Quality Policy Statement …

Customer Experience Policy

GEP considers being a customer-oriented company and providing its customers with a unique and perfect customer experience as its primary objective.

In order to realize this objective;

It is aimed to meet and exceed the expectations of customers. In order to exceed expectations, insight is obtained through ethnographic research, contextual interviews, surveys, and the customer’s voice is taken into account.

Customers are taken to the center in all processes and all employees know that the reason for their existence is customers. Corporate culture and strategies are established accordingly.

The same language is spoken with the customer and it is ensured that employees always think in the same way customers do.

Customer Journey Map is designed to determine the points of contact and the emotions at these points of contact and continuous development of points are ensured.

Elimination of problematic points that do not add value to the customer and providing a smooth experience in all end-to-end processes at the contact points are among our priorities.

To listen to our customers, we establish feedback mechanisms that are accessible to our customers. Our customers can easily access the Experience Center through different channels even after-sales. Customer suggestions and complaints are recorded in the CRM system and every customer is returned as soon as possible.

GEP  undertakes to evaluate all applications in a fair, equal, and impartial manner.

We carefully regularly review and continuously improve all processes and used systems in contact with the customer to identify areas that are open to improvement and increase efficiency.

What is the Battery? How Does It Work?

The battery is equipment that stores electrical power in the form of chemical energy and gives it back in case of need. The task of the battery gives electric current to the starter motor for the first time to work, to send current to the receivers when the vehicle engine is not working. The other task of the battery provides a balance between voltage and amperage in the electric system when the engine operates and thus to prevent the receivers from damage as a result of high voltage that the alternator may generate at high speeds. In such cases, the battery takes over some of the current generated by the alternator and prevents overvoltage.

How to Jump Start a Battery?
  • Make sure that the battery you use for connection of one battery to another is of the same amperage.
  • Switch off the engine and all electrical components.
  • First, the red cable end is connected to the (+) terminal of the discharged battery; then the other end is connected to the terminal of the charged battery.
  • And then the black cable end is connected to the terminal (-) of the charged battery and the other end of the cable is connected to any metal part of the vehicle having the discharged battery.
  • Make sure the cables do not contact with any moving or hot things such as exhaust and impeller.
  • And start the vehicle with the charged battery first, and then start the vehicle with the discharged battery.
  • After the cars start, you may remove the jumper cables, starting with the vehicle with the discharged battery.
Why Does Battery Discharge?

Possible reasons for discharge for GEP Batteries you bought:

  • Adverse environmental and storage conditions, high temperature, humidity, etc.
  • Leak currents on the car (currents drawn more than the anticipated short circuits), open lights
  • Short circuits on other electric equipment and components
  • Mismatch of the vehicle and battery; selection of small battery; additional onboard vehicle components (audio, light, computer systems, cooling systems)
  • The insufficient charge generated by the alternator (charging generator)
Are Batteries Harmful to the Environment?

Batteries have consisted of lead, sulfuric acid solution, and polypropylene box. For this reason, when batteries become unusable, they are risky and hazardous waste for the environment. However, an effective recycling system makes it possible to recover the polypropylene box and lead components of the batteries. Although it is also possible to recover sulfuric acid, it is mostly preferred to neutralize it.

How to Install Battery?

Selection and Installation of Battery

Select the battery you desire properly according to the vehicle from the lists given in our catalog indicating characteristics of the batteries. Sizes, cold cranking current, and capacity values are important selection criteria. Activate the dry charged batteries according to the method given above and, if required, charge them.

In the case of flooded batteries stored, when the average daily temperature is less than 4°C, if the open-circuit voltage is 12.50 V and less, then recharge it according to the method given above.

If the ambient temperature is high and the open-circuit voltage is 12.40 or less, recharge it according to the method given above.

Mark the cables as +/- before you remove the old battery in order to connect the new battery correctly.

Measure the voltage value and direction of the battery to make sure it is correct; check the cable connections and battery stand carefully and clean them. Place the new battery and make the connections and tighten.

Firstly, connect the positive (+) cable. Secondly, connect the negative (-) earthed cable. Tighten carefully. As overtightening may damage the posts, be careful especially when you tighten the battery posts from sideways.

Cover the posts and cable ends by an anti-corrosive agent.
