Macbook Pro 2012 shuts down unexpectedly with good battery

My MacBook Pro 2012 will suddenly shut down when the battery level will show 58% or something similar. I have checked the health of the battery and it indicates it is normal - no need for service. I have 120 of 500 GB available. I am running macOS Catalina 10.15.5. Suggestions?

MacBook Pro 13-inch 2017 randomly shuts down My MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) has been randomly shutting down while operating. When I press the power button, it says it is out of battery even if it is fully charged. And when I plug in the charger to turn it on, there is still lots of battery left. I ran the Diagnostics by pressing and holding D at startup, it resulted in PPT002 which seems to be an indicator that my battery is fine but under a certain percentage of design capacity. My Cycle Count is 357 now as I has only removed the charger approximately once a month. It is supposed to last up to 1000 cycles, isn't it? Should I go to the store and change the battery? I am using macOS Catalina version 10.15.2. Thanks,

Sudden drop in battery capacity and sudden shutdowns Hey everybody! I'm having a little problem with my 2017 13" MacBook Air running OSX 10.14. It shuts itself off at 30-40 percent of battery charge without any notification whatsoever. I've been monitoring the battery health of my laptop with CoconutBattery and what it shows me is really weird. Its capacity dropped from 64% to 38% in one month, even though I was using my device as usual. Also there's a low charge cycle difference too. I've calibrated the battery (charge for 2 hours, drain, let it sit for a few hours and then recharge it again) three times already and the issue doesn't go away. I've reset the SMC too. I'm pretty sure it has something to do with the component giving the battery info to the OS. Because I booted Windows with Bootcamp and the battery percentage also jumped 10% or more in a minute. Is this a common issue? Do you have any idea what could be wrong? Thank you for the replies in advance. Here is the reading of CoconutBattery from the last few months:

Unexpected shutdown when using battery on Macbook Air My Macbook Air 13 inch (early 2015) unexpectedly shuts down when off the power adapter for an hour or so. If it was fully charged it will still just shut off with no warning after about an hour and I've never seen it get below 40%. It won't restart until I plug it in. It says "battery service recommended." It only has 218 cycles so it shouldn't be doing this. Must I go into an Apple store?? Or can I just buy a replacement battery and DIY?
