2015 macbook pro, battery lasts a couple of hours max now - used to be 8/9 hours. That suggests it needs a new one but is that backed up by the numbers below?
Anyone know how much a new battery would be via offical channels?

No idea. But my 2015 MBP (13inch) has a 'Full Charge Capacity' of 5775 mAh, which suggests yours is fairly well down on capacity.
Mine has only done 407 cycles though.
My ‘11 air started to last a couple of hours between charges.. the health count etc didn’t look too bad so I ended up using it on power a lot more not bothering to change it. Iirc I was on 800 or so cycles. Eventually the battery swelled overnight and the next morning the MacBook was like a beach ball!
Got an ‘apparently’ oem battery for it and fitted it, amazingly easy and the case just went back to shape and it holds about 4-5 hour charges now, not as good as original but it’s a decade old. So I’d say just change yours.
And be VERY CAREFUL with swollen batteries. Like, outside, NOW!
Does this battery need changing?

It often turns off at anything up to 90% if you ask it to do anything taxing on battery power.
