My Macbook Pro battery died

First it would get down to 10-20% capacity then the Mac would suddenly shut down.

Then eventually it stopped charging all together. I tried resetting the SMC. After this, the battery charged once but when it discharged, would not charge again.

So I bought a new battery for $140 on eBay. I calibrated it straight away.

1. Charge to full
2. Wait 2 hours
3. Drain to empty
4. Wait 5 hours
5. Charge to full

It’s working fine now. Does anyone need a shiny aluminium paper weight?
