battery has 12.8 volts...but no cranking power
If you have a fully charged battery and it drops below 9V while cranking it is toast. 12.8V is not good for a fully charged battery either. A fully charged battery should show around 13.5V.

Batteries, current, and Ohm''s law
A copper wire has a length of 160 m and a diameter of 1.00 mm. If the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated.
Lead Acid Battery Voltage Chart: The Voltage Level Differences
During the bulk stage, the battery is charged at a high current rate until it reaches 80% to 90% of its capacity. The absorption stage then follows, where the battery is charged at a lower current rate until it reaches 100% capacity. Finally, during the float stage, the battery is charged at a low current rate to maintain its full charge.
