The Dell Inspiron 13 7359 2-in-1 is an excellent computer with a 3-cell, 43Wh battery, giving you 3-5 hours of battery life. Consider changing the battery if:

You find that the battery life has decreased significantly (the computer only lasts an hour or two on a charge).
The battery starts to charge to full too slowly.
Your device is alerting you of any critical battery failures.

Aside from the usual caution you'd give a battery, there are no real hazards involved with taking the backing of the computer off and replacing the battery. You won't need more than the actual replacement battery and a few tools to disassemble the computer, so follow this guide and keep your computer running for even longer. Just make sure to power off and disconnect the computer before you start taking it apart.

Caution: If the battery looks puffy, has started swelling, or leaking, please be very careful. Swollen batteries can catch fire or explode. For more information, take a look at this What To Do With a Swollen Battery guide.
