Check of a condition of the battery, care of it and charging Tools and materials necessary for care of the batteryCheck and leaving
1 Care of the battery is very important procedure allowing to avoid stops in way because of its discharge. Implementation of the procedure of service requires several tools. On cars with the 4-cylinder petrol engine the battery settles down in a motive 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 procedure of service always at first switch off the engine and switch-off all electric devices, then disconnect a negative wire from the battery.
3 Your car is equipped with the battery which is not demanding leaving. It is possible to uncover cans and to add the distilled water. Some models can be equipped with the batteries which are not demanding leaving at all which are completely sealed. 4 Uncover and check electrolyte level in each of battery cans. It has to be above plates. Usually on each can there is an index of level. If the level of electrolyte is lower than norm, add only the distilled water and then close covers of cans.
5 If the positive plug and a collar of a wire of the battery of your car are equipped with a rubber protector, make sure that it is not torn and is not damaged. It has to close the plug completely. 6 It is necessary to examine periodically an external condition of the battery on existence of such damages as cracks in the case. 7 Check reliability of tightening of collars of wires of the battery providing good electric connection. Check each of wires on all length for existence of cracks and attritions of isolation and wires. 8 At detection of traces of the corrosion (which is usually representing a friable raid of white color) disconnect wires from plugs, smooth out them a special brush and again connect. Emergence of corrosion can be minimized by installation of specially processed washers which are available on sale in shops of auto parts, or by drawing on plugs and collars of wires of a layer of acid-free vaseline or suitable lubricant after their connection. 9 Make sure that the pallet of the battery is in satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery was removed from the pallet (address materials of the Section Removal and installation of the rechargeable battery), track that in installation time on it details or other foreign objects did not lie. At a latching of a fixing collar do not tighten its bolt too hardly. 10 Corrosion traces from the pallet, the case of the battery and surrounding surfaces can be removed by means of water solution of baking soda. Apply mix with a small brush, let's it stand and then wash away plentiful amount of clear water. 11 The metal surfaces of the car which underwent corrosion should be covered with primer on a zinc basis and then to paint. Charging
13 Remove all covers from battery cans (if they are available) and close openings pure rags to prevent an electrolyte spillage. Disconnect a negative wire of the battery and connect charger wires to its plugs (positive to positive, negative to negative), then turn on the charger in network. If it has the switch, make sure that it is installed in situation "12 volts".
14 If you use the charger with current more than two amperes, regularly check the battery during charging to make sure that it did not overheat. Using the slow charger, you can quietly leave the battery to be loaded on all night long after regular check within the first two hours. When charging batteries, not demanding leaving, certain precautionary measures can be required (for example, use very much of the low-ampere charger). On such battery can be precautionary шильдик, but if it is absent, address for consultation in representative office of BMW or the electrician from auto repair shop. 15 If banks of the battery have removable covers, each hour within the last several hours of a charging cycle check electrolyte density by means of the areometer. Inexpensive areometers are available on sale in shops of auto parts - at their application follow the enclosed instructions. The battery can be considered loaded if within two hours indicators of density of its electrolyte do not change, and electrolyte in banks freely bubbles. Electrolyte density in separate banks has to be almost identical. If this not so, so one or several cans of the battery failed and they should be replaced. 16 Some batteries which are not demanding leaving have above the built-in areometer having a window - the color indicator of extent of battery charging. Usually brightly painted window means that the battery is completely charged, and dark color testifies to need of additional charging. More exact instructions are provided in the instruction of the manufacturer of the battery. 17 If the battery is sealed and has no built-in areometer, you can check charging degree by means of the digital voltmeter connected to plugs of the battery. Completely charged battery will show 12.6 and more than a volts. EACH 2 YEARS, IRRESPECTIVE OF THE RUN |
