In a car with Start-stop technology the battery must only be replaced with a type which has been approved by the car manufacturer and which meet all of the necessary requirements.
Does a stop-start car need a special battery?
Start-stop systems require a battery with modern technology, because normal starter batteries are not designed to meet the higher demands of these vehicles. The architecture of the electrical system in modern vehicles requires a compatible battery technology in order to function properly and reliably.
Does the Volvo XC60 have two batteries?
Cars with the start/stop function are equipped with two batteries – one more powerful 12 V starter battery for starting and one support battery that helps during the function’s starting sequence.
Does low battery affect start-stop?
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.
Can I replace stop-start battery? – Related Questions
What is the lifespan of a stop/start battery?
How long does a Stop Start battery last? Conventional lead acid batteries can last for up to 4-5 years if maintained properly.
What battery do I need for start-stop?
Start-stop batteries come in two different types: EFB and AGM. Enhanced Flooded Batteries (EFB) are suitable for small and mid-range cars with entry-level start-stop systems. They’re also known as Advanced Flooded Batteries (AFB) and Enhanced Cycling Mat (ECM) batteries.
Do I need to reprogram my car after battery replacement?
Under normal circumstances, you don’t need to do anything else other than keep driving the car after resetting the computer. The ECU will eventually relearn its ideal settings and reprogram itself with use.
Does a start/stop car need an AGM battery?
If your vehicle has a Start Stop System, you will require an AGM or EFB Battery.
Is it worth upgrading to an AGM battery?
AGM car batteries have unbeatable advantages over standard, flooded batteries: More starts per battery. Faster recharging. More durable construction.
Can you replace a AGM battery with a regular battery?
Only replace an AGM with another AGM
Replacing an AGM with an EFB or conventional battery would be like using the wrong spare part. The battery life is shortened, and the performance of the Start-Stop and comfort functions of the vehicle are not guaranteed. Therefore, replace AGM only with AGM!
How long does an AGM stop/start battery last?
We can generally say an AGM battery can last two to three times as long as a flooded battery. In the commuter car example we referenced, if a flooded battery lasts three to five years, an AGM battery could last six to ten years or longer.
What happens if you put a normal battery in a stop/start car?
A sudden escape of battery acid can cause a severe risk to health. Use of the incorrect battery technology in a start-stop vehicle results in more rapid deterioration of the battery. Because of this, as a result of overload, in extreme cases the battery acid may also leak.
What is the difference between a stop/start battery and a normal battery?
The most notable difference is the capacity of the battery. A Stop/Start battery must be able to provide enough power to start the engine, even when the engine has been turned off for a long period of time. This means that a Stop/Start battery must have a higher capacity than a regular car battery.
Why do some cars require AGM batteries?
AGM batteries are extremely resistant to vibration, are totally sealed, non-spillable and maintenance-free. AGM offers better cycling performance, minimal gassing and acid leakage when compared with conventional lead-acid batteries. The result of all the features of AGM technology is superior life performance.
How do I know if my battery is AGM or EFB?
In the case of AGM batteries, it’s usually mentioned on the label. However, if you don’t see AGM written anywhere on the label, you can look for the model number of the battery and check for its information online, or contact the manufacturer and ask for it.
What happens if you charge an AGM battery with normal charger?
AGM batteries require a slower, more stable charge than flooded batteries and can’t sustain the high charging speeds used by standard battery chargers. If you charge an AGM battery with the wrong type of charger, you will end up under or overcharging your battery.
