asus tuf gaming a15 fa506 battery aging problem

Batteries are essentially consumables. Li-ion batteries, featuring continuous chemical reactions, will naturally decline over time and lose capacity.

After using a battery for some time, under some conditions it will have a degree of swelling. This will not create safety issues.

Swollen batteries should be replaced and discarded properly, though they do not create safety issues. When replacing swollen batteries, do not discard the old swollen battery into common domestic waste.
