There are a lot of myths around this topic that has prevailed for a lot of time in the SEO industry. One of those myths is "Google does not crawl content in accordion" or "Content hidden in tabs is not crawled by Google". Let me explain it to you in brief.
What Google thinks about Tabbed or Accordion Content?
Google has always been focusing on improving user experience in one way or the other. It does not matter what you do on your page, it will understand the front-end of your website and will display it to the user accordingly. This is not a self-sufficient explanation though, let me, deep-dive, into it.
For example, you set your background to a hard color "Grey", and at the same time, the font color that your website is using is grey or dark grey. Now, Google will consider this as a black hat technique, as it will predict that you are trying to hide content from the users. This is not an appropriate example but this was to explain a simple thing about "User Experience". Here is how tabs look like.

How tabbed or accordion content affects User Experience?
As we know that Google focuses on delivering a good user experience, we must too focus on it if we want our website to be on top of search results. Because Google really cares about user experience. We are not talking about other search engines out there, but Google definitely has a lot to do with how users will interact with your website.
Now let us take an example of content that is too lengthy to fit on a single page, will it be a good idea to keep all the content visible?
The answer would be definitely "NO".
The Concept of Tabbed Content
Tabbed content was originally used by website owners to give users complete information, but take less of their screen space. For example, you want to learn about Google's EAT SEO, you will probably look for the things that you don't know and will likely skip the things that you are already aware of.
Some frequently asked questions about Tabs, Accordions and hidden content

It will definitely be a good idea to use tabs or accordions in your content if the content length is a lot. And this is a good practice if you are looking to make your site as user-friendly as possible.
