Early 2009 uMB 2.4 CPU Battery Question

[Wicked1]

When is the normal amount of battery cycles where the battery should be replaced. I currently have 176 in 7 months, even though CoconutBattery states my MacBook is 9 months old, I did not buy it until February 2009 and it was brand new.

I used to get a solid 5 hours but now I am closer to 3.5 what does Apple consider normal for this model and will they replace the battery if I ask them to, I am just wondering what everyone's experience is with Apple batteries.

The battery is considered a consumable part, so Apple is not under any obligation to replace it if it is considered to be within expected tolerances.

From Apple's website:

For Apple notebooks with removable batteries — such as previous generation MacBook and MacBook Pro computers — a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

Typically if the "System Profiler" says "Condition: Good" for your battery then it is within expected tolerances. If it doesn't say "Good," you are within your right to ask for a replacement since you are within the computer's warranty, but otherwise you should purchase a new battery if the drop in capacity is unacceptable to you.
