Warranty

Before buying any spare part for the vehicle, it is recommended to review the options available in the market. Therefore, establishing a car battery comparison is one of the best ways to get a suitable model. In this, it is important that different parameters are established and one of the most important is the guarantee that the manufacturer grants the user with the purchase of the battery.

Most car battery models have a 12-15 month warranty. However, there are some of a higher range that offer up to 24 months. The more popular and inexpensive alternatives generally have a life of two to four years, so a 15-month warranty is long enough to test the quality of the equipment.

It is recommended to select models that have a long warranty period, to prevent any irregularity or damage that may arise.

 

Technology

There are different models and types of batteries that work with different technologies. In general, according to the technology they incorporate, the price of a car battery varies. So if you want to know how much one costs, you need to be able to know the technological specifications and the type of batteries you have in consideration. For example, there are alternatives that are new, others are older and are used by older car models.

New batteries tend to have a perfectly sealed, single-block design so liquid inside won’t spill, plus they have corrosion protection. These higher technology models do not require maintenance during their lifetime, supplying the electrical demands of the car. In contrast, older battery models require periodic maintenance.

 

Type

The batteries come in different types, so that lead acid (Pb-acid), nickel cadmium (NiCd), Ion-Lithium (Li-ion), air-zinc, polymer-lithium (Li-ion) batteries are available on the market. -poly), nickel metal hydride and fuel cells. Of these types, the most popular car models are lead acid because they are rechargeable and have a good price-performance ratio. In addition, they are the ones used by the vast majority of cars and have a continuity in the power supply.

 

Size

You can always find a good and inexpensive battery. However, not all the alternatives available on the market are suitable for the car model. It will be useless to buy a very cheap battery if in the end it will not work for the vehicle. On the contrary, it could represent a much higher expense.

For this reason, it is recommended to take into account the dimensions of the battery depending on the space of the car enabled for it in relation to height, width and length. Although there are battery-powered car models of different sizes, there is also a strong possibility that if the dimensions don’t match, it won’t work. To find out the technical specifications of the battery used in the car, it is best to consult the user manual or ask a mechanic for technical service.

Amperage and starting

Batteries have different amperages. That one model has more amps than another does not usually affect its performance or quality, but is more or less convenient depending on the electrical demands of different types of cars.

When it comes to volts, they represent electrical voltage. It is recommended that the models that are acquired as new have an electrical voltage higher than 12 volts, which represents a percentage of 60% of the load. In the case of starting, it is recommended that the models have a power greater than 300 A. Most battery models have between 300 and 540 A. Below this figure, the car will not start if the ambient temperature is less than minus five degrees centigrade.

 

 

 

Frequently asked questions

 

Q1: How can I check the car battery with multimeter?

After a period of use, the battery may begin to fail and this may be due to low liquid. One way to check is by using a multimeter to help test the battery status. To achieve this, the hood of the car must be opened and the battery cables disconnected. The multimeter must be set to 50 volts for the reading to be reliable. Then the red wire should be connected to the positive terminal on the battery, while the black wire should go to the negative terminal. After 15 seconds the meter can be read. If the value is less than 9.6 volts, you need to get a new battery unit.

 

Q2: Which car battery is better, Tudor or Varta?

Both brands have the endorsement of the user community and years of experience in the automotive sector, so that either of them offers high levels of quality. However, it will be up to the user to select one , based on the fact that Tudor usually incorporates batteries with AGM technology that is suitable for cars with stop / start and a regenerative power mechanism that make it a long-lasting alternative. On the other hand, Varta usually has an average life of five years, having a starting reserve of 600 amps, high capacity and suitable for cold climates.

 

Q3: How to charge the car battery?

In many cases, car batteries do not break down, they only discharge, so it is necessary to apply a charge to continue their operation. To start the car, it is necessary to make use of auxiliary cable clamps and another charged battery placed in a running car, placing the clamps to connect both batteries. Once the car has been started, it should be left in operation for about 45 minutes for the recharge to be effective.

 

Q4: When to change the car battery?

Batteries are the main generating component of the electrical energy necessary to operate the vehicle system, starting with the most important thing, which is to start the car. Sometimes you don’t need to replace them, just charge them. In other models, it is convenient to carry out periodic maintenance or clean the terminals. Now when the battery reached the end of its useful life, it should be replaced. If it charges and no longer acquires power or if a multimeter is used and it does not reach the required voltage, then it is time to replace with a new one.

 

Q5: How to disconnect the car battery?

To disconnect a battery, the car must be switched off and in a state of rest. Once the motor and the battery are at rest, the battery must be removed, disconnecting the cables from the terminals. It is indistinct which of the two disconnects first.

 

Q6: Why does my car battery drain?

There are several reasons that can lead to a low car battery . In some cases, it may be a vehicle electrical problem or that the alternator is not working efficiently. Another reason may be that the lights are being left on after turning off the car. Finally, it may be that the battery is defective and damaged. In any case, if this occurs repeatedly and the battery has had to be charged several times , it is necessary to go to a mechanical maintenance center to dispel doubts and solve problems.

 

Q7: How to change the car battery without losing memory?

To prevent this from happening, some techniques can be applied. One of the ways to avoid losing memory is by purchasing a 9-volt memory recorder from a spare parts store, which is capable of supplying the necessary power to the electrical devices of the car, during the short time it will take to change the power. main battery. Before removing the battery, all electrical devices in the car such as lights, radio and others should be turned off. Disconnect the negative cable and then the positive cable.
