Is it OK to drive a van with a new battery if the alternator should test 1340 but tested 1270?

The numbers you referenced seem as though they may be specific to an individual tester, unless you're talking about 13.40 volts vs 12.70 volts. If the alternator is only producing 12.70 volts, you'll probably run the battery down. How did you come up with those numbers?

Why is your battery not charging when you drive?
dead battery dead alternator dead voltage regulator each needs to be tested.
What is wrong 97 Mystique 2.0 has spark and fuel into cylinders turns over but won't start?
it might be the alternator, try and get it tested. if the car won't start the battery will also be dead, you could replace the battery and drive it to get the alternator tested at an autozone or advance auto parts for free.
How long must you drive a Mercedes CLK 320 after replacing battery?
If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.
Could the problem be your alternator or the battery when the check gauge engine light comes on while the battery gauge keeps moving.?
that depends on what your voltage gages says while the car is running. while the alternator is spinning, it should generate 13 to 18 volts. if that's the case, your alternator is fine. If not, you need to replace it. it won't charge the battery, giving you about 20 minutes of drive time, but the more you drive the battery like that, the more you will stress it out. if you stress the battery too much, it may go bad on you too. you can get the battery and alternator tested at most auto parts stores. many stores will even test your parts for free.
Why does the battery not charge?
Corroded or loose battery connections, loose alternator drive belt, defective alternator, or dead cell in the battery.
How long do you have to drive around to charge a car battery after jump starting a car?
You should never drive a car around for long after jump starting a dead battery. This puts an enormous strain on the alternator. Alternators are designed to keep a good battery charged, not to charge a dead battery. You can easily burn out a diode in the alternator. Jump start the engine and drive it somewhere and connect a battery charger to the battery and charge it fully.
How long do you run your car after a a car jump?
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
How do you tell alternator is bad?
The best way is to drive it to your nearest auto parts store and have it tested. You can test it somewhat yourself. Start the engine and use a volt meter to test the voltage that is being supplied by the alternator for the battery. If it is less than 13.5 volts the alternator is bad.
Will a dead alternator drain a battery?
Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.
What causes alternator battery light to come on and then off itermittently?
Can be loose or corroded battery connections, loose drive belt, or the alternator is failing.
Why do you think a 1998 Chrysler Sebring makes a flutter noise when you try to start it do you think its the battery or the alternator?
Could be starter drive or weak battery you should check out the battery first
Why is your new alternator not charging your battery?
The drive belt is not tensioned. The fuse in the line between the battery and alternator is blown. The battery has a bad cell. The voltage to the alternator field is missing from the regulator or ignition switch circuit.
