MBP battery questions

[McGiord]

Hi there, I just got back my MBP (15" late 2008 2.8Ghz) from the apple store repair service, they did replace other stuff, but I suspect that they also replaced my original battery, without listing it on the list of parts repaired.

The repair requested was not battery or power related.

I don't have a record of what the serial number of the original battery is.
Is there a way to check what the original battery serial is? Is there a record inside my Mac somewhere that I could check?

I do have a new battery I bought recently.

The serial numbers that I have are:
1- battery returned from repair: 6N844049N13EB
Design Capacity: 4600 mAh
Current Capacity: 4344 mAh
Cycles: 226
Health: 94%

2- battery recently bought: 6N8430CA213E
Design Capacity: 4600 mAh
Current Capacity: 4600 mAh
Cycles: 24
Health: 100%

How can I decipher these serials?

My concerns are that the battery they gave me back has some dents and scratches, that my original one didn't have, and the design capacity mAh vs the current one.

Also what was long was the battery supposed to last as per the specs by apple for this MBP model?

Anyone?

I would suggest that if the cycles on the battery now are different (lower) to what they were before, it's probably been changed.
