Advice 1: How to connect a car battery

Surely every car owner faced with problems related to the battery. The battery should be regularly recharged. You need to know how to remove and install. Also, you must know all safety rules of work with the battery.
How to connect a car battery
Instruction
1
Before you install a car battery, you need to check its charge. If the battery is low and need to charge it. In order to charge the car battery, you must have a charger. You need to properly connect the battery and charger. Clip the positive pole needs to be fixed at the positive pole, and clip the negative pole to negative. Then turn on the charger.
2
In order for the charging function correctly, you must configure the capacity of the charging current to 1/10 of the twenty-hour capacity. For example, if a 100 Ah battery, it needs to be charged at 100 Ah/10. The charging process takes around 14 hours. It all depends on how discharged the battery is. After the charging process is completed, you need to disconnect the charger. Disconnect the clips from the poles. First you need to disconnect the negative pole clamp, and only then the positive pole.
3
When using the battery, you must observe the safety rules. When charging is allocated a mixture of hydrogen and oxygen is explosive. Battery do not tilt more than 45°. May occur leakage of the electrolyte. The electrolyte is a corrosive liquid. If electrolyte gets on your skin, you should immediately seek medical help.
4
You need to take seriously the connection of the rechargeable battery. The battery connection to the vehicle network should be automatically disabled consumers. The battery has two poles – positive and negative. From the network of the car there are two wires. The black wire indicates the positive pole, and red is negative. The first thing you need to attach the wire to the positive terminal and then negative. Be careful not to confuse the poles, otherwise there will be a circuit, which can easily cause damage to the battery or damage to the vehicle network.
5
Battery must be securely mounted in the normal socket of the car. Terminals need to tightly clamp onto the poles of the findings. The wires should be in a loose condition.

Advice 2: How to connect a battery

On older cars it was possible to do without the battery: the engine is started with the pusher or handle. On modern vehicles are too many smart electronics, which without power will simply not allow the engine to start. Therefore, bringing the iron horse to life after the winter vacation, do not forget to properly connect the battery and check its voltage.
How to connect a battery
Instruction
1
The main function rechargeable battery or battery in a car is start the engine. In addition, he is the source of power for various electrical devices: lights, heating, radio, alarm, fan heater and other when they are used with the engine off. To connect the battery, open the hood of the car and lock the support leg.
2
Inspect the installation site of the battery. Wipe it from dirt, dust and debris. The battery should fit up in the seat.
3
Inspect wire terminals and battery terminals. If they are covered with the oxide layer, and clean them. On the terminals after cleaning apply dielectric grease.
4
Install the battery pack. Connect to the battery terminals wires. First connect the wire to the positive, the positive output of the battery. Connect the second wire to the negative terminal.
5
If the car has any locking battery elements, for example, hold-down brackets, install them in suitable places and attach corresponding nuts of fasteners. Check up reliability of installation of the battery.
6
To check the correct installation of battery, switch on lights or other appliances. Their work will be an obvious sign that you have successfully coped with the task to connect a battery.

Advice 3: How to charge a car battery

Automotive rechargeable battery (hereinafter, battery) — auxiliary source of energy for cars and trucks, motorcycles, and electrical engineering. Currently, for passenger cars use a battery voltage of 12 volt lead-acid type. If the battery can not provide the engine start-up, it needs to be charged.
How to charge a car battery
You will need
  • - AKB;
  • charging-starting device;
  • - wrenches or sockets (10mm for the battery terminal, the other dimensions — for fixing battery);
  • - a metal file or sandpaper, and a voltmeter or tester would be an advantage;
  • - served for battery may need a hydrometer and distilled water.
Instruction
1
Turn the ignition off and disconnect all electrical equipment. With the help of wrench or sockets 10mm loosen the negative first, then positive terminal on the battery electrode.
2
Depending on the car model the battery can be fixed on top, bottom, or not attached at all. Identifying the type of fastening of the battery, loosen the bolts holding the mounting bracket. Loosen and remove the battery. Carry it carefully, without turning, to prevent leakage of electrolyte.
3
Select a suitable location for charging the battery. Charger (memory) or battery must be on level solid surface. It is desirable that the room was ventilated and inaccessible to children. Charging should occur away from open flame. Close rechargeable battery no Smoking, and no spark. Wipe the battery clean of dirt. Inspect the lead electrodes in the presence of oxidation gently clean them with a file or sandpaper until the surface is shiny and bright for best conductivity.
4
If the battery is serviceable, remove the bar from the top and carefully remove the six plugs underneath. Measure the electrolyte level. Add distilled water to the desired level (1-1,5 cm above the lead plates). If the charger instruction throughout follow its instructions. Connect the terminals of the charger to the electrodes of the battery, strictly observing polarity. Depending on the memory model you may need to set the voltage toggle switch in the on position 12V and 24V, in accordance with the battery voltage.
5
Turn on plug the device into the socket. If there is a rheostat to vary the power current, install it in such a position that the ammeter showed a current equal to one tenth of battery capacity (e.g., for battery of the car VAZ 55A/h need charge current of 5.5 A). As the battery is charging, the current will weaken. Try to check this figure every two hours and, if necessary, increase the current using the rheostat. Model memory with automatic switch will stop charging when the desired voltage.
6
To determine the degree of battery charge, you can use the following methods. Measure the voltage with a voltmeter (tester). The accepted battery you can measure the electrolyte density with a hydrometer. Grounds for termination of the charging can be 12-16 volts voltage or electrolyte density of 1.25-1.3 kg/l. With open jams of the sections of the battery can start the release of gas and "boiling" (a characteristic gurgling) of the electrolyte is also a signal of readiness of the battery.
7
When charging ends, unplug the charger, remove the terminals from the battery electrode, assemble its parts and, if necessary, reinstall.
Note
The drop of battery voltage can be caused by prolonged inactivity of the car, low air temperature, age of the battery, a ground of the electric circuit of the car, lack of electrolytes and other reasons.
When removing the terminals from the electrode long key please use caution when dismantling one terminal to touch the other, a short circuit occurs.

Electrolyte — a mixture of sulfuric acid and water is particularly aggressive and toxic liquid. Avoid spilling electrolyte on the skin. In case of contact with eyes immediately rinse thoroughly with water.
Useful advice
If the polarity symbols AKB indistinguishable (dirty wiped) note that the positive electrode always more negative in a diameter of about 2 mm.
You can conduct a "preventive" recharging the car battery once a year (e.g. in early winter when the first frost) on low current — 0.1, 0,025-0,05 the capacity of the battery.
