Trouble calibrating replacement MacBook battery

[MattBaker]

I just bought a replacement battery for my two-year-old MacBook. I can't get my computer to charge it beyond 75%... what am I doing wrong?

I've done three complete cycles of charging 24 hours, then discharging completely, then charging again.

I just finished a 36 hour recharge with the computer turned off. Now I'm looking at Coconut Battery, which says:

Current Battery charge: 3890 mAh
Maximum Battery Charge: 5344 mAh
Current Battery Capacity: 5344 mAh
Original Battery Capacity: 5600 mAh
Battery Load-Cycle: 4
Age of your Mac: 28 months
Charger connected: Yes
Battery is charging: No

What's the trick to get this thing fully charged?

Thanks.

No trick. I'd take it back and get a replacement.

It appears borked.

Time to replace the replacement...
