188.8.131.52. Check of level of electrolyte
At the low level of electrolyte the capacity of the rechargeable battery decreases and it is quickly discharged.
|Fig. 1.184. Check of level of electrolyte of the rechargeable battery
Check electrolyte level in the rechargeable battery of times a week. If electrolyte level in the battery low, uncover accumulators and add necessary amount of the distilled water. Level of electrolyte has to settle down between the lower and top tags on a wall of the case (fig. 1.184)
Do not pour the distilled water above the top tag.
Check electrolyte density in the rechargeable battery by means of a hydrometer. Maintenance of the required density of electrolyte is especially important in cold season. If electrolyte density low, charge the rechargeable battery.
