How to recondition any lead-acid battery?

How to recondition any lead acid battery
batteries lead acid

The most common type of battery in cars, motorcycles, and other heavy machines is a lead-acids battery.

It is one of the oldest rechargeable batteries. It consists of Lead plates and Sulfuric Acid in electrolytes. The production of electricity is based on a chemical reaction between these battery plates and acid solution.

The Sulfuric acid in the electrolyte reacts with the Lead oxide (PbO) and Lead (Pb) to form lead sulfate (PbSO4). This lead sulfate is the main reason a battery becomes dead. The reversal of this process is called desulfation. For the desulfation, a number of methods are being used. Some are more effective while some are very expensive.

The following steps are taken to desulfate a dead battery.

  • Step 1: Prepare the E-Salts + distilled water, electrolyte. For this take about 4 big spoons of pure Epsom Salt and one liter of distilled water. Heat up the water just below the boiling point for some time. Then add the Epsom salt and dissolve it. ( Get this 100% pure salt )
    Epsom Salt 100% Pure Magnesium Sulfate
  • Step 2: Remove the battery caps, and completely pour out the old electrolyte. Then, add the new electrolyte and distribute it gently. So there should be no gap for air.
    filling epsom salt distilled water in flooded battery
  • Step 3: Charge the battery with high Amp charging settings. This process will take some time depending on the extent of sulfation. But every second worth it. Next, set the charger at a low Amp setting and charge the battery until full. ( get this smart and advanced charger )
  • Step 4: Now discharge the battery, and recharge it again using low Amp settings. The low current helps Epsom salt slowly beaks down the lead sulfate deposits on the battery. You can repeat the charging-discharging process up to 5 times. In the last, you’ll get an extended battery.

This method is useful for acid+lead batteries, like 6 volts, 12 volts, 24 volts, OR regular battery, deep cycle battery, golf cart, OR car, motorbikes, tractors, and other vehicles.

You should always check your refurbished battery with a battery load tester to do a load test.

There is one other solution + enhancer that helps protect new batteries from sulfate deposits and dead batteries to desulfate. That is the INOX mx2 battery solution.

The INOX mx2 solution can be added to a new one, to improve battery performance. It can also be added to an old battery or even dead batteries to desulfate them.
