A listing page on the Amazon website claims to be selling battery replacements for the yet-unannounced, yet-unreleased HTC Vigor rumored for Verizon Wireless.

The Amazon page shows the battery capacity rated at 1,620 mAh, which is definitely bigger than the one on the HTC Thunderbolt (also on Verizon), which the HTC Vigor is supposed to replace when it comes out this October 5. Other sources claim the HTC Vigor release date will be on October 13.

The page also lists the battery’s part number as 35H00168-02M.

We are not certain about the authenticity of the Amazon listing, though, and it would be best to remain skeptical about this. And, although a 1,620-mAh for the HTC Vigor ought to provide enough power for the device, we have yet to see how the battery performs under real-life usage.

With LTE radios on board the HTC Vigor, the Android handset is going to surely need a lot of juice, especially since it also sports a dual-core processor.

The HTC Vigor is rumored to be renamed into the HTC Thunderbolt 2. Other reports claim a different rename: the HTC DROID Incredible HD (owing to the HTC Vigor’s striking resemblance to the HTC DROID Incredible).

According to reports, the HTC Vigor will be bearing the following specs:

  • 4G LTE connectivity on Verizon
  • 4.3 WVGA display
  • HD resolution (1280×720)
  • 1.5-GHz dual-core processor
  • 1 GB of RAM
  • Android 2.3.4 Gingerbread
  • 8-megapixel primary camera with dual-LED flash and 1080p HD video capture
  • 1,620-mAh battery pack (with wireless inductive charging)
  • 2-megapixel secondary camera
  • Mobile Hotspot
  • 16 GB internal storage
  • 32 GB external storage (class 10 microSD card)
  • Beats Audio technology
  • Beats by Dr. Dre earbuds

Undoubtedly, the rumored HTC Vigor specs look awesome, and it would be a shame if HTC provided the Vigor a battery that, er, lacks vigor and that performs just as terribly as the one on the HTC Thunderbolt.
