I'm doing a project with a laptop, but the battery is dead. Now the new case I'm putting it in has way more space than the previous one, so I was wondering if I could rebuild the battery following the instructions here. Also, could I do, I don't know, 3.6v cells at 2200mAh to give this a little bit of better battery life? Or could I just wire up more batteries in parallel to achieve better battery life? As I said, there's quite a bit of space in here.
Thanks!

Re: Rebuilding a laptop battery?
Swap the cells over EXACTLY the same. Never go higher in voltage, or lower. The only thing you may go higher in, are the milliamps.
If there are 7 ni-cad cells at 400 mah each, you MUST replace them with 7 ni-cad cells at 400 or greater milliamps.

Re: Rebuilding a laptop battery?
As long at the voltage (in my case 10.8v) is the same, I could use any combination of voltage/current of cells right? What I remember from physics was cell in series = increased voltage, cells in parallel = increased current. Could I do 2x7.2v cells at 2200mAh, and 2x3.6v cells at 2200mAh? Or is it bad practice? I'm seeing if I understand you properly

Re: Rebuilding a laptop battery?
Hmm... That reply is a little confusing.
Current and Voltage are the same thing, but when or not active.

Batteries in series, increase voltage.
Batteries in parallel, increases amps.
What does the label on your current battery read?
