge shaped lead as the negative electrode, a lead substrate grid filled with lead dioxide as the positive electrode, and dilute sulfuric acid with a density of 1.26-1.33g/mlg/ml as the electrolyte. When the battery is discharged, the metal lead is the negative electrode, which undergoes an oxidation reaction to produce lead sulfate; Lead dioxide is the positive electrode that undergoes a reduction reaction to produce lead sulfate. When a battery is charged with direct current, the two poles generate elemental lead and lead dioxide, respectively. After removing the power source, it returns to its pre discharge state and forms a chemical battery. Lead acid batteries can be repeatedly charged and discharged, and their individual voltage is 2V. A battery is a battery pack composed of one or more individual cells, abbreviated as a battery. The most common is 6V, and other types of batteries include 2V, 4V, 8V, and 24V. The battery used in cars (commonly known as a battery) is a 12V battery pack consisting of six lead-acid batteries connected in series.

For traditional dry load lead-acid batteries (such as automotive dry load batteries, motorcycle dry load batteries, etc.), distilled water should be added after a period of use to maintain a density of about 1.28g/ml of dilute sulfuric acid electrolyte; For maintenance free batteries, distilled water is no longer required until the end of their lifespan. Principles of Chemistry

The equation is as follows:

Total reaction: Pb (s)+PbO2 (s)+2H2SO4 (aq) reversible symbol 2PbSO4 (s)+2H2O (l)

When discharging: negative Pb (s) -2e -+SO42- (aq)=PbSO4 (s)

Positive PbO2 (s)+2e -+SO42- (aq)+4H+(aq)=PbSO4 (s)+2H2O (l)

Total Pb (s)+PbO2 (s)+2H2SO4 (aq)=2PbSO4 (s)+2H2O (l)
