In order for the battery to always work reliably, monitor the level and density of the electrolyte in the cans. Top up evaporating distilled water to a level of at least 10 mm above the plates. If during the next density measurements it does not reach the specified values, then it is time to top up the electrolyte.
Necessary
Electrolyte or battery acid, distilled water, hydrometer, enema, beaker, safety glasses, rubber gloves
Instructions
Step 1
Before you finally decide what to add: distilled water or electrolyte, fully charge the battery with the charger. Then, using a hydrometer, measure the density in all jars and write down the readings on paper. Label the jars, for example, with a number and put down the density readings next to them so as not to be confused.
Step 2
If in a charged battery the density of the electrolyte in some banks differs from the norm (1.25 - 1.29 g / cm3), then it is necessary to make an adjustment: at increased density, it is necessary to increase the proportion of water; in case of a reduced value, add electrolyte or battery sulfuric acid solution.
Step 3
If the density of the electrolyte in the jar is within the normal range, and the level has dropped below the mark on the battery case, or as measured by a glass tube, it is less than 10 mm, just add distilled water.
Step 4
If in any jar the density is below the critical value (less than 1.20 g / cubic cm), take the solution out of it using an enema and pour it into a measuring cup. Record the reading of the volume, pour the electrolyte into the prepared glass container.
Step 5
Based on the values in the table, pour the required amount of electrolyte with a high density into a measuring cup and pour it into the jar using the same enema. In the case of a large difference in the direction of decreasing density, it is better to use battery acid with a density of 1.40 g / cc. cm. Bring the required level with distilled water.
Step 6
After bringing the density in all jars to approximately the same level, put the battery on a short-term recharge so that the solution is mixed. Measure the density again and repeat the operation if necessary.
