A:Answer Is it just 'not recommended' to protect the profits of the corporation, or will it physically or electrically not work, or work with reduced capability?
I was willing to pay the premium for an OEM replacement. Sony has discontinued all but the smallest OEM batteries for this unit (the HDR-SR11/12) which was a top-of-the-line unit a few short years ago. Sony has now left me with potentially sketchy third-party alternatives...
I am now MUCH LESS likely to pay the premium to buy a Sony product in the future, just to be orphaned like that again. 'Fool me twice...' as the saying goes.
Beware all Sony buyers, this will happen to YOU someday too.
