Answer to: Battery tear-down and refurbishmentWow, Arsingenia, thank you. What you have stated is clear and lucid, and you have given me real reasons to pause on grounds of safety alone. What I will now consider doing is to perhaps look around for someone more competent who has done this before, provide him with the quality cells after he has opened the pack, get him to connect them up and possibly see everything as he does it if he allows me (!)......after, of course, ensuring the exercise is worthwhile, instead of buying a replacement at ruinous cost. I live in the Far East, and I know there are people around who do this kind of thing. I just need to find a "reliable" guy. Am more than a tad disappointed.....I like tinkering around and was quite excited about the project, but I admit this may be a bit beyond me for now, with its low margin of error. In any case, I am sure our exchange here is not a waste. It should be of help to relative novices like me before they decide one way or another. Thank you once again.
Answer to: Battery tear-down and refurbishmentArsingenia, Thank you very much for the information. Much of the theoretical aspects have been clarified. But your reply does raise more questions for non-highly technical people like myself who simply want to know the practical aspects on how to ~ a) Open the battery case of the Dell Inspiron 6000 6- or 9-cell battery pack without excessive irreparable damage to the plastic case, b) Replace the 6 or 9 cells inside with quality cells and connect it through the "battery controller", c) Ensure that the battery controller still actively/dynamically holds the volatile memory/software to control the battery pack and has not completed its specific number of hours of usage and shut itself and the battery pack down, d) Re-program the volatile memory of the battery controller with software off the internet, e) Possibly make a preliminary open-battery-case test of the battery pack with the new cells to ensure connectivity and controller activation, f) Close up the battery case. Though my Dell Battery Module Rechargeabl...
Answer to: Battery tear-down and refurbishmentThe fact remains that battery packs, original or substitute, are mighty expensive, and there is no guarantee how long the substitutes might last, since there is no way that one can figure out the manufacturer and quality of the cells inside the sealed battery pack when buying it. So it would perhaps be worthwhile to refurbish the original Dell battery packs if at all possible. Is there anyone who has been able to open a Dell Inspiron 6000 6-cell and/or 9-cell battery pack and re-close or seal it adequately, and can give or has given precise illustrated or video instructions on how to do so on YouTube or elsewhere? Replacing the depleted cells with fresh ones like Sanyo (best, with highest mAh) inside the battery pack would be a relatively easy project provided one is careful with the procedure and polarity. But what is worrisome is that despite doing so, I have been given to understand that there is a special electronic circuit in the battery pack which is intentionally programmed by Dell to block the PC's ac...
