Dell Inspiron 13 7000 Laptop Battery Replacement and Testing

The notebook is the Dell Ran 7000 purchased in 2017. Compared with the expensive XPS, Ran 7000 has a very good price/performance ratio and became a popular product.

Since 2018, the battery life performance has not been as good as before. The battery life is only about 50% of the new time, so the idea of changing the battery began to appear.

If you need to replace the battery, you must open the bottom cover of the notebook, which is the "D" shell.

Most notebook D shells are designed to be easily disassembled, allowing users to add memory, hard drives, maintenance and cleaning. The red box in the picture is a Phillips screw.

After removing all the screws around and in the middle, starting from the hinge of the screen, gently pull up the D shell, as long as you don't use too much force, you can open it without damage.

This is what it looks like with the back cover removed. The left side is the main part of the notebook, and the right side is the bottom cover, which is the D shell.
