Idle stop start cars are very common in Australia and they need a battery that is suited for this specific system.
It is recommended that a battery replacement is only carried out by qualified professionals as most stop start vehicles have active energy management systems. The new battery needs to be configured correctly or there is a possibility that the car could begin charging the new battery using data based on the old battery's information. This can result in early failure of the new battery, loss of the stop start function, increased emissions and potential damage to the electrical system.
