          Battery is probably crap. It is a common issue. Check with a fresh battery from a supplier that will take it back if there is an issue.

          Remove the battery and post the same voltages.

                  Most batteries for A1425 available on the market are garbage.

                      Can you check what is the voltage of the cells ? Sometimes the laptop battery chip gets locked due to worn cells or over discharged cells (battery stored for a long period). The PFF (Permanent Failure Flag) is set and nothing can be done with that battery unless you unseal the chip and clear PFF.

                      I usually repair laptop batteries in my free time. If you want to open the battery I could guide you how to try repairing it.
