Checking the status of the battery, care it and gymnastics

Every year or every 20,000 km

Tools and materials needed to care for the battery.

1 - face shield / goggles - when removing brush corrosion acid crystallized particles can easily get into your eyes
2 - Baking soda - water solution of baking soda can be used to neutralize the corrosion
3 - acid-free Vaseline - applied to the battery terminals a layer of petroleum jelly to help avoid corrosion
4 - Device for stripping terminals / lugs wires - a device with a wire brush to remove all traces of corrosion from the battery terminals and wire end ferrules
5 - impregnated felt washers - installation of washers on each terminal of the battery directly under the tips of the wires will help prevent corrosion
6 - Puller - sometimes tips of wires is very difficult to remove from the battery terminals, even after a complete attenuation of nuts / bolts. This tool will help to remove the tips vertically without damage
7 - Device for stripping terminals / lugs wires - another type of stripping tool, a slightly modified version of paragraph 4, performing the same function
8 - Rubber gloves - another means of protection when working with battery; Remember that the battery is acid!

Inspection and Maintenance

When working with the battery should take certain precautions. The battery bank is always a highly flammable hydrogen, so in any case, do not allow approach the battery with a lighted cigarette or other forms of naked flame. Battery electrolyte is a solution of sulfuric acid, which if it enters the eyes or on the open areas of the body causing serious injury. In addition, the acid corrodes clothes and paints. When disconnecting the battery, always disconnect the negative cable first and connect it last!

Caring for the battery is very important as it allows to avoid the stops along the way due to its discharge. To perform the maintenance procedures require multiple tools.

PERFORMANCE ORDER

Before performing any maintenance always first switch off the engine and disconnect all electrical appliances, then disconnect the negative cable from the battery. If your car radio is equipped with theft protection, make sure that you have typed the correct code before disconnecting the battery. Usually NISSAN cars equipped with batteries that do not require special care. You can remove the covers of cans and refill with distilled water. The latest models can be equipped with batteries, require no maintenance, are completely sealed. Remove the lid and check the electrolyte level in each battery cans. It should be above the plates. Typically, each bank has a level indicator. If the electrolyte level is below normal, add only distilled water, and then close the lid cans. The electrolyte should be between the two lines on the outer side of the battery case. Left arrow shows where the steel plate is inserted to remove the filler plate. Check the electrolyte density using a hydrometer. Overflow cans can cause transfusion electrolyte during fast charge that will corrode and damage the nearest to the battery components. If the positive terminal of the battery wire and clamp your car equipped with rubber protector, make sure that it is not torn or damaged. He must completely cover the terminal. You should periodically inspect the external condition of the battery in the presence of damage such as cracks in the housing. Check the tightening clamps wires of the battery, providing a good electrical connection. Check each of the wires along the entire length for cracks and frayed insulation and wiring. If you find traces of corrosion (usually a soft touch white) Disconnect the, strip their special brush and reconnect. The appearance of corrosion can be minimized by installing specially treated washers, which are commercially available in auto parts stores, or by applying the clamps to the terminals and wiring layer of acid-free vaseline or grease after suitable connection. The corrosion of battery terminals is usually manifested in the form of light, fluffy powder. Disconnecting the wires from the battery terminals using the key - sometimes, in cases where corrosion is destroyed nut This procedure requires special pliers (always the first disconnect and connect the ground wire last!). Regardless of the type of device for cleaning the result should always be clean, shiny surface terminals. When stripping wire lugs is necessary to remove all traces of corrosion (the inner part of the tip has a taper follows the shape of the battery terminals, so do not remove too much material). Make sure that the battery tray is in satisfactory condition and bolt mounting bracket is securely tightened. If the battery was removed from the pallet (see chap. The electrical system of the engine, describes the procedures for removing and installing), make sure that during installation, it does not lay the parts or other foreign objects. When clamping fastening clamp bolt not tighten it too tight. Corrosion of the pallet, the battery case and the surrounding surfaces can be removed with an aqueous solution of baking soda. Apply the mixture with a small brush, let it stand and then rinse with plenty of clean water. The metal surface of the car, corroded, should be covered with zinc-based primer and then painted. For more information about the battery and the engine is started from an external source can be found in Chapter System of an electric motor and Section Starting the engine from the auxiliary power supply.

Charging

Manufacturers recommend to remove the battery from the car to charge it, t. To. The gas emitted during this procedure can damage the painted surfaces or the interior of the car, depending on the location of the battery. Quick charge with battery wiring can cause damage to the electrical system of the car.

PERFORMANCE ORDER

Remove all lids from cans batteries (if any), and close the hole with a clean cloth to prevent spillage of the electrolyte. Disconnect the negative battery cable and connect the charger cable to its terminals (positive to positive, negative to negative), then plug the charger into the network. If it has a switch, make sure it is set to "12 V". If your car radio is equipped with theft protection, make sure that you have typed the correct code before disconnecting the battery. If you use a charger with a current of more than two amps, regularly check the battery during charging, to make sure it is not overheated. Using a slow charger, you can safely leave the battery charge overnight after a regular inspection for the first two hours. When charging batteries, maintenance-free, it can take certain precautions (eg, use of a very low current charger). In such a battery could be a warning label, but if it does not, consult your NISSAN dealer branch of an electrician or a garage. If banks have a removable battery cover, every hour for the last few hours of the charging cycle, check the electrolyte density using a hydrometer. Cheap hydrometers are available in auto parts stores - in their application, follow the attached instructions. The battery can be charged to consider if a two hours performance density of its electrolyte does not change, and the electrolyte in the banks free bubbles. The density of the electrolyte in individual banks should be almost identical. If this is not so, then one or more cans of the battery out of order and should be replaced. Some maintenance-free batteries are at the top of the built-in hydrometer having a window - the color indicator of the battery charge. Usually brightly colored window indicates that the battery is fully charged, and the dark color indicates the need for additional charge. More detailed instructions are given in the instructions of the manufacturer of the battery. If the battery is sealed and does not have the built-in hydrometer, you can check the charge level using the battery terminals connected to a digital voltmeter. A fully charged battery will more and 12.6 volts. For more information about the battery and start the engine from the auxiliary power can be found in Chapter System of an electric motor and Section Starting the engine from the auxiliary power supply.
