IBM 600 Series Laptops and Flaky Batteries?

Rensselaer Polytechnic Institute distributed these laptops to freshman students in 1999 and almost everyone I knew in my class had this issue. Ralph Levien's page has suggested it appears to be an issue with the 'Smart Monitoring' circuitry. I'm writing this article to get the issue out in the open so IBM can no longer deny it. These batteries are expensive, and I have had to replace mine 4 times already. Can anyone who reads/maintains slashdot help or provide any advice on getting resolution for this?" I must say that from personal experience, I've wondered if this might be the case as well. I have an IBM Thinkpad 600e laptop and I've already gone through 2 batteries. The laptop is currently inactive as it must be tied to the wall if it is to be used. Has anyone else experienced shorter-than-average battery life using these laptops? Were you able to do anything to improve the battery life?

When the insurance company eventually bought new laptops, they still bought "stinkpads."

      Ok, once again I feel compelled to add something to a battery discussion.

      First: The single worst thing you can do for a normal battery pack is to run it all the way down. You'll almost certainly reverse some of the cells, which will KILL the overall battery life (one bad cell in the group will cause a dramatic shelf effect on the available current).

      Leaving it on the charger continuously is generally believed to be a bad thing as well (causing things like crystalline growth), but exercise, not exhaustion, is a good practice.

      The main problem here is that no two cells are alike. If the cells discharge asymmetrically, they'll recharge asymmetrically as well. You end up with a cell or two in the pack that is still not completely charged when the rest are. Since the voltage is still not at the peak, the charger continues dumping current in which damages the full cells. If you take it off prematurely, the cells with more charge will damage the cells that didn't completely charge.

      The problem is : as long as the cells are charged and discharged in series - this is basically unavoidable. You'll get the best cell life out of charging and discharging them in parallel. However, this is more expensive - and therefore no manufacturers use it.

      However, this is more expensive - and therefore no manufacturers use it.

      More expensive? How would you get the voltage you needed to run the machine? The chemical makeup of a cell determines its potential voltage.

      NiCd = 1.2v
      NiMh = 1.2v
      Lead Acid = 2v
      Li-ion = 3.6v
      Alkaline = 1.5v

      The only way to increase the voltage is to put them in series or double stack the internal construction but that is not any different then putting two individual batteries in series. A good example of that is a car battery, it is actually equivelent to 6 individual lead acid cells sharing the same electrolyte.

      If your laptop could run on 3.6 volts then you could use Li-ion cells to run and charge it in parallel like you suggest. Any required voltage higher then that would require a conversion process with a voltage multiplier (dc-ac-dc) which is not very efficient and probably not very practical or use what you have now which is a bunch of individual cells tied together in series to form a battery with a higher voltage. Charging and discharging circuits made these days are "smarter" then they used to be and will shut off at a level that should not reverse a cell when discharging or overheat when charging. In post earlier in this story a guy claimed putting tape over the voltage sensor leads allowed much more use out of his current battery, well that is because the protection for the battery was removed. Cells do go bad and have different tolerances, even charging as battery of cells in parallel like you suggest would still cause the same cell to fail just as quickly and lower the batteries overall capacity as each cell can not be monitored or charged directly.

At first, I was getting about three hours per battery (and I was using both bays, so it could run close to six hours). After a couple years, the cells had (I guess) degraded a bit, to maybe 2.5 hours per battery.

      That was before I installed Mac OS X (which I've been running since the first Public Beta (which really should have been called an "Alpha", but that's another topic)). The time per battery immediately dropped to about 1 hour -- it happening so suddenly must mean that the system is just more power-hungry (not cycling down the CPU, virtual memory keeping the HD (almost) always spinning, etc.).

      That much would be almost okay, I guess, but get this: while the machine is asleep and unplugged the fan runs -- it stops when I plug it in and starts again when I unplug it, all while it's asleep. Weirdest bug I've ever heard of -- I don't even know how they could have made it do that if they tried, but there it is. It's really awful for several reasons: first, it runs down the battery pretty fast while sleeping. Even worse, it increases the risk of losing power completely. I find that after it puts itself to sleep, I have about fifteen minutes to reach an outlet if I want it to recover. Still worse, I suspect that the frequent shallow cycles (as it drains a couple percent while I carry it around unplugged for a couple hours and then plug it back in) are real murder on the battery, causing it to degrade even faster than otherwise. Within a year, the older battery wouldn't charge at all and the newer one was already pretty bad.

      Since then, that one has died completely and I've tried to avoid using battery power at all, to preserve this new one.

      About the only-charging-to-98% thing: I suspect that that's actually a good thing -- something they did on purpose to reduce the shallow-cycle problem. I've noticed that mine doesn't start charging unless it's below 95% when I plug it in, but then it'll go all the way to 100% (or even 101%) -- the effect is to combine several shallow cycles into one slightly deeper one.

      The (other) worst thing is that when it dies, it does it abruptly, with zero warning, sometimes while the meter is reading near full -- usually 50-60%, but once as high as 87%.

      I'd assume that the power drain during sleep is a matter of incomplete support for such an old model, and that the newer iBooks and PBG4s would be better that way, even if X is still such a power-hog. I would have hoped the battery longevity would be better too -- good thing I didn't buy that new iBook yet; I wonder if the new 12" PBG4 is any better.

Another is to call about the warranty, even if it's out of warranty. They offered to give me a battery for half price if I shipped them the old one. Lastly, if it's under warranty they'll send you a new one and a prepaid box to send the old one back.

Couple that with a fixed number of recharge cycles (where going from 95% to 100% counts as a cycle) and you see that any time you run on batteries, you should go down to 40% and then recharge.

    Also note that the latest BIOS for the 600E won't start a recharge cycle unless the battery is below 95%, which is a good thing. IBM also recommends that you upgrade the configuration utility when you call about the battery warranty - they claim somehow the newer version is better for the batteries as well.

    notice. I've had 4 experiences recently with the
    AG's consumer affairs offices in NJ, NY, CA, and
    TX, and they ALL got me my refund/replacements
    within a month. They all have an online fraud
    complaint filing system. Hope this helps.
