Battery Failure in a 2 year old Dell Inspiron 13 7370

[Michelle T]

I purchased a Dell Inspiron 13 7370 2 years ago.  I checked the specs carefully and purchased and returned 2 other laptops before settling on this one.  I've liked everything about it except the fact that it runs hot and the fan is frequently on and its noisy. Previously I had a MacBook Pro and it ran very cool.  I was surprised that a laptop could get this hot and not be malfunctioning. Now after two years, the battery is on the brink of failure and I have to purchase a new one.  I didn't link the heat with the battery life (I'm not that techy) but someone who a computer science student informed me that battery failure is a common Dell laptop problem, due to the heat.  MicroCenter will charge me the cost of the battery plus $60 for labor! Ouch! I see that Dell has a video for battery replacement.  Is it as simple as unscrewing the panel, removing the battery and putting the new one in? Is there anything to connect?  Can I successfully change the battery myself? It calls for a small Phillips (I have that).  Thank you.
