二、Two points of explanation 1. Impurities (especially iron ions) are very harmful to the battery, which will cause the battery to self-discharge and shorten its life. Therefore, pay attention to purity when injecting sulfuric acid and water. 2. The hydrometer is an essential tool to repair the batte...

Instead of using electricity to generate wind like a fan, a wind turbine uses the wind energy to generate electricity. The wind energy turns the propeller-like blades of the turbine around the rotor, which spins the generator, which produces electricity.   Wind turbines convert wind e...

Emergency lighting is an essential element in contemporary commercial environments. Buildings are equipped with adequate escape lighting to allow people to evacuate safely in the event of a mains power failure. Building owners are equipped with appropriate light fixtures that can aid in a successful...

At present, motorcycle engine starting are mainly based on lead-acid batteries. The designed life of lead-acid batteries is about 3 years. If the battery is irregular frequently charged and discharged, or high-power-fast-charging is frequently used, the battery life wil...

Maintenance-free batteries have the characteristics of low price, easy portability, and large capacity, and have been used in emergency lights, flashlights, UPS power supplies, motorcycles, electric bicycles, and electric tricycles. However, if it is used improperly, it will cause damage to the batt...

With rising energy prices and stricter global emissions standards, demand for renewable energy sources such as solar and wind power, as well as energy storage solutions, will continue to rise. The large amount of thermal energy of the sun makes it an attractive energy source. This energy can be dire...

The battery electrolyte allows electric charges to pass the battery plates between the two terminals. The electrolyte brings the chemicals needed for the reaction into contact with the anode and cathode, thus converting the stored energy into usable electricity. The electrolyte acts as a catalyst, m...

The failure of lead-acid batteries may be caused by a variety of reasons, such as vulcanization, water loss, thermal runaway, active material shedding, plate softening, etc. Next, we will introduce and analyze them one by one. 1. Vulcanization The process of charging and discharging lead-acid batter...
