Battery – a relatively simple part of the car does not require special care, but it becomes sensitive when a cold winter morning, you try to start the car and the battery says ” NO! ” . In order to avoid such things , it is better in advance to anticipate problems . Here are some tips on how not to be in trouble in winter.
Are you sure the battery is to blame?
Often the car ignition problems during the winter is not due to the battery. It – only the consequence of failure. Usually batteries are already on the “death” limit for tidy wiring or a malfunctioning generator or called voltage relay-regulator.
Usually it is sufficient to start the car 40 percent. battery power. In winter, when the air temperature falls well below zero, the battery capacity is reduced, and if it is fully charged, the power to start the engine stiff enough. So what to do?
First, before the start of the winter, we advise you to check the battery voltage. If you turn off the car engine and all electrical appliances battery voltage should be about 12.7 V. If the voltage is lower – in the winter waiting for trouble. But, do not immediately throw away a battery – usually enough to fully recharge.
When you turn on the engine and at about 1500 to 2000 rpm., The voltage should be between 13.8 to 14.5 V. The voltage should not change strongly turn on the lights or other electrical devices. If it is too small, it is not the fuel cells, a generator or transducer – controller, which means that the battery is not being charged fully. Sometimes the tension is even greater, but it is also dangerous – risk of battery “boil”, it turns into a liquid gas, and in some cases, batteries may simply explode!
The generator can fully recharge the battery, and for other reasons. For example, if the car a powerful built-in stereo sound, it uses much more energy than it generates generator. Therefore, the battery is running out of juice.
What kind of battery to buy?
Wrong to think that when you purchase a more powerful battery resolve problems.
Battery describes one of the main parameters – its capacity, which is measured in ampere hours (Ah).
Manufacturers recommend the car to install a certain capacity of the battery. Specialists advise to install more than 10 percent. more capacious battery. For example, if the manufacturer recommends the use of 55 Ah, this is a larger capacity than 60 Ah battery mount do not recommend. The reason is simple – the car calculated generator to recharge some battery capacity and larger just can not charge fully, i higher capacity becomes meaningless. Unless install and more powerful generator. In addition, the starter since it will not be more powerful – he will use only the power that complies with the technical requirements.
Batteries come in three types – serviced, partially served and not served. We recommend buying the past. Although they are a bit more expensive, but they do not require absolutely no maintenance. Those who like to “live” in the garage, can buy the battery serviced – the less expensive, but it requires constant maintenance (checking the electrolyte level, add fluid).
For trouble guilty and dirt
Often, due to troubles in the winter guilty and simply untidy wiring or just dirt . So before frost we recommend some simple work that later winter mornings will feel at ease.
First, inspect the battery terminals – they have to be clean and neaprūdiję and screws wires screwed on tightly .
Often, the battery current “stealing ” irregular electrical appliances, for example , all the while acting on the trunk light . Maybe messy cable with damaged insulation.
Cluttered high-voltage wires, dirty contacts and the layer of dirt in the engine compartment – all of which can have an impact on that part of the energy wasted.
The city drivers are at higher risk
If you drive a car rarely or for short distances , the generator fail to charge the battery . This is especially true in winter, when it comes to not only turn on the lights , but also full capacity to act in the heating system and other devices. Therefore, it is recommended at least once a year ( preferably before the winter) and remove the battery fully charged at home or workshop . This is an inexpensive service that can save you a lot of time and nerve cells in the future.
In winter, when starting the engine consumed electricity normally -functioning car restored in just about 20 minutes of engine operation . But remember that at one time turned the entire car electronics consume several times more power than the generator generates . Therefore, running on very short distances sometimes recommend to bundle heating at full capacity , that evening from work would return to public transport.
A few more tips
The greatest enemy of the battery – forgetfulness. Left the light on the battery discharges within a few hours.
Check the condition of the battery manufacturers recommend every oil change.
If the battery is completely discharged, charge it as soon as possible – the discharged battery begins an irreversible process, its capacity decreases rapidly and after a while even full immersion longer appropriate. This is particularly important in the winter, because the battery is discharged quickly freezes, ice crystals formed and dismantles inside the plates.
And at the end of the tip, where the car nebeužsiveda you try to start the wire the vehicle battery. First, connect the positive pole, but then negative. Another car’s engine should be turned off, because it can burn your car’s engine control processor. After starting the engine, disconnect the cables in reverse order – first disconnect the negative pole, and only after a positive.
