Frequently Asked Questions
I use a Start&Stop Battery in my car. I've purchased the battery recently but Start&Stop does not run. What should I do?
In order to activate the system in vehicles furnished with Start & Stop feature, the battery should have sufficient voltage value. If the battery voltage is low, the system will not activate but the battery will start. In this case either the battery should be charged or it is ensured that it is charged by driving the vehicle for a while. It should be noted that the voltage value is minimum 12,60 V while placing Start & Stop batteries to the vehicle.
My battery is empty but warranty continues. What should I do?
In case of any problem during the warranty period, the battery should be checked by the dealer from which it was purchased. If it is detected as the result of the examination that there is a production related fault in the battery, it is replaced with a new one under warranty. If it is detected that the error is caused by the user (such as discharging, sulphatisation due to long waiting period, crack etc.) then the battery will not be under warranty coverage.
The warranty of the battery continues but the invoice and warranty certificate are missing, what should I do?
If you lose your battery's warranty certificate, please consult to the dealer from which you purchased your battery. In these circumstances, warranty replacements can be done by obtaining approval from the dealer from which you purchased your battery after the controls are performed.
What are the differences between 60 Ah and 72 Ah batteries?
The capacity value stated on the battery labels indicates the amount of energy that can be withdrawn from batteries. A battery with the capacity of 72 Ah provides 20% more energy than a 60 Ah battery.
What points should I consider while charging the battery?
The method that should be followed while charging the batteries is to charge it with 1/20 of the battery capacity (for example 60/20=3A for 60 Ah) for 24 hours. Voltage limit of 15,6 V should be applied for standard flooded batteries and 14,4 V should be applied for AGM and gel type batteries. You can consult our service support unit for battery charging operation.
Are battery terminals made of lead alloy or silver alloy?
Battery terminals are made of lead alloy and do not contain any silver. Silver-lead alloys are used in grid alloys of some batteries but no battery has silver terminals.
There is a swelling in the battery I am using in my car, what is the reason?
Excessive charging may cause swollen batteries. Excessive charging must be avoided as it will damage internal structure of the battery. Furthermore, there may be swelling in batteries with vent plugs if holes or air outlets on the plugs are occluded. We recommend you to visit our nearest authorized dealer and have the charging system of your vehicle checked.
They told me that electrolyte level in battery had decreased and instructed to refill with pure water. Is this information correct?
Electrolyte level in the battery may decrease in time depending on the usage. In these cases (in batteries with vent plugs), the electrolyte level must be refilled until the maximum level by adding pure water in every cell. No fluid other than pure water should be used. You can have your battery refilling operation done by visiting our nearest service support unit.
Which of your battery line can be used in Solar Systems?
Gel type batteries with long service life are the most suitable batteries for use in Solar systems. Alternatively, our 100Ah and 150Ah VRLA batteries can also be used in these systems. If our Full Energy batteries are used, battery charging voltage level of the system must be minimum 15.5 V. However we recommend you to consult to experts on the selection of the battery according to the project characteristics.
Does the battery with low voltage/charge affect fuel consumption?
In standard vehicles, the battery has no effect on the fuel consumption. However, if batteries with insufficient capacity or low charge level are used in vehicles with Start & Stop feature, this will increase the fuel consumption since Start & Stop will not activate.
What points should we consider while charging the batteries in terms of our work safety?
Reaching to high charging voltage levels while charging the batteries causes gas formation. These gases are hydrogen and oxygen formed as the result the electrolysis of water. Since hydrogen gas is explosive, its accumulation in large quantities in indoor areas is dangerous. Therefore, battery charging areas must have a good ventilation.
What is the difference between EFB and AGM battery?
Both EFB and AGM batteries are developed for use in vehicles with Start&Stop feature. EFB (Enhanced Flooded Battery) type batteries are flooded type batteries which have outstanding performance. They can be used in replacement of standard flooded batteries, too. AGM (Absorbed Glass mat ) are referred to dry batteries and they are special batteries wherein the electrolyte inside is absorbed by separators. These batteries representing the highest level in battery technology have a very high performance and longer service life compared to standard batteries. AGM batteries cannot be used in replacement of standard flooded batteries as they are heat sensitive. AGM batteries are suitable for use in vehicles using AGM type batteries.
What points should be considered while installing the battery?
While installing the battery, positive terminal should be connected first and negative one should be connected later. Terminal connections must be made tightly.
What is the benefit of cleaning the battery surface frequently in large vehicles (trucks and pick-ups) not having an enclosed box for the batteries?
Dirty outer surface in batteries increases self discharge of batteries. Cleaning the dirt eliminates this risk and extends service life of the batteries. It is recommended to clean battery surfaces regularly.
What does 12 V 60 Ah 540 A on the label mean? What do values such as DIN, EN, JIS, SAE in cold cranking current indicate?
The value 12V stated on the label shows electrical voltage of the battery in volts. The value 60 Ah indicates the battery capacity, i.e. the total amount of the energy that can be withdrawn from the battery. The value 540A indicates the cold cranking current to be provided by the battery under -18˚C according to EN standard. DIN, JIS and SAE values indicate other standards. EN indicates European standard, SAE indicates the American standard, DIN indicates former German norm and JIS indicates the Japanese standard.
How is the warranty coverage evaluated in commercial taxis that do not have a battery suitable for the vehicle type used? (Vehicles not featuring 65 Ah and 72 Ah batteries)
In commercial taxis, the battery will not be under warranty coverage if taxi battery is not used.
What is the difference between sealed cover system and removable plug system?
In batteries with sealed cover system, batteries are more resistant to leakage thanks to the labyrinth structure under the cover. Any mistreatment by the user is not possible either since there are no removable plugs. There is no need to add water since our batteries with selaed cover system are maintenance free. Therefore, fully sealed cover, which is safer, has been adopted.
What is the meaning of SFB?
SFB is the abbreviation for Superior Flooded Battery.
Is there any water loss in sealed batteries in hot weather, is it more appropriate to purchase a battery with removable plugs?
No fluid refilling is necessary since all of our batteries are maintenance-free type. Therefore, there is no need to use a battery with removable plugs.
Is there any problem if the engine is running while installing the Start&Stop battery?
Another duty of batteries other than starting the vehicle is to ensure stabilization of the electrical system. If the battery is removed while the engine is running, irregular current from the alternator and high voltage may cause damage in the electrical system of the vehicle. Use of this method is not recommended under any circumstances since it may cause serious damage in the vehicle.
