Where is the battery temperature sensor located?
On most domestic vehicles, the battery temperature sensor is located underneath the battery box and is placed directly below the battery. Most batteries develop excessive heat towards the bottom of the core and often in the middle of the battery, which is why the temperature sensor is located in this position.
What is a battery temperature sensor?
The BTS mounts on a terminal post of a battery in a bank or on the side of a battery and measures its temperature. It sends precise information to the charger or charge controller, which automatically adjusts voltage to help ensure full battery charge depending on the ambient temperature of your battery installation.
How do you test a battery current sensor?
Start the vehicle and add electrical loads. Turn DVOM to duty cycle. Ground the black lead, then take the red lead and back probe the current sensor signal terminal of the battery current sensor. If no duty cycle signal is present, replace battery current sensor.
How do you install a battery temperature sensor?
To install a BTS: Switch off all devices operating from the battery. 2. Connect the ring terminal on the sensor directly to the negative battery stud, or use the adhesive backing on the sensor back to attach the sensor to any side of the battery to be monitored.
What is the battery temperature?
Battery temperatures are going to vary of course but I have found that the battery in an Android cell phone often remains in the 30 °C range sometimes in the low 40s depending on the phones usage (86 °F – 104 °F)…
What happens when a battery temperature sensor goes bad?
If the battery temperature sensor fails, it can also cause the Battery Light to become illuminated. If the system is affected in any way that causes the battery to not be charged, and it is picked up by the computer, it will illuminate the Battery Light.
What happens when a battery current sensor goes bad?
If the computer is receiving an incorrect signal from the battery temperature sensor, it can stop a proper charging and cause low voltage. The vehicle with a low voltage is hard to start, and may also cause other problems for the vehicle’s electrical system.
Can you bypass a battery current sensor?
If a car has a battery current sensor and additional electrical accessories are connected directly to the battery negative terminal, it may cause problems, because the electric current will bypass the battery current sensor and its readings won’t be accurate. Replacing the battery sensor is not very expensive.
Do I need a battery temperature sensor?
Need for Temperature Sensor in a Battery Charger This prevents overheating of the battery. At lower temperatures, the battery charger applies higher voltage to the battery to counter the increased resistance due to low temperature.
How do battery temperature sensors work?
As its name suggests, battery temperature sensors detect the temperature of the battery so that the charging system voltage can be increased or decreased according to the vehicle’s needs. When the battery temperature is low, the system voltage is set high and will automatically decrease as the temperature increases.
What temperature is bad for a battery?
The standard rating for batteries is at room temperature 25 degrees C (about 77 F). At approximately -22 degrees F (-30 C), battery Ah capacity drops to 50%. At freezing, capacity is reduced by 20%. Capacity is increased at higher temperatures – at 122 degrees F, battery capacity would be about 12% higher.
Where is the battery temp sensor on a Cummins diesel?
Battery temperature sensor is snapped into battery tray below driver’s side battery. 1.Battery temperature sensor is snapped into battery tray, below driver’s side battery. Disconnect wiring harness at battery temperature sensor. 2.Using ohmmeter, check resistance between electrical terminals on battery temperature sensor.
Where is the temperature sensor on a car battery?
The sensor is located on a battery terminal or the case. The battery sensor’s function is simple: if it senses a temperature variation, it orders the battery control module, or the computer control system in a car or truck, to change the charging rate.
When to replace the battery temp sensor in a jeep?
Resistance should be 9000-11,000 ohms at 75-80°F (25-27°C). Replace battery temperature sensor if resistance is not within specification. 3.If problem exists in battery temperature sensor or wiring circuit, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See SELF-DIAGNOSTICS – JEEP, TRUCKS & RWD VANS article.
Why does the battery temp sensor stop charging?
I don’t believe that the battery temp sensor can stop charging completely it will cause the PCM to lower the charging voltage. Battery temperature sensor delivers input signal to Powertrain Control Module (PCM) to indicate the battery temperature. PCM uses battery temperature input to modify rate of output from the charging system.
Where can I get a battery temperature sensor for a Dodge?

Where was the old battery temperature sensor located?
My old sensor had its wires chewed up by wear and tear in the engine bay, this one not only replaced it perfectly but its wires are enclosed in a wrap that should protect them much better than the previous sensor.
Why is my battery temperature sensor not working?
Checking out why Alternator charging excessively and burning my batteries out. No code came up to throw check engine light on. While searching internet came up that Battery temperature sensor helps control alternator charging in charging too much on hot days and not enough on cold days.
