Best MBP battery (extra, for travel)

[PaperQueen]

Hi all,

I’m headed to Hong Kong and need more hours on my MBP than a single battery can provide during the flight (nope, no electrical at my seat). Obviously, I could buy an extra battery from Apple, but am wondering if anyone else sells one that’s got a longer life span or is a better option?

Wisdom to share, anyone? Thanks in advance.

Bumping, as this applies to me as well. Anyone have any advice?

You didn't mention the size of your MBP, so I assumed it's a 15", but this link also has 17" replacement batteries. Fastmac.
