"any input /experience from anyone"?
Having read many similar posts from lots of people reporting the same issue you shared, I purchase/use only Sony branded optional high capacity batteries in my Sony (HDR-HC1, HDR-FX1) and Canon branded optional high capacity batteries Canon (HF S100) and have never had a problem.
I would return the battery to Best Buy for a full refund. "Should work" but does not. They owe you your $ back.
