The combination of the latest technology and superior German quality Varta Silver Dynamic batteries ensure uninterrupted operation of the car in any, even unforeseen situation. Production is carried out at European enterprises, primarily in Germany, the Czech Republic, Austria, France and Spain. The product has won the markets of many countries of the world due to its reliability and durability. Car owners are confident in the excellent operation of the battery of a well-known German brand.

Where does Varta Silver Dynamic D21 apply

The trust of consumers around the world to the battery is based on its merits. The product is practically resistant to corrosion and provides significant starting power corresponding to the energy requirements of modern cars. Silver Dynamic is applied in cars in which the Start-Stop system is not provided.

The design and manufacture of a car battery is focused on vehicles with strong engines and high power consumption. The products of German experts guarantee a quiet, uninterrupted operation of powerful cars. A high class of products ensures a reliable start-up of a car equipped with a variety of energy-intensive equipment.

The unique technologies that are used in the manufacture of this battery are actually the invention of the future. Thanks to this, owners of powerful foreign cars can enjoy the smooth operation of their cars. Optimum conditions for the passage of energy, maximum performance, reliable operation distinguish this product.

Specifications

The technical parameters of batteries of a well-known German brand create confidence among their owners in:

1. security;
2. facilities;
3. longevity;
4. reliability.

The model with ETN code 561 400 060 is characterized by the use of uniform coating technology with electrode elements on both sides. A separator with a larger capacity is being installed. Due to this, the efficiency and duration of the operation of the product significantly increases.

The electrode grid of this car battery has a unique design and makes it possible to create a maximum voltage on the starter, regardless of the temperature of the air and time of year. Testing of Varta car batteries is carried out in accordance with German DIN standards.

It is worth noting that this model is low base, due to its small height and overall dimensions: 175x242x175 at 14.87 kg. It is well suited for diesel engines, as they need increased power, especially in the cold season.

Silver Dynamic D21 is characterized by excellent performance at maximum cold start. Durable and reliable in harsh environments.

How is the battery maintained?

The use of new technology based on silver-containing alloys of the electrode lattice increases the life of the varta product by 20%. Topping up water for the entire period of use is not required. Safety is provided by a cover design. There is no need to remove the cover from the battery case.

There is no evaporation in a maintenance free battery. The tightness of the product, the presence of a special labyrinth for condensation of steam, maintains a constant amount of electrolyte. Do not try to open the cover - this is not provided for in the design.

How to charge the battery

Discharging is a process that is natural for a maintenance-free battery, as for most mechanisms. This product can be charged under conditions of partial or complete discharge once every 6 months. Battery maintenance consists of proper charging. For these purposes, you need a charger and detailed instructions.

1. First of all, it is necessary to measure voltage with a voltmeter or determine the state of charge based on the color of the indicator located in the upper part of the case.
2. When fully charged, the indicator is green. Its darkening - down to black indicates the need to charge the product.
3. A light yellow indicator indicates a significant decrease in electrolyte level. Do not add water to a maintenance-free battery. It is also forbidden to light from another device in this condition.
4. All devices powered by energy are turned off. The voltage at the battery terminals is measured with a voltmeter. At voltage indices less than 12.2 V - full discharge, in the range from 12.2 V to 12.4 V - partial.
5. The product is charged using direct current, the indicators of which are equal to 1/10 of the battery capacity. After 2 hours, they switch to charging with a current of 1.5A or stop completely. This is the safest way.
6. It is not allowed to carry out fast charging, which provokes overheating and destruction of the plates. In order not to boil the electrolyte, it is necessary to periodically turn off the charger, and cool the liquid.
7. If the battery is completely discharged, contact a specialist center. This process is longer and requires constant monitoring by a specialist.
8. A maintenance-free battery is charged at room temperature in a warm, dry room.
9. All devices and ignition are put into sleep mode. The hood remains open to prevent short circuits. The charger is connected to the battery at low current readings. It is included in the network. In this case, the current strength increases gradually in order to avoid voltage surges.

I already have a second Varta. The previous one departed for 5 years. No problems arose. Often the car slept in the cold on the street, but in the morning it started up fine, quickly grabbed. Very satisfied.
