How to Change a Dell Inspiron Laptop Battery. According to Dell, the battery in your Inspiron notebook should last somewhere between 18 to 24 months before you see a drop in its performance. After that, you'll likely notice that the battery's charge won't last as long as before. When this happens, you should consider switching the old battery out for a new one. The process is simple and should only take you a few minutes to complete. Read on to learn how to change a Dell Inspiron laptop battery.

Step 2
Save any open files on which you're working. Since turning the system off isn't required when changing the battery, this is more of a precaution than a necessity.
Step 3
Plug your Inspiron AC adapter into a nearby wall socket. Then, connect the end of the adapter cable to your notebook's power socket.
Step 4
Turn your notebook over and find the battery latch. Slide the latch into the release position and pull out the old battery.
Step 5
Install the new Dell battery by simply popping it into place. The alignment of the battery should be easy to figure out, since there's only one side of it that connects to the receptor pins in your notebook's battery bay.
Step 6
Make sure the battery latch pops back into the locked position. If it's jammed in the unlocked position, gently wiggle the battery back and forth to pop it back.
Step 7
Keep your notebook plugged in to the wall socket in order to charge the new battery. You can check the status of its charge by clicking on the system tray icon shaped like a battery.
