Looking for tablet: max battery life

I am looking for a tablet. It will be used primarily as an e-reader, but I'd prefer color.
The primary criterion is battery life, AND the battery should be user-replaceable. It should also accept a microSD card. I'm looking for something around 7". Speed is a low priority, but a screen usable in many different light levels would be good.
I did a search on Google for tablets with longest battery life, but I don't think the LG that came out on top has a user-replaceable battery.

Recommendations?

I don't remember seeing any sort of tablet that has a replaceable battery. That said, I'd go either Samsung, or Amazon. I only got Amazon as a gift, rooted it, and did a lot of stuff. Much better for me. Anyways, I don't remember is the nexus now supports SD cards....
