Why does my car battery reads 12.5 volts but won''t start?
1. The battery charge is insufficient. If your car battery reads 12.5 volts but won''t start, it''s because it''s probably not charged enough. To check, use a voltmeter to measure the voltage while the engine is running. If there is no voltage of nearly 12.5 volts, the battery is not charged sufficiently.

voltage drop when trying to start?
Just a guess, but maybe your cables going to the starter are bad. Do a voltage drop test on the cables while trying to crank. Put one lead of a voltmeter on the + battery terminal and the other on the end of the + battery cable on the starter. Do the same with the - battery terminal and the starter case. Both readings should be "0".
