If the car won't start but the battery is good, check the timing belt. The car won't start but the battery works well while starting it just turn over and will not start but the car turns over a lot faster than normal. If the battery works fine the possible reason why the car won't start is the timing belt.
How to troubleshoot if the car that won't start
The first thing to check is the battery, open the hood and locate the battery. Using a multi-tester check the battery voltage, the battery voltage should be at least 12.4 V, if the battery voltage is good next to check is the battery condition. Check the battery terminal if there is a presence of a cruddy-like substance on the battery terminals, if there is a presence of this substance, then that is the reason why the car won't start, it is because that substance prevents the flow of current from the battery to the starter. Now if the terminal is in good condition and the battery is good and works fine then the battery is not the problem.
Now start the car, if the car turns over faster than normal then this is an indication of a problem that has something to do with the timing belt. The function of the timing belt is to make sure the valves in each cylinder are closed during the combustion inside the engine cylinder, it is necessary to provide compression. If the timing belt is not functioning properly and has a problem like if the belt is broken, there will be no compression inside the engine during the compression stroke and will cause the car not to start.
The car that is not starting with a good battery usually a broken timing belt or lack of compression is the main reason.
