Usually, the life span of a laptop's battery would range from 2-3 years max depending on the type of handling and usage. Based on your description, I think you do need a new battery.How long do we need to change laptop battery?
Usually you change it every 2-3 years because if you kept on charge all the time, it overcharged so its weak. i suggest change it and when it reaches a 100% charge take it of charge and use it with the battery power. That way the battery lasts 6-7 years.
for a laptop battery, it usually used for two or three years. if it cant charge. you should change a new one.
