What is the difference between the Unibody and non-Unibody MacBook Pro

I’m looking to replace the battery in my old MacBook Pro 17” Core 2 Duo 2.93. Model: A1297 (EMV 2272).

However, two options appear for a unibody and a non-unibody guide when I search the model/serial number. What does this mean? How do I know/find out which is the correct option to select for battery replacement instructions?

Many thanks for your time!

There is a website that tells you literally everything about your Mac model as long as you have the model or serial. I searched yours and have pasted the link below for you to check out. It looks like you do have a unibody model. The difference was just how the MacBook was built (using a single hollowed block of aluminum or piece by piece).

The battery on the unibody is internal. On the non unibody the battery was designed to be replaced by the user.

The battery for the A1297 is internal so you have a Unibody. Given it’s not as readily designed for replacement, a lot of them have varying quality as they’re not available through Apple as an OEM part. I would avoid eBay and AliExpress as they tend to be garbage every time. The only ones I would trust today are from OWC or iFixit.

Given the age of these and the 2011 GPU issues, it’s gotten a lot harder to find a good one. They’re still there but due to decline in demand there’s less good ones available.
