I purchased mine at the Verizon store. The newegg link actually looks physically different than my battery. However, according to this forum post it appears to be the right battery. Rezound battery for Thunderbolt and htcpedia shows the part number as Mnfg Part #: 35H00168-02M as well. Looks like that's the right battery. Good luck, at $23 it's hard to pass up!
