I got an Acer Aspire 5100 and I just bought a new battery (after the stock battery just died yesterday). But I saw something after buying and I'm wondering whether it's really important or not.

My stock battery was a 6-cell 4000mah 11.1v and the new battery is an 8-cell 4800mah 14.8v . I know that 8-cell and 4800mah is okay, but what about the 14.8v instead of 11.1v?

The battery description says it's compatible with my laptop model (AS5100, model BL51), but the voltage difference makes me wonder.

Will the laptop only take what it needs? Or will it be getting 14.8v straight in the brain? I know that my wall plug claims to output 19v, so logically I'm thinking a higher voltage battery shouldn't be a problem. Am I correct in thinking this?

Thanks in advance for your answers!
