When it comes to batteries.

Due to the battery fire issues (google that) the only correct answer is to get Dell batteries made for the model in question.

But there are other possible fixes. Is the Dell BIOS current? I don't tell folk which version most of the time. You check at dell.com using your service tag.

-> As I read your post a second time there's another problem. If you swap batteries the battery calibration might have to be done. This would be a pain and another reason why I don't suggest that.

Re: battery

If you mean 14.8V 40 Wh I shouldn't do it: it's a higher voltage and may very well damage a lot.
If you mean what you wrote (14.8 Wh 40Wh), that's impossible. A battery can't have 2 different capacities.
