oh yeah, and the notebook batteryinfo is not compatible with the KR battery (as told by the representative) :lol:

The Dell battery model numbers affected by this 2008 recall are OU091 and W1435

the inspiron 910 is not in the list, its battery model is W953G, and this is an 2006 issue actualized to october 2008 for these particular models, nothing to do with dell mini. as i say before, they like to fool us around, don't play they're game.

LOL, I guess you're the guy I was talking to on dell chat. "back up time" was the word of the day, whatever that means... :|

Maybe we should run a standardized battery rundown test and post the results here.

I agree, a run-down test would help. How about setting full brightness, wireless/bt off, and rebooting into safe mode? That way there's no background apps or anything to cause variances.

I just got out of hardware chat and they agreed to send me a new battery. The rep said it should arrive in the next 2~3 business days. Hopefully i will get a 32whr and not a 22whr.

Now how did you do that? I tried, but no luck. My rep was convinced the problem is software related.

FWIW, I'm open to the possibility that there could be a software reporting problem, but I'd sure like the peace of mind of a new battery.

off course, almost 2 hours but managed to get it. 3 or 4 days he or she said, with the verbal compromise of change it again if the replacement is another KR. people, ask for that two.

keep reading the thread, many people says interesting things about how to deal with them, and the results

that last line :lol: they,re think that we're stupid or what!? :lol: if anyone get the same answer, tell them about linux reads, the 2200 and 3200mAh 8-)

Well my chat with Dell was interesting.

The rep said that the battery was designed for 24Wh and that the 32 Wh label must be a mistake. Which is crap.

Here is the interesting portion of my chat:

Agent (Sebastian_192016): "How long does you battery last , after you fully charge it ?"	
Ian Magnone: "best case 3.5 hours"	
Ian Magnone: "my friends last about 4.5 hours"	
Agent (Sebastian_192016): "I checked with the system details , your battery is doing normal."	
Agent (Sebastian_192016): "The average time before the battery goes down is 3 to 4 hours."	
Agent (Sebastian_192016): "Are we still connected ?"	
Ian Magnone: "yes"	
Ian Magnone: "alright, well its still a problem that the battery is advertised as 32 Wh and really only gives 24"	
Agent (Sebastian_192016): "It is designed to give 24"	
Ian Magnone: "then why does the battery label say 32?"	
Agent (Sebastian_192016): "Does it say on the battery ?"	
Agent (Sebastian_192016): "As per the screen shot you sent , it says that is is designed to 24 and thus is giving 24."	
Ian Magnone: "thats the problem"	
Ian Magnone: "the good battery has 32 and mine has 24"	
Ian Magnone: "the label on my battery says rating 14.8v and 32Wh"	
Agent (Sebastian_192016): "If you can check the Wear level its 0 % , the battery is not wearing out."	
Ian Magnone: "the wear level is 0%"	
Agent (Sebastian_192016): "Yes,"	
Ian Magnone: "the problem here is that the battery is supposed to have 32Wh and it only has 24Wh which is 25% less than it is suppose o have"	
Agent (Sebastian_192016): "That is nothing but battery electrical specifications."	
Ian Magnone: "if the battery is labeled as 32 it should give 32"	
Ian Magnone: "so your saying this is just a mislabled battery then?"	
Agent (Sebastian_192016): "Could be , Ian ."	
Ian Magnone: "then why is the mini 9 listed everywhere as having a 32 Whr battery?"	
Ian Magnone: "http://www.dell.com/content/products/productdetails.aspx/laptop-inspiron-9?c=us&cs=19&l=en&s=dhs"

Ian Magnone: "Power 
4-cell 32WHr Li-Ion Battery"	
Agent (Sebastian_192016): "I did check that , usually 4 cell battery dont last more then 2 hrs"	
Ian Magnone: "the dell site says over 4 hours of battery life and you say not more than 2 hours"	
Agent (Sebastian_192016): "As of now , all I can tell you is that the battery is doing good."

I hope someone gets them to fix this. Maybe I wont need an extended battery if I get the full power I paid for.

A way to try and see if the battery is just lying about how much capacity it really has is to connect the 2 versions of the battery to a consistent load and see how long it will last. I unfortunately dont have the tools with which to do that safely.

I just ended a chat session with a supervisor in support who has agreed to escalate the issue further. The chat session took over 1 hour of discussing details. Here are the pertinent highlights for those contacting Dell directly: (Please note, these are the discussion points I provided to Dell, not necessarily the viewpoints of any Dell employees)

1) Those with a DP/N starting with KR-0Y635G have noticed decreased battery life from the expected
2) It is for that reason that the OP checked the battery design charge
3) It is _NOT_ merely an issue of incorrect reporting by the battery to the ACPI
4) Those with a DP/N starting with CN-0C901H have not reported shorter than expected battery life.
5) The capacity of CN-0C901H batteries is reported by ACPI as expected to be 32Wh
6) The capacity of KR-0Y635G batteries is reported by ACPI to be 24Wh
7) The battery label states that it is intended to be a 32Wh design
8) The Bill of Materials for orders (at least mine does) state that it includes: "C050H Module,Battery,Primary,32WHR 4C,Dynapack International Technology Corp"
9) The issue is not with a single piece of software. The same values have consistently been reported across operating systems (including the dell supplied Ubuntu, using /proc/acpi/battery) as well as multiple windows third party programs.
10) The fact that the values are reported differently across multiple operating systems and programs suggests that at the very least there is a reporting problem with the battery, and thus it is defective.
11) Initial volumes of reports (here in the forums) seem to indicate that this could potentially be a widespread quality control issue
12) The nature of the difference in reported vs. specified voltages and capacity _suggest_ that this could be an issue where only 3 cells are operation in what is supposed to be a 4 cell battery

On further reflection, other important items to note if you contact dell:
13) The values reported by the battery to ACPI are used for power management, and thus even a reporting problem is a serious defect of the battery
14) Given that this is a Lithium-Ion battery, and said technology can be volatile if a cell is to short circuit, this is potentially ALSO a major safety issue. Because it is possible that 1 cell has already short circuited or been damaged. Reference the following: http://en.wikipedia.org/wiki/Lithium-Io ... technology

Add me to the list of KR batteries. The 2 Dell Mini's I have both have them. Yuck!!

I just an email to my Dell Rep. I'll see what comes out of this....

We'd have to make sure the results can be compared... screen brightness at max, volume at max, same application, test to same threshold (say 5% remaining time causing system to shut down), battery charged to maximum before the test, only relatively new batteries to be compared, etc. Not aware of any standardized testing applications though. Somebody have a suggestion? I presume Windows XP software would find the most users...

is a good proppose, but luckily they're people that had the two batteries, and they tried both in the same system. the differences are obvious, objective and subjectively speaking. anyway, if someone get that peace of software, i can run the test and post the results as a definitively proof, another one off course :lol:
