How to protect your battery from sulfation disease?

ABOUT battery sulfation heard by almost all motorists. This state batterywhen it is not able to charge with the usual charge mode. The main reason sulfation - non-compliance with the rules for using the battery.

If your Battery often and for a long time we stay in a discharged or semi-charged mode, a complexly soluble and sometimes insoluble is created inside lead large-crystalline sulfate. This, in turn, leads to a decrease in capacity and an increase in the internal resistance of the battery. At a strong stage sulfation blockage of pores is formed, as well as damage to electrodes.

Externally sulfation can be determined by the presence of large crystals or even a thin layer of lead sulfate on the battery. You can also determine the presence of a "disease" by the following signs:

1. Short battery life;
2. Decreased battery capacity;
3. An increase in the temperature of the electrolyte during charging;
4. Not taking charge, etc.

I will list a number of key reasons due to which sulfation can occur:

1. Strong battery discharges;
2. Application of electrolyte spoiled by impurities;
3. Permanent incomplete charging;
4. Reducing electrolyte levels;
5. Battery use at an unacceptably high temperature;
6. High density of electrolyte.

I will tell you what to do if you admit one of the listed reasons, and your battery has formed sulfation. A partial stage, which did not entail ruptures and damage to the electrodes, can be removed with the help of a long-term (more than a day) battery charge. It is necessary to charge the battery until the density and voltage stop at the same indicator for 5-6 hours. It is important to constantly monitor the level and density electrolyte.

If Battery stayed in a discharged state for a long time, the crystals could grow to their maximum size. In this case, it will no longer be possible to return the battery to its previous state.

The main thing that you can do to prevent this process is to stop undercharging the battery or charging it below 10.2 V. It is the prolonged stay of the battery in a discharged state that leads to sulfation.

Sometimes battery manufacturers offer special modes to prevent sulfation. In this situation, you must enable the required mode, and the system will control everything independently.

Remember that only the first stage of the disease can be cured. In advanced stages when the body Battery swelled up and lost more than 60 percent of its capacity, even a long-term charge will not fix the situation. Only changing the battery will help.

And most importantly, do not forget to regularly check the condition of the electrodes and carry out the training charge with small currents. This will significantly increase the service life. Battery.
