Tip 1: How to choose a battery for a car

Since the battery can be called the heartcar, it needs to be changed in a timely manner, however, the question becomes how to choose the battery for the car, which will ensure its normal operation under any temperature conditions.

In the current market, batteries fromfollowing groups: 1. Repairability2. Unattended3. Low maintenance For those who want to choose a battery for a car for many years, the best option could be called maintainable, but this type of batteries is gradually disappearing from the market. However, modern motorists are increasingly marking its shortcomings, among which can be identified such as: low-strength body, high cost with low practicality, poor properties and strength characteristics of the covering mastic. Not the best option for those who want to choose a battery for the car, which will be convenient in operation, is maintenance-free. It is generally not subject to any repairs, which is why it is quite an expensive option, requiring high costs, in addition, these batteries are designed for special operating conditions and cars and are considered the most perfect. Thus, we can conclude that the most popular, convenient and affordable are low-maintenance batteries. They are presented in the broadest price range (from $ 100 and above), in addition, they allow a small introduction inside the device. For many, the main principle of choosing a battery is its brand and the brand name of the manufacturer. This is a very important aspect, however, not the only one to pay attention to. For example, you need to remember about the reputation of the store, you only need to buy batteries in a reputable store with a good reputation. Expensive and cheap models have many differences, preference should be given though not the most expensive, but with the most modern battery models that are convenient to use, reliable , and also have the optimal capacity.

Tip 2: How to choose the right car battery

A rechargeable battery is needed to start the engine and provide power to the electric appliances of the car. When observing the operating rules, the power supply must be replaced every 3-7 years.

You will need

- Instruction manual for the car.

Instructions

First of all, check theoperation to your vehicle. It contains the manufacturer's information on what kind of rechargeable battery you need. If you do not have this manual, inspect the battery you are using now. You will need to pick up a similar power source in terms of capacity, size, polarity and method of attachment in the car.

The most important characteristic of a batteryBattery - capacity, which is measured in Ampere-hours. If it is too small, there will not be enough energy to start the engine. When selecting a new power source, be guided by the capacity recommended by the car manufacturer, or by the engine displacement and engine size. The larger the vehicle's engine volume, especially if there is additional electrical equipment, the greater the capacity of the battery.

Observe the operating conditions of the device. If the machine is used in off-road conditions, under the influence of a strong shaking the active mass of the plates of the battery quickly dies. This may result in a short circuit. Therefore, it is worth choosing a battery model, in which the plates are placed in a special microporous envelope-separator.

Read the accompanying documentation. The quality of the goods must be confirmed by the appropriate certificate. Pay attention to the operating features, terms and conditions of service specified in the warranty card. If the warranty period is more than a year - then the manufacturer is confident in the quality of its products.

Before buying, carefully inspect the casebattery. Make sure that it is not damaged. Ask to measure the density of the battery electrolyte. Its value should not differ from the declared by the manufacturer more than 0.02 g / m³. Check the current accumulator with a battery probe. Its readings with the load switched off should be from 12.5 to 12.9 V, and when turned on - hold for 10 seconds. at a level of not less than 11 V.

Tip 3: How to choose a car charger

If starting the engine is difficult for anyreasons, it is quite possible that the battery will sit down and charge it only with the help of a charger or from another car. And that the process of charging the battery charger was as simple and effective as possible, buy a good start-up charger.

Instructions

When purchasing a charger, selectcharge circuit. It can be either with a fixed charging current, or with a fixed charge voltage. The first scheme allows you to charge the battery completely, but in the final part of the process, the rising temperature of the electrolyte can shorten the battery life. When charging a battery with a current with a constant voltage, this does not happen, but it does not charge 100%. Conclusion: purchase a device with a combined charging circuit (automatic), combining the advantages of both schemes and eliminating their drawbacks.

Automatic charger withthe combined charge circuit has only one control - a potentiometer, which sets the initial charge current. In addition, it has an ammeter or a complex of LEDs showing the strength of the charging current.

Select the device by charging method, whichcan be transformer or pulse. The first type of devices operate without frequency conversion and have a large and heavy transformer and a rectifier. Pulse also have a high-frequency transformer, but with a more modest overall size and a lower weight.

Depending on the terms of use, selectdevice operating from a 220 V electric network or from a car cigarette lighter 12V. Instruments operating from 220 V are extremely simple to handle, they are convenient and they can be put in the garage for the estimated time of recharging the battery. Devices designed for 12V, have a higher charging speed, which can be adjusted depending on the capacity of the battery. However, they should not be left on for a long time because of a possible recharge of the battery.

Choose between charger and start-up chargerdevice. Starting-charging models are more powerful, have an additional function of starting the engine, thicker lead wires and a more expensive cost. Simple chargers can only charge or recharge the battery, but they can do this without disconnecting the battery from the vehicle's on-board network.

Pay attention to the size of the charger(starting) current and select the device with a margin for this indicator. This way you will not only extend the life of the device, which will not work at the power limit, but you will also be able to charge more capacious batteries (for the future). The value of the charging current is directly proportional to the charging speed of the battery.

Tip 4: How to choose a vacuum cleaner for a car

Many car owners are monitoring the purity of theirauto. At the same time, it's not a problem to use car wash services, but it will not be a cheap pleasure, so sometimes it is more rational to clean up your car with your own efforts. A good properly selected car vacuum cleaner will be an assistant when cleaning the car.

When choosing a car vacuum cleaner, you need to clearly understand what parameters it should meet.

There are two types of vacuum cleaners:

Rechargeable, this type of vacuum cleaner does not worklonger than 15-20 minutes, will be convenient in removing light debris. The vacuum cleaner is small in size, there is no power cord. Of the shortcomings can be noted a small capacity, the batteries must be recharged after each cleaning, the use time is limited.
Vacuum cleaner from the cigarette lighter - its power is morehigh, can be used with a thorough cleaning of the car interior. Unlimited running time, collects a variety of garbage. But such a vacuum cleaner is heavy and larger, there is a cord that can cause inconvenience in use.

Power. If the power of the car vacuum cleaner is maximal, then it is better to clean the car. On sale there are vacuum cleaners with a power of 30 to 180 watts.

Cord. The length of the cord is 2 and 3 meters, 2 meters is suitable for small cars.

Hose. The hose should be of medium rigidity, otherwise it will not fall into hard-to-reach places and you can not remove the garbage.

Dust collector. Dust bags are also different, it can be a bag that you need to snob after each cleaning in the cabin, or a washable container.

Tip 5: How to choose a battery for winter

The battery is a very delicate spare part. It is remembered mainly in the winter, when the car will start in difficult frosty conditions. Problems happen in other seasons, but the peak demand for batteries falls just for the winter.

You will need

- the instruction to the car;
- instructions to the battery.

Instructions

The first step is to read thecar operation. If the manufacturer strongly does not recommend the use of a certain battery with certain characteristics, then there is room for creativity. The main characteristic of the battery is its electrical capacity, which is estimated in Ampere hours. The more the battery capacity, the more electricity you can spend on starting the engine, that is, the longer the starter rotates. If your car is equipped with a solid electric package, and this is typical for modern cars, the extra 5-10 ampere hours will not prevent the battery.

It is worth paying attention to one more important point. The battery has a 100% efficiency at a temperature of + 27 ° C. However, if the air temperature is -18 ° C, the battery performance is reduced to 40%. At this time, to start the engine you need to have more than 2 times more energy, compared to a temperature of +27 ° C. In a cold climate, there is a need for large accumulators. Also, when choosing a battery, you should pay attention to its capacity. It shows the length of time in minutes, after which the battery gives 25 amps at + 27 ° C. There are some tricks in the operation of the battery.

After 2-3 years of use with batterythere may be some problems. In winter, at a temperature of -18 ° C, the battery is poorly charged due to the fact that the internal resistance increases. During short trips in winter, the energy that the battery spends on start-up can not be compensated. That is, if the car wound up and you drove 200 meters and muffled the car, the generator simply does not have time to fill the energy reserve that was spent for a cold start. The battery as a result functions on wear, faster discharges and fails.

It is worthwhile to carefully consider the filler plug. As you know, during the charging of the battery the water is evaporated from the electrolyte and decomposes during the electrolysis into oxygen and hydrogen. In order to evaporate the formed gases, a special hole is made in the plugs. In cheap batteries in traffic jams there is a simple hole, and in better instances something like a valve is mounted. The main thing that you need to decide when choosing a battery - in what conditions it is planned to operate the car and battery. For Russian winters it will be advisable to choose a larger battery, also do not forget to study the recommendations for a particular car.
