    Re: portables pageant

    by wear i was referring to how much of the original capacity the battery can still hold... that hw monitor was reding was calculated from the capacity reading... i did the math, my wear was <1%, so it rounded down. to settle it, i will give a screen shot of my old battery:



    so the sensor does exist.

    for the new one:

    well, it gets the same battery life as models with the same battery did new.

    my old battery did have screwball things with the battery life meter. (it would say 0% for 10-20 min). so some $$$ maker chip may have been in it. however, the fact the wear gauge in the battery went from 4 to 5 and back to four and now to 5 lights tells me it is not a simple cycle counter... it really was measuring how much the cells were reading. my guess was a fishy % of charge gauge but a real wear gauge.

    i read in a thread around here that refurbing your own batteries only saves $5 off a new battery... so you would have paid out the a** had i refurbed the old one. that, and now I have 2 batteries I can use... I may buy another battery from that lot since this one seems to be doing nicely.

    one last thing:

    my original point to stevo was that the particular batch I bought from produced a good battery, and since it was a massive lot that it came from, that it may be worth buying into. I know NOS batteries are a slight gamble... had it been an older model, then i might have considered refurbing my existing battery. I should have been more clear in my original post...

      How old was that thread?
      - I hadn't looked at replacement cells for a while and from what I can tell when I looked yesterday the price is about 1/2 [or less] what it used to be.
      - That might be enough of a price drop to make it a realistic option.

      Another tricky thing is that usually you need tabs welded to the ends of the cells and many don't come with them.
      You can solder them on but you risk degrading the cells in the process.
      [The proper tool is a kind of spot welder which naturally costs a bunch.]

          Very common that the battery gauge gets out of sync with actual battery life, especially as the laptop gets older. I have had batteries that read 0 for like an hour. Nothing malicious.

          Ebay batteries are OK. You can get a bad one so test within the first few days. If ebay cost is 1/4 of an OEM battery then you're better off gambling on it. Maybe not so hot if you have a corporate customer that depends on you but for home users its fine. I order from china, if they want me to send something back I tell them to stuff it. Postage is > than item cost in most cases. Just threaten them with negative feedback.

            i skip the chinatown batteries... i do not trust the quality/safety. I had a place send me 2 defective batteries in a row.. they would not charge... a place downtown tested it for free, it was defective. almost like they used non-rechargeable cells... i even have seen pictures of them catching fire... I have seen what china knockoff notebook adapters look like internally (lead dummy weights, no ground, crap caps, poor heatsinks, pure garbage)... I doubt the batteries are any better.

              I'm saying goodbye to my D400 in a few weeks. It'll be going to a girl who just started university and strapped for cash to buy a laptop. I couldn't think of a better way to give it a new home. Just got a new battery for it as well. However, I'll be keeping the D-bay drive for my replacement Latitude XT tablet laptop!

              Don't kick me when I say this, but I've installed Vista basic on the D400 for her because y'know... girls like to be fashionable. XP is out-of-fashion as novice people like to put it, but I'll stick to XP on my own computers.

              The D400 was replaced with a Dell Latitude XT tablet/laptop.
