Question battery voltage. does it affect laptop

[mk227]

I have a Dell Latitude E7440. My current battery kind of sucks.. it is 34Wh, 11.1V, 2950mAh and only last around 3 hours (not good enough for school) . Looking online, I have found a few different batteries but most of them are less than 11.1V. I am also pretty sure its a 3 cell battery but idk how to check.

My question is: Does the battery voltage/cell have to remain the same? If it doesn't, would a lower battery voltage affect computer performance in any way? (i like to play games and would rather still be able to play them..)

Thanks

Yes the voltage and current must stay the same. The capacity of the battery can change though.

So therefore, i can change the watt hours and mAh but voltage must remain 11.1

yup
