My aftermarket x220t 9-cell battery just arrived, it's good quality and gives me almost 4 hours battery life! (compared to almost 3 with my old broken official lenovo battery)
It's also about a centimeter wider, meaning i now hold the laptop entirely by the battery. Thankfully it's robust enough that it doesn't even flex.
