We might need to test your product to determine the final service fee. These prices are for out-of-warranty service. But this doesn't state that the battery will be replaced necessarily. They list a 'Battery Service' for a 2015 15' rMBP as costing $289.

The alternative would be to get Apple to do it. I'd also then need to swap the battery myself. So if I do it myself it'd cost about $200 AUD for the battery, then I'd need to source the solvent myself. and I'd prefer get as close to the original battery capacity as possible so would prefer to opt for the iFixit battery. and of course, I can't buy the solvent separately. Macfixit are another mob in Australia who actually have a similar kit to the US iFixit store.Д«ut the battery they supply is only 95Wh, instead of 99.5Wh. They did advise that the solvent is a mixture of acetone and rubbing alcohol, but I don't know the ratio. I reached out to iFixit and they said they can't supply the same kit that's available in the US Store.

I've already got a sufficient tools but am specifically lacking the solvent to dissolve the adhesive. Problem is, in Australia the local iFixit store stocks the same model battery, but does not supply any of the other kit. So I looked up the iFixit guide and found the relevant battery replacement kit which comes with everything required to change the battery, including the solvent to dissolve the battery adhesive. I recently repasted my CPU/GPU and noticed that the battery was just starting to swell. But periodically it say 'Service Battery'. Right now it's still showing normal on the battery health icon, iStat and coconut battery. Currently at 79% health it can go from 50% to 0% invoking an auto-hibernation, and then won't turn on again until I connect it to the power brick, whereupon it immediately shows 50% remaining. My beloved rMBP is showing battery deterioration.
