Does the replacement battery in my MacBook worth the hassle?

I bought a second hand old retina Macbook Pro recently. The previous owner said it had got its battery replaced a bit more than a year ago. It is in fact only at 224 cycles, but it lasts for a pretty short time: only using a browser reading or watching youtube its max is a bit less than 2 hours (more about one and a half), but if I use a second monitor and get into heavier multitasking it lasts only for 30 minutes max. Long story short I basically got a desktop instead of a laptop...

I know it is an old machine so I should not expect the same performance when it was new, but the manufacture date of the battery is 2015 so I thought it could be mainly the fact that altough it is unused, it is still an old battery.
I was thinking about getting a new ifixit battery for my machine to make the laptop usable, because they are (I believe) higher quality and more recently manufactured compared to a random part from the webs.

If you have replaced the battery with the new one can you please share your experience about its usability? It would help me a lot making the decision.

In advance thank you if you are willing to help me out.
