Your charging voltage is good enough, ideally it would be 14v but over 13.5v is satisfactory.
However, 12.7v at rest is borderline.
Also, battery voltage needs to be measured at the very least 30 minutes after charging otherwise the reading will be inaccurate.
Charge it, leave it an hour then measure the voltage. If less than 12.8v consider buying a new one.
