No, it''s not necessarily your battery. Many engine parts connect to the battery and the source of the problem can be there. Reasons why voltage peaks Loose connections. A simple problem of loose wires and connections can cause your
When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9-15.5 V, depending on the battery state of charge and estimated battery temperature.
I had macOS 15.1.1 installed on my M3Pro and it drained the battery completely even while my MacBook was plugged into the 90W USB-C charger. At some point my MacBook went off at 20% (without beeing charged) my MacBook has 38 charging cycles and the battery capacity is still at 100% .
15.1 volt is a little high, but some cars are running at that voltage. The battery will actually need a higher voltage to fully charge it, but this area is not normally used. So what voltage is the alternator designed to work at ? If not 15.1 volt, return as faulty. If it is 15.1 volt,
I noticed during a couple of recent trips in my 2017 LT that the voltage that is displayed on the DIC can be as high as 15.3 at times. Yesterday I drove 50 miles and it was at 15.3 the whole time.
“We charged up our Lithium battery to 14.2V, and the percentage of charge read 100%. Then we used our appliances for a couple of hours, ran the lights, watched a
Voltage at idle should typically be between 12.5 and 13.5 volts. At idle, the alternator should be putting out enough voltage to maintain battery charge and power the vehicle''s electrical systems. As you start your car, the
The smallest possible set value for the generator voltage is 12.2 volts, while the maximum charging voltage can be anywhere between 14.5 and 14.9 volts. However, when the
My 2015 Acadia with 40,000 km.has a battery voltage of 12.6 when started, with the voltage rising to 15 to 15.5 after a few minutes. In summer, this voltage stays in the 15V region as I drive for perhaps up to an hour or
When I would let off the throttle while in gear, the voltage would jump up as high as 14.2 volts, then back down when back on the throttle. When I was stopped at idle, voltage would drop to as low as 12.1 volts. This does not seem normal to me. Typically, the voltage should be around 14 volts during normal operation, so that the battery will
Automotive voltage regulators always maintain output voltage at some value above the 13.2 - 13.4 volts required to run the car as well as maintain full charge. A fully

Did I do anything bad to the new battery? The new battery voltage reading was 12.68V after I corrected my mistake on the multimeter. I also found P0706 stored when I did a scan. I don''t experience any transmission shifting problems. The transmission fluid was drained and filled 20,000KM ago. Should I clear the code to make sure it will come
It is due to the alternator in charge of charging the battery creating a higher voltage than the battery''s normal voltage. Why is my car battery showing 15 volts The best answer is, a rectifier transforms the alternating current (AC)
This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator. With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator
A car battery''s voltage should be around 12.6 volts when fully charged. While the voltage can vary slightly depending on the type of battery and the specific conditions, a voltage of 15
My dads 2016 LML has been turning over a little on the slow side for a while, but this morning it wouldn''t turn over at all. I jumped it with another vehicle and checked the battery voltage with it running after the jump vehicle was disconnected. It was reading in
If output voltage is above 15.1 volts with the ambient temperature above freezing, the battery''s electrolyte level is frequently low, or you smell "rotten eggs" around the battery, then you are probably overcharging the battery and the charging system should be tested.
Good alternators measure the voltage at the battery terminals and use whatever voltage at the alternator that is required to obtain good voltage at the battery terminals. So, as a summary, you should be measuring the voltage at the battery terminals. There the voltage should be between 14.1 VDC and 14.5 VDC.
The voltage was 14,9-15,1, when I register it (it was only one icon for manage that), the voltage goes to 14,8-14,9. But right now the battery isnt fully charged, so maybe it can increase the voltage also. Just make sure to register the battery and you should be good. Voltage shouldn''t be exceeding 14.7 - normally when all things are
Battery voltage may be fine, but I bet the cranking amps are not even close. Replace the battery and the alternator will settle down to the 14.7 Charging volts. 19 people found this helpful. Mark helpful. 100 Report; biull3022 answered 9 years ago I had the battery replaced by AAA yesterday.
First question, what is the actually battery voltage. I recommend testing it with a multimeter. Since a recently charged battery can read a false high, after turning the car off keep the low beams on for about 30 seconds.
Battery voltage is good after sitting for a few days (12.7 vdc) (hood left open the day before checking w/ multimeter) No "low battery" warnings.. Start vehicle and DIC says battery voltage is 13.8..... good/alternator working properly... Drive car on highway for 30min. and battery voltage up to 15.3..
After looking into this question and checking with my resources I have found that the displayed battery voltage will fluctuate at all times. The normal expected battery voltage should be between 10-15 volts. If you feel
Jump started and drove 15miles home. I checked battery voltage when I got home an hour later and battery was 12.4 v . assumed something was left on and drained the battery. I decided to use the car myself the next morning, put the gauge panel in test mode and monitored voltage while driving. 14.7 to 15.3 volts .I confirmed this voltage at the

Sense wire thought battery was being charged at 14.5ish when in reality it was at least a full volt higher. I traced the voltage drop all the way back to the engine fuse box.
IIRC the alt charges the pass side battery yet the signal to regulate the alternator is off the drv side battery, so if the ecm/alt sees low voltage its going to go max output(14.8) trying to top up the pass side battery, usually end result is a boiled over or exploding pass side battery also battery temp sender is located on driver side battery
Voltage is way too high. 14.8 volts at the battery when cold. When hot, 14.2 One wire alternators don''t regulate voltage well, this is a known weakness. Three wire use a voltage sense line to the battery which carries no current so the voltage is the same at either end.
Usually, a good battery has a voltage or power level of between 12.6 to 12.8 volts.When the voltage exceeds the range, it could be a sign of something wrong with the charging system or
Hi I have a 2014 Cruze LT with 1.4 turbo engine. My battery I''ve noticed on dash has been up in the 15.1-15.4 range and I changed alternator and put in brand new battery. Is
The charger puts out about 14.8V to charge a 12V battery during the day at peak (around 1pm). At night time, the battery is at about 12.8-13.1V fully charged. I disconnected the solar panel last week and the voltage has been steadily
The most accurate method is to open your hood and let the car go to sleep again, as I have found that if I open a door to the car causing it to come awake and the fuel
If your car''s battery''s voltage consistently shows 15 volts or higher, it could be a sign that the battery is being overcharged. This could happen if the rectifier has to be repaired or if the alternator isn''t working properly.

If the battery is showing a voltage of 15 volts, it could be an indication that there is a problem with the charging system in the vehicle. Potential causes of high battery voltage include a faulty alternator, a wiring issue, a failed voltage regulator, or other issues.
However, when the battery is in a refresh phase, the voltage may occasionally reach up to 15.2 volts. Ok, so it sounds like it is an acceptable voltage. I guess my only concern is that Ive never tested it below 15 volts and it's a brand new battery. I'll see how it goes over the next few days.
In conclusion, it is normal for a car's battery to show a voltage of around 12.6 to 12.8 volts when it is not being used. If the battery is showing a voltage of 15 volts, it could be an indication that there is a problem with the charging system in the vehicle.
A voltage of 15 volts is relatively high and could indicate a problem with the battery or the charging system. The alternator or voltage regulator is not functioning correctly and overcharges the battery. The battery and other elements of the charging mechanism may sustain damage as a result.
It is generally not normal for the alternator in a vehicle to produce a voltage of 15 volts. The typical range for the output voltage of an alternator is between 13.5 and 14.5 volts. If the alternator is producing a voltage of 15 volts or higher, it could cause damage to the battery and other electrical components in the vehicle.
I think that 15 volts is on the high side even if it is within specs. The smart regenerative charge system primary strategy is stored in the BCM . The BCM receives all of the important information relating to the battery condition from the battery monitoring sensor via the LIN .
