Gymnastics of the storage battery

Points 6, 11-14 do not concern to малообслуживаемым to storage batteries with which cars BMW of 5th series are equipped. It is necessary to observe recommendations about operation малообслуживаемых batteries.

Never on close the storage battery накоротко, i.e. Do not connect among themselves (+) and (-). At short circuit the battery can overheat and burst. Do not shine the battery with an open flame. The electrolit is poisonous, do not suppose its hit in eyes, on a skin or clothes. At electrolit hit plentifully wash out the amazed place water.


1. Before battery gymnastics disconnect from it positive (+) and negative (-) cables. At first the negative cable is disconnected.
2. Before battery gymnastics check up electrolit level, if necessary add electrolit.
3. If the battery has frozen, before a charge give the chance to it to thaw. The charged battery freezes at temperature - 65С, the semicharged battery freezes at temperature - 12С.
4. If the battery long time has been discharged, completely it cannot be charged or in general it is impossible to charge. In this case to charge the battery it is necessary a small current during longer time. After a charge it is necessary to check up electrolit density.
5. Before a battery charge check up its pressure, address to Section Check of the storage battery.
6. Turn out from the battery of a stopper and put them on apertures. It will exclude hit of splashes of electrolit on a paint and varnish covering, providing simultaneously possibility leaving gases formed at a charge.
7. Charge the battery only in well aired premise. At a charge of the battery established on the car open a luggage carrier cover.
8. At normal gymnastics the current makes about 10 % of capacity of the battery. (At capacity of 50 Ach the charge current makes, thus, 5). Charge time approximately makes 10 hour.
9. A positive pole of the battery (+) connect to a positive pole (+), a negative pole (-) with a negative pole (-) зарядного devices.
10. The electrolit temperature at a charge should not exceed +55С. Otherwise interrupt process or lower value of a current of a charge.
11. The battery gymnastics should be spent until gases and also density of electrolit and pressure are allocated do not increase during three gaugings following one after another with an interval at 1 o'clock.
12. After gymnastics check up electrolit level, if necessary add the distilled water.
13. Check up electrolit density. If the electrolit density in one of sections essentially differs from density in others (for example, in five sections density makes 1.26 g/ml, and in the sixth section 1.18 of g/ml) the battery is faulty and should be replaced.
14. Allow to leave during 20 mines to gases, then close stoppers.

It is impossible to start the engine at the disconnected storage battery.
