Speaking about the need to increase the density of the battery, we, of course, mean the density of the electrolyte in the batteries. I turned the key two or three times, and that's it - the starter does not turn. Especially if the ignition is not adjusted.
Necessary
- - hydrometer,
- - electrolyte,
- - Charger
Instructions
Step 1
In such cases, first of all, check if your battery is sufficiently charged.
If it has been stored for a long time, removed from the car, it is quite possible that the battery has lost its charge. This phenomenon is called self-discharge. Loss of battery charge can also occur on a vehicle in use in a certain driving mode.
As the battery charge decreases, so does the density of the electrolyte. These two indicators are closely related. Put the battery on charge and you will increase the density. Don't forget to open the plugs.
Note that the less current you charge your battery, the more fully and deeper you charge the battery. For "55", for example, the optimal current will be 2.75 A.
Step 2
Check the density of the charged battery. If, after 10-12 hours, its density has not reached the readings of 1.27 - 1.28 g / cu. cm, you did not observe boiling and gas evolution from the battery cans - proceed to increasing the density by adding fresh electrolyte.
To do this, taking all precautions with a rubber bulb or the same hydrometer, take the electrolyte from each jar in turn and pour it into some glass container. In order not to waste fresh electrolyte, take and pour, depending on the loss of density, several suctions from the jar at once.
Step 3
Replenish the volume with prepared fresh electrolyte with a density of 1.4 g / cc. cm and measure the changing density periodically. Strive for equal performance across all battery banks.
At the end of the operation and final measurements, the electrolyte in the jars must be mixed. To do this, put the battery back on low-current charging, without letting it boil. The electrolyte will also mix in the battery installed on a car with a running engine.
