Yes.
I've definitely seen this many times before.
Our Battery Super Reviver can address most batteries that suffer from this.
There's probably one not too far from you.
Send me a message if you would like detailed info.
The cause seems to be a glitch in the Battery Management System (BMS) likely caused by a brown out or blackout.
Then the battery does not charge properly ( for some months )
Eventually the battery depletes.
The work around ( before you get to this point ) is to put it on a timer.
That way the charger re-starts ( say daily ) and runs for ( say ) an hour.
Thus the battery never gets to deplete.
