Density of electrolyte decreases at an accumulator discharge where it is filled in. To lift its density, try to charge the accumulator before boiling in banks. If after that density of electrolyte did not rise to the necessary indicator, make in it room and add sulfuric acid.
It is required to you
- the areometer, sulfuric acid or the concentrated electrolyte, the charger.
Instruction
1. The electrolyte density raising without filling-up by kislotypervy sign of falling of density of electrolyte is an accumulator discharge. To determine density, use the areometer. For this purpose with its help delay a number of electrolyte and determine its density by the emerging floats. It has to make 1.27 g/cm3, in the winter it can be slightly higher. If density of electrolyte is less than norm, connect the accumulator to the charger and load it until electrolyte in banks does not begin to boil. Then discharge it by means of a bulb, during this time measure current of a discharge and its time. Having multiplied these values, learn the capacity of the accumulator and compare it to passport. If it is more than 30% less, then the recharge will not help. In the return case charge the accumulator again and measure electrolyte density. It has to return to normal.
2. The electrolyte density raising kislotyv that case if the first method did not help, and density of electrolyte remains filling-up less than 1.27 g/cm3, add acid. For this purpose the areometer delay a number of electrolyte and fill in sulfuric acid. Consider that its density is 1.83 g/cm3, and this very caustic substance. In autoshops the concentrate of electrolyte with a density of 1.4 g/cm3 is on sale - it is safer therefore use it better. Add a concentrate until density increases to the necessary value. After that put the accumulator on charging with small current (no more than 2 A) for half an hour. During this time electrolyte completely will mix up. Again check density in all banks. It has to be identical and meet standards. If density is still small, repeat operation again.
3. Observe extra care during the work with sulfuric acid. Do not allow its hit on skin or clothes. If it occurred, wash away electrolyte a large amount of water and process this place solution of soda which neutralizes acid. At solution procrastination do not overturn at all the accumulator because slime from plates can short-circuit the battery, and it will deteriorate.
