Laptop battery cell upgrade

[alphahead]

Hello everybody,

I have Lenovo Y580 and recently its battery (6 cell) is not doing so well, my max capacity is around 2500 mah. So I looked around and it seems the genuine battery (6700 mah) is not being produced anymore so i thought to change the cells myself. Now my question is if use higher capacity cells, will the chip accept them? I read in a forum that there is safety fuse that could render the pack useless if blown by a difference in voltage or current.
Appreciate any help / suggestions.
P.S. attached a photo of my battery: https://ibb.co/dUFeq6

Cheers

There's usually a charge/temperature sensor in the battery case and it may balk at more current needed for charging. Your SW charge estimate may also show wrong readings. There's also a possibility of power supply being inadequate.

Thank you for your reply, so by my estimation each original cell should be around 1120 mah, and if i upgrade to 1500 mah the total would be 9000 mah more or less. The power brick is big (19.5 v and 6.15 amp), so i guess it can support that.
Anyway would you suggest that I keep the total mah the same? is there anything else that I should consider while replacing?


Tnx

Yes, there are many types of cells, with different characteristics, should try to get close to original ones.
