Question MacBook Pro Battery Replacement

[X_Gumby_X]

I have a MacBook Pro 2019 2.5 GHz Intel i5 8GB that I do enjoy throughly. I bought 2nd hand on Facebook and regret that I didn't go through the settings at all when I pirchased the MacBook. I've got the lot of Apple products iPhone 16 Pro Max, iPad (th Gen and my GF just got me Apple Watch Series 4 for the holiday. The battery on my laptop is in critical state and required service. Now, unfortunately, I have the same MacBook but my ex had intentionally damaged it to the tune of ov er $500 to fix. The battery oil that unit is in good condition. Now, I'm pretty intelligent (or so I'm told 😉) and quick learner. I'm wondering if I educated myself on the proper techniques, if swapping out batteries on the two MacBooks would be something that is achievable by myself even though I've no experience doing such a surgery. Has anyone any advice or has done said operation and can tell me how difficult it is going to be? Am I being naive in thinking that its something a Chef like myself is capable of doing or am I going to ruin my fav write electronic and be forced to buy a third Mac book in 2 years? Thank You in advance for your help! Happy New Years!!!
