How do I know if a laptop battery will fit my device?

The most reliable method is matching the part number printed on your original battery. Also confirm the voltage and compare the battery shape/connector position with the product photos and specs.

Where can I find the battery part number?

Shut down the laptop, unplug power, remove the battery (if removable), and read the label printed on the battery itself. That part number is the best way to confirm compatibility.

Are different battery voltages interchangeable?

No. You must match the voltage on your original battery. Note: 10.8V equals 11.1V, and 14.4V equals 14.8V.

What should I compare before ordering a replacement battery online?

Compare the original battery’s part number and voltage first, then verify size/shape, connector type and location, latch position, and orientation against the product photos and specifications.

Can I use my laptop model number instead of the battery part number?

You can use a laptop model number to narrow it down, but the battery part number is more precise. One laptop model can support multiple battery types, so the printed battery part number is best.

What quick settings can extend laptop battery life?

Enable Battery Saver/Power Saver, reduce screen brightness, close unused apps/tabs, turn off Wi-Fi/Bluetooth when not needed, and avoid heat buildup by keeping vents clear.
