6.1.3. Check of level of electrolit
Electrolit level should be on 5–10 mm above the top edge of separators and not rise above a bottom edge of a jellied mouth.
At operation of the battery electrolit level gradually goes down, as the water entering into its structure evaporates. For restoration of level of electrolit add only the distilled water.
If it is precisely established that the reason of low level is выплескивание add electrolit of the same density, as remained in a battery element.
If level above norm suck away electrolit a rubber pear with эбонитовым a tip.
