With your volt meter, touch the positive battery with the red wire and black to ground (neg, ) on the battery. With the engine off you should have a reading of anywhere from 12.2 to 12.6 volts. That is good. With the engine running at high rev's you should have a reading of any where from 14 to 14.5. When you charge the battery with a 2 amp charger it will take several days and the charge level will go up to 14.5 or so volts.

How do you measure the level of charge in a battery?
you put a volt meter on it
Battery will not charge on your 1986 v65 magna?
First, make sure the battery is good. Check the water level, then check the voltage. Must have more than 12 volts on the meter. If not, charge and check again. This will ensure that the battery does hold a charge. If all is good, then, with the engine running, check the voltage at idle, should have around 13 + volts, and at 2000 rpm, should have around 14 volts. If not, 2 things, the voltage reg. or the stator will have to be replaced.
1998 crown Victoria engine wont turn over?
First check you battery. Use a volt meter must have more than 12.2 volts, if under 12 volts, charge or change battery. No volt meter, then turn on your headlights, if good, then check shifter, in park and in neutral. If no headlights, charge battery.
How can tell your battery need changing?
Your question needs clarification. Car battery, Cell phone battery, camera battery, etc. Question was posted in car batteries category. You can check it with a digital volt meter car not running. Set the meter to 20 volts DC. Here is what you will see. 12.6 volts = 100% charge 12.4 volts = 75% charge 12.2 volts = 50% charge 12.0 volts = 25% charge
What items are need to check battery's state of charge?
DC volt meter, and a load tester. if you dont have one, try a NAPA store.
The alternator battery and brake light are on in my Pontiac Sunfire and now it will not crank so is it the battery or the alternator?
Charge the battery, start the car and check the battery with a volt meter. Should have over 14 volts, if only say 12.4 to 13, then change the alt. or check the wiring.
Voltage meter not showig charge with new battery and alternator and volt regulator in a 1969 Newport?
Check the ground connections. Can also be defective battery cables. Check all cable connections on the + & - cables. Also check the alternator drive belt.
Ford Ranger battery appears to be dead tried a battery charger and lights came on but clicking sound when I try to start it?
Check the level of the electrolyte (water) in the battery if possible. If it is near full, then reconnect the battery charger and charge it at the 2 AMP rate. This is known as a "trickle" charge. Your charger may have the 6 amp charge rate also. The amp meter on the charger will indicate a lower and lower reading as the battery is charging and accepts the charge. An Auto Zone can "load test" your battery for free if you can get it to one of their stores. Your battery sounds weak and needs a good charge (be patient...it takes time) or needs replacing.
Why new battery and alternator won't hold a charge when car is running?
The alternator does not hold a charge. It charges the battery. If it will not charge the battery then either the alternator is defective, battery is defective, or the connections are corroded or loose. You should read 13.5 to 15.5 volts at the battery with the engine idling. Check it with a DC volt meter. If you get less the alternator is defective. If you get much more the voltage regulator is defective.
If you charge four 50v capacitors in parallel then remove the 50v battery and hook it up to a volt meter will the meter say 50v or 200v?
If you charge four 50v capacitors in parallel then remove the 50v battery and hook them up to a volt meter the meter will indicate 50v.
How do you know if your battery is dead in your digital thermostat?
Remove the battery and check it with a volt meter.
How do you start a 1994 crown vic with alternator problems?
If the alternator is bad the car will still start. You just need a fully charged battery. Once running then you can check the charge rate from the battery with a volt meter.
