    HOW TO REPAIR LAPTOP BATTERY ?

    I´m really thankful for your principal instructable, but I´m as wellnot getting the principal subjectivewise confusing way of your explanations... ?!? I´am not critisizing your efforts but I´m not too stupid as well... *;O)I never did what you are suggesting, I´am not an electrician guy but have a basic understanding of how things are working here, SO I assume there are potentially dead cellsin the LT-battery, which are going to be replaced. In my naiv way to look at the projectwhy don´t one just buy new cells (18650 cells ?!?) and substitute them with the old ones...?!? Further more- Why buying an old dead laptop battery (the exactly same type "I" have or just any LT-battery type ?!?)from laptop repair shop?!? Because it is cheaper to harve...see more »I´m really thankful for your principal instructable, but I´m as wellnot getting the principal subjectivewise confusing way of your explanations... ?!?

Further more- Why buying an old dead laptop battery (the exactly same type "I" have or just any LT-battery type ?!?)from laptop repair shop?!? Because it is cheaper to harvest potentially old but still enough voltaged working ones comparingto totally new ones...?!?- Every LT-battery hat 6 cells...?!?- How to open them, because they seem to be almost welded. This in terms open it to obviously reuse them...Probably not efectively explainable here...- "...generally 3.6 or above volt batteries are good below this voltage are the bad ones..."I am confused: Don´t these cells have a voltage of ~ 1,2 volt (My LT-battery has a roundabout voltageof 10,8 V, 4400 mAh, 47 Wh). Ok, writing these last lines I get the impression that you mean the WHOLE LT-battery, defining the voltage, from where reparing is actually necessary...?!?- "... (don't break the parallel connection but cut the series connection) ..." This means I can not change SINGLEcells because the paralell connection has to be stayed fixed as you described...?!?
