Macbook pro battery cycle count

I received two days ago a new genuine Apple battery I bought from eBay for my MBP late 2008. I couldn't check the cycle count at the beginning since I had to do a new Snow Leopard installation, but I have been charging the battery since almost 2 days. Checking now with System Profiler the cycle count, I see:

Cycle count: 4
Condition: Normal

Are those values expected for a new battery?

TIA.

At that rate it won't last very long at all. Less than 2 years.

Is there a way to know if the battery I bought is really genuine? It has the Apple logo, and physically it looks like a genuine one, but the wierd thing is that the serial number displayed in the system profiler (see below) does not match the one that is printed in the back of the battery: W010220AJ6G1A

Could someone confirm if the two serials should match? Any help appreciated.

TIA.

Since it is very easy to access to the late 2008 MBP battery, I need the help of someone who has it to check if the serial number printed in the back of the battery is the same as one displayed by the system profiler application.

Any taker?

TIA.

No, if you're buying a new battery, the cycles should be zero when you first get it. It is not normal to buy a new Apple battery with cycles already on it. It is possible to buy a new Mac that may have a few cycles on the battery from testing, but not a replacement battery.

I'm not aware of any genuine original Apple batteries being sold new on eBay; only used or knockoff batteries. I wouldn't trust or recommend any non-Apple battery, due to the number of problems reported with "knockoff" batteries. Also, there is no assurance that knockoff batteries have the same charging technology that Apple uses, involving the battery, the MagSafe adapter and the Mac's logic board.

This should answer most, if not all, of your battery/charging questions:

That was that poster's first post in the forum. They don't know what they're talking about, as it's definitely not normal.

Apple Notebook Battery FAQ
I could check the battery status only a day and after it arrived because I had to install Lion. Could it be that 4 cycles have been consumed in 1,5 days?

The ebay link I put in my first post is from someone who claims that it is a new genuine Apple battery and sells it half of its price in ebay compared to Apple's price. It has the Apple logo and the details I explained in my previous posts. I just can't explain why the serial repported by the system profiler is different from the serial printed in the back of the battery . Could it be an imitation?

The amt of posting someone does does not influence the answer's correctness GGJ. If he is wrong, then he is wrong but it is NOT because it was his first post in the forum...

Similarly, those who post alot (you and even me) does not mean our posts carry more weight

You're not going to find a genuine Apple battery at half the price. It's a knockoff.

You can also click "About Your Mac" in the Apple menu, then click "System Report", then click "Power" in the hardware section to see all your battery details.

I didn't say they were wrong because it was their first post. They are wrong, because it's not normal. The fact that it's their first post indicates that they haven't posted enough to earn a reputation for posting factual information.

It is not normal for a brand new battery to have cycles on it. Also, read the WHAT IS A CYCLE? section of the Battery FAQ I posted earlier to understand how cycles work.

You're still wrong about the battery cycles.

It was your first post. That's a fact. Your post was wrong. That's a fact. With regard to what you posted, you don't know what you're talking about. That's a fact.

Thanks, I already read it. Indeed I don't think I did 4 cycles in a day and half. When it has 0 cycles, then the Health Condition in the System Information would show "Good". My question: After how many cycles the Battery Health Condition goes from "Good" to "Normal"?

In order to argue with the eBay seller, I need to find out if you gals/guys could check that the serial printed in the back of your battery is the same as the one reported in the System Information.

For those who are willing to help, to access the Battery System Information click "About This Mac", then click "More Info..." button, then click "System Report" button. In the hardware section click "Power". In the "Model Information" subsection, you'll see the serial number and in the "Health Information" subsection you'll see the cycle count and condition.

My system reports actually the following:
Battery Information:

Model Information:
Serial Number: 6N9030A6X2VLA
Manufacturer: SMP
Device Name: bq20z951
Pack Lot Code: 0
PCB Lot Code: 0
Firmware Version: 002a
Hardware Revision: 000a
Cell Revision: 100
Charge Information:
Charge Remaining (mAh): 4775
Fully Charged: Yes
Charging: No
Full Charge Capacity (mAh): 4775
Health Information:
Cycle Count: 5
Condition: Normal

Battery Installed: Yes
Amperage (mA): 174
Voltage (mV): 12569


To read the serial printed physically in the back of the battery, you need to remove the lid at bottom of your mac. For those who have the late 2008 MBP it is very very easy, you don't need a screwdriver.

I just need to confirm that both serials match in order to argue with the seller that it is not a genuine Apple battery, because he cold claim easily that I did those 5 cycles reported by the System Information...

Thanks for your collaboration

Good and Normal mean the same thing. From the CHECKING STATUS AND HEALTH section of the Battery FAQ:
Quote:
Leopard users may see their battery reported as "Good", while Snow Leopard and Lion users will see the same condition reported as "Normal". They mean the same thing.
