Voltage of a Lexus
The voltage of a Lexus car battery can vary depending on whether the car is running or not. When the car is not running, a healthy, fully charged battery should read around 12.6 volts or higher. If the car has been sitting for a few days, the voltage may drop slightly but should never drop below 12.2 volts.
When the car is running, the voltage should be higher due to the alternator taking over in generating the power needed to run the electrical systems in the vehicle. At idle under minimal load, a Lexus’s voltage at the battery should hover at or above 14 volts, often closer to 14.5 volts. With the headlights, blower motor, and radio on, this voltage should change very little. If the voltage begins to drop into the low 13 volts or below, especially rapidly as the loads increase, a failing alternator is likely to blame.
In a specific case mentioned in a forum post, the volt meter showed 13.4 volts when the car was not running, and when the car was running, it showed 14.5 volts. Another user mentioned that the voltage at the battery was 12.9 with the car off, and once the car was started, the voltage stayed at 12.8/9 for about 5 to 8 seconds, then slowly went up to 13.4 or 13.5 volts.
In summary, a healthy Lexus car battery should read around 12.6 volts or higher when the car is not running, and the voltage at the battery should hover at or above 14 volts when the car is running under minimal load.
If you have any concerns about the voltage of your Lexus’s battery, it’s recommended to have a professional technician diagnose the issue to ensure the proper functioning of the charging system.

How many volts is a Lexus RX 350?
What kind of car battery does a LEXUS RX350 use? You will need a 12V lead acid car battery for your LEXUS RX350. Century, Panasonic and Varta make batteries for your LEXUS RX350 and we also have other brands. Some newer vehicles may have Idle Start-Stop.
At what voltage does a car start?
12 volts
Your car battery is essential in getting you where you need to go. Specifically, your battery often needs 12 volts of power to start your vehicle.
At what voltage is a 12V battery dead?
11.9 volts
A fully charged battery should register at 12.7 volts or more. If the voltage falls below this number, the battery should be recharged. A battery is only charged by one quarter at just 12 volts. Once it drops to 11.9 volts, your battery is considered dead.
What is a bad alternator voltage reading?
If the voltage does not change when the engine is started, or if it does not read between a minimum of 13 volts and a maximum of 15 volts, the alternator may be faulty.
At what voltage is a car battery dead?
11.80 volts
A car battery’s voltage may vary but only in a narrow range, from a fully charged 12.88 volts to a totally dead 11.80 volts. The difference between a fully charged car battery and a dead one is only 1.04 volts.
What kind of battery is used in a Lexus RX 350?
| Model Year | Model(s) | Battery Type |
|---|---|---|
| 2019 | GX 460 | CR1632 |
| ES 300h, ES 350, GS 300, GS 350, GS F, IS 300, IS 350, LC 500, LC 500h, LS 500, LS 500h, LX 570, NX 300, NX 300h, RC 300, RC 350, RC F, RX 350, RX 450h, RX 450hL, UX 200, UX 250h | CR2032 | |
| 2018 | GX 460 | CR1632 |
What is car normal voltage?
12.6 volts
When discussing car battery voltage, we’re generally talking about a 12-volt battery. When we take a closer look, we see car battery voltage can range anywhere from 12.6 to 14.4. With the engine off, the fully charged car battery voltage will measure 12.6 volts. This is known as “resting voltage.”
Does Lexus have a 12-volt battery?
To recap, Lexus hybrids generally contain two batteries: a 12-volt battery (which powers systems such as the headlamps and audio) and a high-voltage hybrid system battery (which supplies the power to start the combustion engine and drive the electric motors).
What are signs of a bad alternator?
How Do You Know if a Car Alternator is Bad?
- Trouble starting your car.
- Frequent stalling.
- Whining or screeching noise after the vehicle starts.
- Dim or overly bright lights.
- Smell of burning rubber or wires.
- Dead battery.
- Battery dashboard warning light is on.
What is normal alternator voltage?
The alternator output voltage is a crucial parameter. For the most cars, the regular voltage is considered to be from 13.8 up to 14.4V – regardless of the engine operation mode and the number of the consumers that are on.
