There is no battery, it's wired so unsure why it asked me to rate the battery life. Super reliable and pretty easy to use. Some of the more expensive brands have a nice customizable interface that is easily accessible on the pc you are using through a program that is usually user friendly to control lights, mouse dpi, and programming other buttons. Although you get what you pay for. No adjustable weights, pre-programmed light settings that are almost the same, and extra buttons aren't justifiable to spend $60 on a mouse right now 🤦♀️
