A laptop battery is a wear part: a lithium-ion cell loses capacity with every charge cycle, and after two or three years of use the machine may only run for a short while away from its charger. A replacement battery brings the runtime back and extends the laptop's life. This category has replacement batteries for the most common laptops, including HP, Dell and Asus models — made by Extra Digital and Green Cell among others. Compatibility is the deciding factor: check your machine's exact model and the battery model code printed on the side of the old battery (VI04 or HSTNN-DB2H, for example) and compare them with the product details. Make sure the voltage (V) matches the original, and look at the capacity — a higher mAh or Wh figure usually means longer use between charges. Check the battery's physical size and the position of the connector as well, so the new one fits without trouble.
