The following experience and steps are provided to help you determine whether the BYD battery needs to be replaced.
Pay attention to the battery jump: when your BYD vehicle has traveled about 30,000 kilometers, if a battery jump occurs during high-speed fast charging, that is, the battery power increases sharply in a short period of time (for example, from 80% to 100% in one minute) ), this may mean the battery is faulty. As we all know, when the battery is close to full, the charging efficiency becomes very low.
Conduct professional testing: If you encounter a power outage, it is recommended to go to a BYD authorized service center for battery testing. They examine each cell of the battery and record the voltage difference between cells. If the voltage difference of a cell exceeds 0.1V, you have the right to replace the battery according to the warranty policy. Here, I would like to remind everyone to cherish the vehicle warranty and the three-electricity lifetime warranty.
Extended warranty period: If you purchase extended warranty service, your Sanden lifetime warranty will be extended. It should be noted that the warranty period for the entire vehicle, especially the tablet, is only 3 years. If your extended warranty period is 2 years, your vehicle warranty will be extended to 5 years. This way, when something goes wrong with the tablet, you don’t have to spend money on repairs, but can just replace it for free.
I hope the above information will be helpful to you in order to determine whether the BYD battery needs to be replaced.
