Why does a newly replaced battery take so long to charge and still not reach full capacity?
2 Answers
It may be caused by improper charging methods, circuit faults, or charger malfunctions. Causes of improper charging methods: The basic requirements of batteries for charging technology are the foundation for analyzing various charging techniques. The basic requirement of electric vehicle batteries for charging is that the charging current should be less than or equal to the current that the battery can receive. Otherwise, excess current will deplete the electrolyte too quickly, leading to the following hazards. Charging process: It is the reverse reaction process of the discharge electrochemical reaction. If the charging electrochemical reaction process proceeds under ideal conditions, this process should be mutually reversible, meaning the amount of electricity charged should be roughly equal to the amount discharged. However, under severe gassing conditions, the effective charging electrochemical reaction consumes less than 40% of the total electricity, resulting in a waste of more than 60% of the electrical energy.
I also encountered this issue when I just replaced the new battery. It charged all night but still didn't reach full capacity, which was really frustrating. There could be several reasons: First, it might be a problem with the charger. If the charger has insufficient power or is faulty, it can't fully charge the battery, so you need to check if the charger model is compatible. Second, the new battery itself might be defective. Even though it's newly installed, it could have issues from the factory or might not be fully activated. It's best to return to the purchase store for testing. Third, there could be wiring issues, such as poor contact or impurities on the battery terminals, which can affect charging efficiency. Fourth, the charging method might be incorrect, such as continuous charging for too long, causing the battery to overheat and damage it. It's recommended to first try using a high-quality charger. If the problem persists, seek a professional repair shop for inspection. Don't overlook safety, as this issue could lead to overvoltage and damage other components.
