Want to save a quick $16 on the Seidio Innocell 3500mAh extended battery for the HTC EVO? Then buy it for $53.96 from Amazon
Seidio is still selling the battery for $70, so Amazon's newly lowered price isn't part of an across-the-board reduction or anything like that. In fact, it wasn't too long ago that the online retail giant had it in stock for $63. Considering that Sprint's new extended battery retails for $55, paying a dollar less (plus no tax or shipping, depending on where you live) for more capacity isn't a bad deal at all.
Seidio's Innocell has been around since July, but here are some pics just in case your memory needs to be refreshed.
