Check of a condition of the battery, care it and gymnastics

Tools and the materials necessary for care by the battery

1 — obverse guards/goggles - at removal by a brush of traces of corrosion of a particle of crystallising acid can easily get to eyes
2 — baking soda - the water solution of baking soda can be used for corrosion neutralisation
3 — бескислотный vaseline - put on plugs of the battery the vaseline layer will help to avoid their corrosion
4 — the adaptation for зачистки plugs/tips of wires - such adaptation with a wire brush will remove all traces of corrosion from plugs of the battery and tips of wires

5 — the impregnated felt washers - installation of such washers on each plug of the battery directly under tips of wires will help to avoid corrosion
6 — the stripper - sometimes appears to be removed tips of wires very difficultly from battery plugs, even after full easing of nuts/bolts. This tool will help to remove tips vertically upwards without damages
7 — the adaptation for зачистки plugs/tips of wires - one more type of the smoothing out tool, slightly changed variant of point 4 which are carrying out the same functions
8 — rubber gloves - one more protection frame at work with the battery; remember that in the battery there is an acid!

Check and leaving

At work with the battery it is necessary to undertake certain security measures. At battery banks always there is extremely an inflammable hydrogen, therefore at all do not suppose approach to the battery with the lighted cigarette or other kinds of open fire. The battery electrolit represents a solution of sulfuric acid which at hit in eyes or on open sites of a body causes serious traumas. Besides, acid corrodes clothes and paints. At battery switching-off always the first disconnect a negative wire, and connect it in last turn!

1 Care of the battery is very important procedure, allowing to avoid stops in a way because of its discharge. For performance of procedure of service some tools are required. On cars with the 4-cylinder petrol engine the battery settles down in an impellent compartment, on cars with the diesel and 6-cylinder petrol engine the battery settles down in a luggage carrier behind on the right under a cover.
2 Before the beginning of procedure of service always at first switch off the engine and disconnect all electrodevices, then disconnect a negative wire from the battery.

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

3 your car is equipped by the battery which is not demanding leaving. It is possible to remove covers банок and to add the distilled water. Some models can be equipped by the batteries which absolutely not are not demanding leaving which are completely sealed.
4 Remove covers and check up electrolit level in each of банок batteries. It should be above plates. Usually on everyone bank there is a level index. If level of electrolit below norm, add only the distilled water and then close covers банок.

Overflow банок can lead to transfusion of electrolit during the accelerated gymnastics that will cause corrosion and damage of the components nearest to the battery.

5 If the positive plug and a collar of a wire of the battery of your car are equipped by a rubber protector, make sure that it is not torn and not damaged. It should close the plug completely.
6 It is necessary to examine periodically an external condition of the battery on presence of such damages, as cracks in the case.
7 Check up reliability of a tightening of collars of wires of the battery, providing good electric connection. Check up each of wires on all length on presence of cracks and attritions of isolation and wires.
8 At detection of traces of corrosion (usually representing a friable touch of white colour) disconnect wires from plugs, smooth out their special brush and again connect. Corrosion occurrence can be reduced to a minimum by installation of specially processed washers which are available on sale in shops of autospare parts, or by drawing on plugs and collars of wires of a layer бескислотного vaseline or suitable greasing after their connection.

9 Make sure that the battery pallet is in a satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery acted in film from the pallet (address to materials Has undressed Removal and installation of the storage battery), track, that in an installation time on it details or other extraneous subjects did not lie. At зажимании a fixing collar do not tighten its bolt too hardly.
10 Traces of corrosion from the pallet, cases of the battery and surrounding surfaces can be removed by means of a water solution of baking soda. Put a mix a small brush, allow to it to stand and then смойте plentiful quantity at its finest.
11 Metal surfaces of the car, подвергшиеся corrosion, it is necessary to cover with a first coat on a zinc basis and then to paint.


Manufacturers recommend to remove the battery from the car for its gymnastics since the gas allocated during this procedure, can damage the painted surfaces or a car interior, depending on a battery arrangement. The fast gymnastics with the connected wires of the battery can lead to damages of electric system of the car.

13 Remove all covers with банок batteries (if they are available) and close apertures pure rags to prevent an electrolit spillage. Disconnect a negative wire of the battery and connect wires charger devices to its plugs (positive to positive, negative to negative), then include зарядное the device in a network. If it has the switch, make sure that it is established in position “12 volt”.

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

14 If you use зарядным the device with a current more than two amperes, regularly check the battery during gymnastics to make sure that it has not overheated. Using slow зарядное the device, you can easy leave the battery to be charged on all night long after regular check within first two hours. At gymnastics of the batteries which are not demanding leaving, certain safety measures (for example, application very much низкоамперного charger devices) can be demanded. On such battery can be precautionary шильдик but if it is not present, address for consultation in representation branch BMW or to the electrician from a repair truck.
15 If battery banks have the demountable covers, each hour within last several hours charger a cycle check density of electrolit with the help hydrometerа. Inexpensive hydrometerы are available on sale in shops of autospare parts - at their application follow applied instructions. It is possible to consider the battery charged if within two hours indicators of density of its electrolit do not change, and the electrolit in banks freely bubbles. The electrolit density in separate banks should be almost identical. If this not so, means, one or the several банок batteries have failed also them it is necessary to replace.
16 Some batteries not demanding of leaving have above built in hydrometer, having a window - the colour indicator of degree of gymnastics of the battery. The usually brightly painted window means that the battery is completely charged, and dark colour testifies to necessity of additional gymnastics. More exact instructions are resulted in the instruction of the manufacturer of the battery.
17 If the battery is sealed and has no built in hydrometerа, you can check up degree of gymnastics by means of connected to plugs of the battery of the digital voltmeter. Completely charged battery will show 12.6 and more volt.
