Laptop battery charges but doesn't last long
It is normal for a laptop battery to lose its ability to hold the maximum capacity as it ages. If your laptop computer can charge the battery, but it doesn't last long enough or is only capable of holding 25% or less of its maximum capacity, the battery should be replaced.
