Two possibilities:
1. the gauge is poorly calibrated. Check the actual charging rate using something a little more accurate.
2. If the alternator is actually over-charging, it's a regulator problem. The regulator is INSIDE the alternator and controls the rate of charge.
Try the lower section of engine - follow the + battery cable
A battery can show full charge but it also needs the right amount of amps to turn your car over. Even if your battery is at full charge and putting out all the amps it needs you could still have excessive resistance in your starting electrical system. If your entire starting electrical system is good than you could have mechanical problems in your engine that are making the engine much harder than normal to turn. It could also be that the bushings on the starter are worn, causing the starter to drag and not spin fast enough to start the engine.
The battery has nothing to do with the power of the engine. Now if you are referring to starting power then some batteries can show a full charge and still not be able to start the engine. Remove the battery and have it tested for free at almost any auto parts store that sells batteries or Walmart.

12.5v if the engine is running it will show between 12.5 and 14 volts. if the engine is off anywhere between 12 and 14 volts is normal.
Check the battery. If there isn't enough of a charge in the battery it could be a faulty battery or a faulty alternator. If you have a meter, test the voltage across the batttery terminals, it should show slightly over 12 volts and when you attempt to start the engine it should not drop more than 1 or 2 volts. If that's the case, have someone help you jump start the engine and take the vehicle to a shop or to an auto parts retailer who can thoroughly test the charging system for you.
For the 5.4 liter V8 engine in a 2001 E-350 the owners manual shows that the optional battery is 750 cold cranking amps ( they also show that the 6.8 liter V10 engine has a standard battery that is ( 650 cold cranking amps ) and the optional battery is ( 750 cold cranking amps )
Just for show, and to build up speed and engine heat.
Please clarify what you mean by "crank up". Do you mean that the engine won't crank when it's cold? If that's the case it might be a battery problem. Sometimes a battery can produce enough current when it's warmer but the temperature drops, the chemical reaction will slow enough that it doesn't make enough current to crank the engine. Have the battery checked. When a battery gets to that point it is weak enough that it will show up on a routine test.
Yes. Battery chargers like those used in phones and cameras do not show how much charge is in the battery, but simply show when the battery will accept no further charge. The capacity of a battery to accept a charge becomes reduced through age or other factors such as repeatedly allowing it to fully discharge. It will charge, but not to its full capacity. Thus, while the charger may show that the battery is full, there may be so little actual charge that it goes dead immediately when the device is turned on.
There is a power icon on the taskbar. It shows whether the computer is plugged into the mains or on battery power. If you hover your cursor over the power icon, while it is running on battery power, it will show as a percentage how much battery life is left (along with an estimate of how much time you have left before the battery dies).
It should be in your engine compartment , on the battery side , near your power distribution box - it will show EEC TEST on the plastic cover
