Lishi DJM12150 maintenance free lead-acid battery 12V150AH UPS power storage battery

Description :

The LEOCH DJM series maintenance free sealed lead-acid batteries are designed specifically for backup power systems that require high reliability, long lifespan, and low maintenance costs. This model DJM12150 has a nominal voltage of 12V and a rated capacity of 150Ah (20 hour rate), suitable for scenarios such as UPS uninterruptible power supply, communication base stations, data centers, emergency lighting, solar energy storage systems, and industrial control equipment.

The product adopts a valve controlled sealing structure (VRLA), and the internal electrolyte is adsorbed in the glass fiber partition without free liquid. It can be placed in any direction without leakage, and the installation is flexible and convenient. The battery casing is made of high-strength ABS material, which is impact resistant and corrosion-resistant. The top is equipped with a safety valve that can automatically exhaust when the internal air pressure is abnormal, preventing the shell from breaking and ensuring safe use.

Its core advantage lies in its "maintenance free" feature: there is no need to add distilled water or check the electrolyte level throughout the entire service life, greatly reducing operation and maintenance costs and manpower investment. Low self discharge rate, less than 3% per month at room temperature, suitable for long-term float charging backup; Good deep cycle performance, supports multiple charge and discharge cycles, and extends the overall service life. The terminals are made of copper core silver plated or tin plated, with strong conductivity and low contact resistance, ensuring stable and reliable high current output.

Compliant with international certification standards such as CE and UL, the environmentally friendly design includes a Pb recycling label and meets the requirements of the RoHS directive. The working temperature range is wide (-15 ℃ to+45 ℃), suitable for various harsh environments. Typical application scenarios include: UPS power supply for hospital operating rooms, backup power supply for bank ATM machines, factory automation control systems, photovoltaic power plant energy storage units, etc. The target users are power engineering companies, IT equipment integrators, communication operators, and new energy project developers, pursuing cost-effective, stable, durable, and easy to manage DC power solutions.
