What voltage should a stop-start car battery be?
The maximum voltage value set for AGM-batteries is in the range from 14.2 to 14.4 volts. This parameter must be installed on the charger before starting work. And for the current strength, it is recommended to choose the same value, not more than 1/10 of the capacity of the restored battery.
Does low battery affect start-stop?
Restricted start-stop functionality Due to the incorrect battery the amount of electrical energy is too low which will lead to rapid deterioration of the battery and causes the start-stop system to rarely or even never switch off the engine. This causes increased fuel consumption and greater pollution.
What does it mean when it says start-stop not ready battery charging?
The message is advisory, not a warning of something wrong. The batteries charge state is accessed and if there is not enough charge the ESS is turned off to allow the battery’s to charge up. Cause while you use the ESS it drains the battery’s while the engine is off.
How long does it take for stop/start battery to charge?
To boost your battery enough to be able to start the engine, it would take around 2-4 hours. The best way to maintain a long life for your car battery is by recharging it slowly. It is possible to recharge your battery more rapidly, but this may damage its long term performance.
Why does the start-stop system do not work?
The reason why the start-stop system does not function can be due to the interaction between both of these essential systems. The top priority for any battery is to start the engine. However, if the battery only has a low charge, the Battery Management System (BMS) switches off the start-stop function to enable the engine to be started.
How does auto start stop on-vehicle charging work?
They put a new Intelligent Battery Sensor on it (this is usually a sensor on the negative post of the main battery). Next they replaced the aux. battery (vehicles with ESS usually have two batteries, not one). Finally, they reprogrammed the PCM to make the Jeep “learn” how to use ESS again.
Why does battery management switch off the start-stop system?
The battery management switches off the start-stop function The top priority for any battery is to start the engine. However, if the battery only has a low charge, the Battery Management System (BMS) switches off the start-stop function to enable the engine to be started. A similar protective mechanism operates in the following cases:
Why does stop / start not available battery charger work?
I hate the Stop/Start feature but it’s well documented that when the secondary battery is really dead it causes all sorts of electrical issues. So if the battery was the problem keeping an eye out for this message would be a good warning that the secondary battery is about to go.

What causes a car battery to not start?
Most auto parts stores will test a battery for free to see if it has enough voltage and cold-cranking amps to start the engine. If the battery passes the test, then it isn’t being sufficiently recharged. That could be caused by corrosion on the battery terminals, or a loose or faulty cable.
Why is the start stop not activated on my car?
If the engine is not heated by consumers or by the battery, it must generate its own heat by combustion, which requires a higher starting current. The result: The start-stop function is not activated.
