-> To understand more about the issues with batteries, look back a few years at "laptop battery fires" and for a time it was a real problem. The makers (such as the one under discussion discovered that batteries from other than them could be problematic so they designed in more safeguards as well as not charging batteries that could not be identified.
Some will call that a "nanny mentality" where folk don't take responsibility for their actions. That is, if a non-sony battery went up in flames on a Sony charger, some folk would blame Sony rather than their own action.
The result is that some batteries will fail the ID check and won't charge.
