Voltage isn't really an indicator of Lithium life. The more shagged the battery the quicker it will charge and sit with an elevated voltage. They just behave like a much smaller capacity battery with the same voltages. They just charge and discharge faster.
The only way to get a proper indication of life is a discharge cycle test.
