new battery..

Charge Information:
Charge remaining (mAh): 2657
Fully charged: No
Charging: No
Full charge capacity (mAh): 2986
Health Information:
Cycle count: 160
Condition: Check battery
Battery Installed: Yes

Full charge should be around 5500 apparently and the cycle count is about half way. Time to speak to a genius.. (I have no applecare).

According the the “genius” at Apple Highcross the battery I have is working just as it should. Because it is “so old” it cannot hold charges. While I’d expect some degradation this much is pretty damn stupid.
And note it says “Check battery” not “Give Apple a hundred quid for another”.
