What voltage should a stop/start battery read when fully charged?
Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.
Can a start/stop battery be charged?
If your vehicle has Stop/Start Technology, it will be fitted with either an EFB (Enhanced Flooded Battery) or an AGM battery (Absorbent Glass Mat), so you’ll need a smart charger to charge these types of battery safely.
Is 12.7 volts enough to start a car?
However, what is the minimum voltage to start a car? There is no exact answer to the question. In the standard state, a fully charged battery should show a 12.6-12.7V. Many experts assure, you need to wait at least for an hour, then it should drop from 13 to 12.7V.
Is 11.5 volts enough to start a car?
The normal voltage needed to start the car begins from 12.6 volts. At the time of exploitation, this parameter is between 13.7 to 14.7 volts.
How does battery drain when turning key to ” start “?
Instantly upon turning key to Start, fully charged battery drained to less than 4 volts – either of two batteries. Instantly! With everything off and all fuses and circuit breakers removed, get +9.5 volts between negative pole of battery and ground at alternator mounting frame. Same with either small wire disconnected from battery post on solenoid.
Why is there no power when the key is turned?
When that dead/dying battery was in place, the lights would power on dimly while the key was on, and I would hear a clicking sound while trying to start it, but it would not turn over. The battery was tested and needed to be replaced. Now, with a new battery that has been tested to be good, I don’t get any electrical power when turning the key.
What should I do if I Turn Key to ” start “?
Have someone turn key to start position, check voltage at battery, and see if there is a drop, voltage drop should be minimal, if not there is a direct short somewhere in the ignition circuit, which I doubt because it would blow a fuse, unlss you have an external relay for the starter system. If you get the kill I would suspect relay.
How much does it cost to get a new turn key?
You will have to pay for a new key or pray that you have a spare chip key. It can cost upwards of $500-700 dollars to have a new chip key programmed, plus waiting for the dealership to open, and to get towed there.
