A battery is an essential part of your vehicle. When left unchanged or not fully charged for long periods of time, deposits of lead sulfur form on the lead plates and harden over time, inhibiting the performance of the battery. This situation calls for a battery desulfator, which restores the battery to full capacity, thus increasing its performance and durability. Below are some of the best battery desulfators on the market.

    Tips

    • Keep your battery fully charged to prevent sulfation. A lead plate battery should be charged 14 to 16 hours each time.
    • Sometimes sulfation can result in permanent damage to your battery. It is advisable to check the water level of your battery frequently. If the water level is below the plate, then critical sulfation has occurred.
    • When shopping for a reliable desulfator, consider if it has a testing kit, high-frequency current, monitoring indicator, and lead battery charger. 

    FAQs

    Q: What is desulfation?

    A: When you frequently drive at low speeds or don’t drive at all, the battery does not acquire a full charge. Consequently, sulfate crystals form on the lead plates, inhibiting the performance of the battery. This process is known as sulfation. Desulfation is the removal of these sulfate crystals through a gadget called a desulfator.

    Q: How does a battery desulfator work?

    A: It works by sending electric pulses through the battery, and the sulfate comes off the lead plates. The sulfate dissolves in the acid, making the battery regain its full capacity.

    Q: How long does it take to desulfate a battery?

    A: It depends on the efficiency of your desulfator and the amount of sulfate that has formed on the battery. Keep your battery charging until you see a significant improvement. Sometimes the process takes up to a week.
