I don't think anyone can say for sure, my guess would be Yes.Do you know if after battery goes dead can we still use them fine with the power plugged into a wall unit?
If you have an MBP with a completely discharged battery where it's shut down, switched off and tells you the battery is dead when you try to switch it on, and if you plug that in then it'll start up and work correctly almost immediately.
So it would look good for working with a dead battery.
I think it's hard to say how long they will last from new now because they are different to the old ones, but it's always been fairly easy to get at least 7 years out of them- including the latest OS
My iMac lasted 11 years and was still working really well and fast when it died- video card
This MBP is 4 years and feels like new but I did have a repair and they also replaced the battery.
But I still have a 7 year old Asus that has regular use- no battery.
My sister is still using two old Macbooks and the oldest is at least 15 years to my knowledge and one of my colleagues brought a clamshell model to work a couple of years back!
