BLS36A BLS Battery Saver Desulfator Charger Maintainer

Review BLS Battery Life Saver 36v Desulfator Charger Maintainer Tested Used

The BLS BLS-36A 36V Desulfator Charger Maintainer is an essential tool for extending the life of your lead-acid batteries. This versatile device is designed to maintain, charge, and desulfate 12V, 24V, and 36V batteries.

The desulfating feature of this charger is particularly noteworthy. Over time, lead-acid batteries can develop sulfation, a condition where sulfate crystals form on the battery plates. This process reduces the battery's capacity and efficiency. The BLS BLS-36A Desulfator Charger Maintainer utilizes a patented desulfating technology, which sends a series of corrective currents through the battery to dissolve the sulfate crystals and restore the battery's performance.

This 36V charger is also a high-efficiency charging solution. It automatically detects the battery type and adjusts the charging parameters accordingly. The charger delivers a three-stage charging process: bulk, absorption, and float. During the bulk charging stage, the charger delivers a high current to charge the battery quickly. In the absorption stage, the charger maintains a constant voltage to ensure the battery is fully charged. Lastly, during the float stage, the charger maintains a constant voltage and a reduced current to keep the battery at full charge.

The BLS BLS-36A Desulfator Charger Maintainer is built with durability in mind. It features a rugged, water-resistant design, making it suitable for use in various environments. The charger is also equipped with short-circuit, overcharge, and reverse polarity protection to ensure the safety of the user and the battery.

Designed for ease of use, the BLS BLS-36A Desulfator Charger Maintainer features an intuitive LED display that shows the charging status. The charger also has a built-in thermal manager to regulate the temperature during the charging process.

In summary, the BLS BLS-36A 36V Desulfator Charger Maintainer is a powerful and versatile tool for maintaining and restoring the performance of lead-acid batteries. Its desulfating technology, high-efficiency charging, rugged design, and user-friendly features make it an ideal choice for various applications, including industrial, automotive, marine, and renewable energy systems.

The BLS BLs36A battery saver, desulfator, charger, and maintainer is a multifunctional device designed to extend the life of lead-acid batteries by preventing sulfation and providing a trickle charge.
