Looking for a replacement battery "Apple A1281"

Hi everyone!

My first apple laptop (Late 2008 macbook pro) is still going strong. The 2nd battery is nearing the end of it's life with 93 cycles, yes 93 cycles!!! (must have been given a faulty battery by apple when I bought a new one).

I was just wondering where I can buy a reputable battery from? lots on amazon, ebay and other websites like ifixit but i'm not sure which would be the most reliable and best.

I'm trying to avoid a cheap chinese knock off that will explode and destroy my computer basically. And one with a battery life (longevity and charge capacity) as near to the original as possible.

Here are a few I've found:

Any advice on which one to get would be greatly appreciated.

Also does anyone know why my replacement battery from apple has been so poor? See attached from profile. Gutted it is bulging and is asking me to replace it after 93 cycles!
