Charged state. To control the charged state, you need a device for lifting and moving acid. To control, unscrew the plugs and insert the sharp end of the device into the hole of the rubber overfill protection device. Use a rubber ball to suck up enough acid to allow the float to float freely. Depending on the charged state, the specific gravity of the acid has a different value, characterized by the degree of immersion of the melt in the acid. At a dive level of 1.28, the battery is fully charged; at a level of 1.12, it is completely discharged. Intermediate indicators show the corresponding strength of the charged current. The readings on the acid lifter are programmed in kg/l.
Battery charge. A highly charged battery should only be filled with distilled water after charging. When charging, the acid level rises and for this reason, a battery filled according to the instructions could be «transfuse». The charging current should not initially exceed 10% of the battery capacity. Depending on the design of the battery charger used, the charging current gradually decreases automatically, the battery is fully charged if the density of the acid does not change over the next two hours.
The battery caps are usually supposed to be unscrewed and placed over the filling holes so that the explosive gas produced by mixing oxygen and hydrogen can escape. Since splashing of acid is inevitable during fast charging, the area around the battery should be covered with newspapers or the like. If charging is carried out indoors, it must be well ventilated. Never light the openings of the battery with an open flame.
When using a household charger, you can leave the battery in the car. It is also not necessary to insulate the cable, the situation is quite different when using a quick charger. Disconnect both battery cables so as not to damage the three-phase car alternator diodes, electronic switching devices, autoradio, etc.
Mounting and dismantling. The battery is located in the engine section and is screwed to the console. Before dismantling, unscrew both battery cables from the poles. Always disconnect the negative cable first.
Pier montage «native» batteries, first clean the pole pieces and coat them with a suitable lubricant. Connect the positive cable first and tighten it tightly.
Starting from a blank battery. It is easiest to use charter cables; however, they must have a strong cross-section and strong clamping terminals in order to pass current from one battery to another. When buying such cables, you should not be stingy and purchase a copper cable. Although aluminum cables are cheaper, they overheat, which can melt the insulation and burn your fingers when trying to remove the terminals. First connect the positive cable to both positive cables, and only then connect the negative cable. Your assistant should start the engine, let it run at medium speed. so that the car alternator can use up the extra current.
