Can I buy a replacement battery with a different voltage to my factory battery?

post #1 of 14
Thread Starter 
The question is in the thread, really. I need to replace my laptop's battery. The laptop is an ASUS N61-VN-A1. The back of the battery says it's a +10.8v, 4400 mAh brick, meaning 48 Wh.

Do I need to replace the battery with another of the exact same voltage and amperage? Or can I buy a +11.1v battery with a different amperage?

Thanks, OCN.

no, you need the same voltage. higher amp/hour is fine.

This

Same voltage and you can get one with equal or more amperage.

So how come when I search for replacement batteries for the N61 series of laptop, I find "a32-n61" laptop batteries that are "designed for the ASUS N61-series" and they're +11.1v?

I don't doubt what you're telling me, but why would a product marketed as an N61 replacement battery be the wrong battery?

Here's what I'm talking about.

beats me, it could be a revision change for the lap top.

li-poly battery is 3.6v x3 cells = 10.8V

li-ion battery is 3.7V x 3 cells = 11.1V

Alright, +10.8v it is. Thanks a bunch! +rep

Don't get any more voltage than stock, like others said, same voltage more amps.

Think of it like this: Amperage is how long it runs, voltage is how well it needs to perform while it runs. A CPU at 11V would perform terribly(I think?), but if it's not plugged in and has a billion amps, it would run terrible as long as you want it. This is why we overclockers slightly raise the voltage on our CPU to let it perform better, but we can't select amps, because it is always supplied with the amps it needs. /terrible explanation

No, I get what you're saying. I know from my own overclocking that voltage equals power. I guess amperage is like the quantity of power, if I'm understanding you.

I got sold a compatible battery for my father's Fujitsu Amilo D1845.

THe battery they sold me was 11.1v
