Even if you mess things up, it is more likely that the battery will stop working than you will actually be able to harm your laptop. The biggest problem I see is how you will physically mount the extra cells to the battery so that you can still plug it into your laptop.

It will take your laptop longer to charge up (as the electronics are going to limit the charging current as if it still has 6 cells instead of 9) but that actually means that you will be charging each cell slower than normal, so they won't get quite as hot when charging. (They also won't get as hot when discharging, because each cell is providing less power at any one point in time.)

I have a doubt that it will harm ma laptop...so please clear ma doubt.....i have Dell Inspiron N5010 Laptop Its okay that we can change the cells of a laptop battery,
but can we increase the number of cells in parallel to give long backup time with same output.
eg:
a battery of 6 cells with 11.1V at 4400mAh
increased to 9 cells with 11.1V at 6600mah
the output will be same but the work hour will be increased.
I have a doubt that it will harm ma laptop…so please clear ma doubt…..i have Dell Inspiron N5010 Laptop

When I replaced my cells I had to do full charge/discharge cycles 5-7 times, and my chip gradually learned about the new capacity. If your chip is set up so that it will only allow capacity to go down (and never "grow") you will never be able to get a good capacity measure on your new battery. Hopefully you will be able to modify power settings in your OS so that the OS does not shut down automatically when the battery (falsely) reports a low reading.

(original works with 1 hour on full brightness). My problem is that the battery bar show 0% after only 12 minutes! and if I shutdown when batt on 0% the computer do not open again, just until I plugged it again. Maybe when the batt is on 0% the chip on the batt do not let the computer to start. I've tried to charge it to 100% and discharge it fully (in linux) so the computer shutdown in a moment with no hibernate, but it didn't calibrate my batt. Now I don't know what to do,when I want to use the computer I have to: 1. charge it full. 2. open on linux 3. wait 10 minutes to discharge to 0% 4. restart to win 7 and have about 3 hours of working on 0% with no time bar. Do you have another solution? Thanks! Hi Jay,

Also you should know that some batteries are not easily refillable due to their control electronics not accepting new cells. For tools you will need some screwdrivers, a plastic separation tool (plastic prybars, blade, dremel with saw blade, etc) plus a soldering iron. (Ideally you'd have a li-ion welding machine if you plan on doing this a lot, but they are more specialized.) Jay You can do it, but it will take some practice and learning before you get good at it.

I Live in a city where about 90 % percent poeple purchase usde loptop computers, which usually imported from European countries. there model also used to be out dated , in which the majorproblem comes with batteries, which literally do not provide sufficient back up. I have very much interest in this repairing work, and I want to learn it properly. therefore , I need your kind advice. If I start learning this repairing work, can I do? As I have no experince indeed in this work. And for the purpose what exact tools are required for my workshop? Looking forward for a positive response. mashalkhan28@yahoo.com Dear Jay.
