Battery swelling or leaking in your tablet may occur over time due to repeated charging and discharging, and it is not necessarily a quality issue with the battery. While it may not pose an immediate safety risk, continuing to use a swollen battery can lead to jamming or charging performance problems. Therefore, it is advisable not to use the tablet with a swollen battery and instead consider replacing it with a new one.
To prevent damage to the battery, we recommend charging and discharging it at least every three months when the tablet is not in use and ensuring it is charged to 100%. This maintenance practice can help prolong the battery's lifespan and reduce the risk of swelling or other issues.
