The answer to this question largely depends on the age and condition of your laptop battery. In general, it’s a good idea to replace your battery every 2 years, since batteries tend to lose their ability to hold a charge over time. If your battery is fairly new and hasn’t started exhibiting any problems, you may be able to wait without replacing it. However, if your battery is older or starting to show signs of wear, it might be a better idea to get it replaced sooner rather than later.
