1. Disconnect negative and positive wires from the battery.
2. Remove a clamping level and take the battery from a motive compartment of the car.

1. Check a condition of plugs of the battery.
2. At connection of wires you monitor respect for polarity. The first connect and fix a positive wire.
3. Do not tighten a nut of terminal clips too hardly.
4. In order to avoid development of corrosion grease plugs and tips of wires with acid-free vaseline.

1. You watch purity of the battery and the surfaces surrounding it. Do not allow hit on the top part of the battery of dirt and moisture. In case of need carry out external cleaning of the battery:
   1. Remove the battery from the car;
   2. Carefully pour over the battery hot water, watching that it did not get inside through air vents of jellied covers;
   3. Carefully wipe the battery case.

3. Remove jellied covers and make sure of passability of air vents.
4. Check electrolyte level in banks of the battery, in case of need add the distilled water. Electrolyte has to hide plates completely. Do not overflow the battery, do not pour electrolyte from one banks in another.
5. If often there is a need for water addition, check the battery case for existence of signs of leaks. At detection of cracks replace the battery.
6. Whether by measurement of output parameters of the generator check not too battery charge level is high.
7. In order to avoid development of corrosion grease plugs with acid-free vaseline.
8. If as a result of an electrolyte modulation it got on the pallet of the battery and surrounding body panels, act as follows:
   1. Process the polluted surfaces soda bicarbonate;
   2. Wash away soda hot water - you remember that it soda violently reacts with water, causing plentiful foaming;
   3. After the termination of foaming rinse surfaces with clear water and let's them dry out;
   4. Remove the blown-up paint from the processed surfaces;
   5. Cover surfaces with anticorrosive paint.

1. Measure by the areometer battery electrolyte density (act according to the instructions attached to the device). Compare results of measurements to standard data:

Data are provided for electrolyte temperature 20 °C. On each 10 °C over 20 °C it is necessary to add to the specified values 0.007. On each 10 °C of decrease in temperature concerning 20 °C - to take away 0.007.

2. If the level of a charge of the battery is insufficient, it is necessary to make charging with use of one of the charger types which are available on sale:
1. Disconnect from the battery negative and positive wires (in that order);.
2. Check electrolyte level in banks, in case of need add the distilled water;
3. Remove jellied covers from the battery;
4. Further act according to instructions of manufacturers of the charger.
3. If after charging the battery does not provide due overall performance, it should be sent for check under loading with use of the special equipment to the next workshop on repair of automobile electric equipment. Check under loading in combination with measurement of specific weight will allow to estimate operability of the battery adequately.
