Ethical Way to Replace Battery under the Warranty

Dell E6420
So I measured my battery to CPUID and is only charging up to two-third of its manufactured capacity. Dell and Microsoft, both give me 98% and 100% charge level, which are total bogus. Those are the numbers from BIOS and Windows 7 OS, respectively.
So there is about two weeks of warranty left on the battery.
What would be the ethical way to replace battery? I am asking for wisdom here, because I somehow feel that I deserve a replacement, but I was rejected already. I know what I need to do get it replaced, but I do not want to lie or cheat. Or you can convince me that I am being cheapskate.

 

Shut down your notebook. Then immediately after pressing the power button to switch it back on, press and hold the "FN" key until you see the message that you're booting into diagnostic mode. Diagnostic mode will test your hardware for defects or problems, and after about 5 minutes of testing, the initial quick test will be completed. After it's complete it will show you some statistics on your hardware. One of those stats is "Battery Health" in a percentage. If the percentage is low enough, Dell will replace the battery under warranty. I usually have them replace mine at 75%, and they have never given me any trouble.

 

Keep in mind that batteries are covered only one year under warranty, regardless of the system's warranty.

 

Thank you. I just simply asked again and they said yes.
-Thank you for that quote: "Never give up. Simply transcend the situation. Problem solved."

 

Dell sells 3 year warranty batteries for a considerable sum. Yes if you don't buy the 3 year warranty battery, you only get 1 year on the battery on the standard battery.

 

They sell 1yr 9-cell batteries and 3yr 9-cell batteries. The 3yr one has a lower power rating, but is definitely worth the money. I'm reading minimal wear and not losing any major amount of runtime.

What this means is:
- a 3 year warranty built into the product means the quality has to be good, otherwise they'll be constantly getting returns (costs them money),
- a 1 year warranty built into the product means they probably cut corners to save on costs... and you'll probably have to buy a new one 1-2 years later in addition with having to deal with bad performance, battery disposal, etc.
- a 3 year extended warranty on a product designed for a 1 year warranty product just gets you a few replacements before the warranty goes up.

The annoying thing is that this is probably the result of matching the competition and driving the costs down, since many companies do this.

 

You can try do a calibration and see if it make windows or bios show real capacity.

Off topic/

Would people really send in their battery for replacement? I mean how do you live w/o a battery on a laptop?

It's just too inconvenient imo. Correct me if they send you new w/o getting the old 1.

 

You don't need to send it in if you have on site or Pro Support, Dell will overnight you a battery and you put the defective one back in the box.

 

You could try to call dell... They've been nice to me...

 

^This.

I've requested one at 5PM and at 11:30AM the next day FedEx is at my doorstep. Takes 2 seconds to swap out. Put the old one back in the box and hand the package back to the FedEx driver for return.
