Battery internal counter reset - Latitude D830

You can cover up the symptoms with a counter reset - but you don't know the chemistry of lithium batteries at all, if you think they're good for ten years.  They're good for about 2-3 years or 300-500 charge cycles, whichever comes first.  The battery pack needs to be replaced (and discharging it to zero will simply hasten its demise - that, along with heat - is the primary killer of lithium ion batteries).

Before proceeding with the attitude - at least have your facts correct.

The Toyota Prius doesn't use lithium ion batteries precisely because Toyota isn't convinced of their long-term reliability.  It uses now, as it always has, nickel metal hydride batteries.  Yes, the new Chevrolet Volt uses lithium ion batteries - but it has no track record (the track record of the Toyota Ni-MH batteries is very good, on the other hand - having been well proven over the years).

I'll let someone else answer your question - you're not going to listen to an answer other than the one you want to hear;  it's clear you're not interested in the truth - nor in facts.

I'm sorry if I didn't make myself clear.

I don't want to discuss whether my battery is actually dead or not. All I want to know is how to reset charge counter that is built in Dell battery pack.

P.S. You are right about the type of batteries used by Toyota - I mixed them up in fact with Volt, my mistake, I'm sorry. But it is not what I would like to discuss here.

Or let me put this another way.

Let's suppose I replaced every cell in my battery pack with new ones, bought on Ebay, dismounted from battery of exactly the same type - I just replaced cells, leaving the old chip. The chip still says my battery is old and needs to be replaced. My question is:

how can I reset internal charge counter in Dell battery pack?

Come on, there should be an easier (cheaper) way. If this is sensitive info for Dell, please write to me directly and I promise I shut up.

Any trick with BIOS, key combination? Battery has at least 5 pins - maybe it is enough to short, for example 2 with 3? I just don't believe there is not a backdoor left.

EDIT:

ejn63, I give up. I know I should buy a new battery. But I'm also pretty sure you know the answer to my question - I promise once I reset this counter, I buy a new battery :)

ejn63 doesn't seem to know the answer - instead of writing elaborates on Lithium batteries you should've just simply say "I don't know".

So, how can I reset internal charge counter in Dell battery for Latitude D830?

I know many people have this problem with Dell "smart" batteries, see this: http://www.west-wind.com/weblog/posts/365.aspx

I also found some information on battery recalibration, particularly this: http://ftp1.us.dell.com/diags/R66243.htm#s2

Here is a question to Dell - can I use any of these tools (that Dell provides, link above) to recalibrate my battery in Latitude D830?

PLEASE ANYONE REPLY

I'm also looking for an answer to this. Have a Precision M6300 and the battery died ~1 year ago. Replaced the cells today with new ones, it still runs like the old cells.

This is simply amazing...

Too bad I can't use the tools you linked to; the batteries are incompatible with mine.
