M2AL12-38SFR 12V38Ah valve regulated sealed lead-acid battery UPS power supply DC screen dedicated

Description :

M2AL12-38SFR is a high-performance 12V 38Ah valve regulated sealed lead-acid battery (VRLA) designed specifically for devices that require stable and reliable backup power. This product adopts advanced AGM (Absorbent Glass Mat) separator technology, and the electrolyte is adsorbed in the glass fiber separator, achieving true maintenance free and leak proof characteristics. It can be safely installed at any angle, greatly improving the flexibility and safety of use.

The core advantage of this battery lies in its excellent cycle life and deep discharge recovery capability. In the floating charging state, its design life can reach more than 10 years, effectively reducing the long-term replacement cost and maintenance burden for users. Its internal resistance is extremely small, and its self discharge rate is low. The monthly self discharge rate is less than 3% in a 25 ℃ environment, ensuring that it can maintain sufficient power even after a long standby period and respond to sudden power outages at any time.

Typical application scenarios include uninterruptible power supply (UPS) systems, emergency lighting systems, communication base stations, data centers, DC screens and operating power supplies for power systems, as well as renewable energy storage systems such as solar and wind energy. In addition, it is widely used in fields such as alarm systems, fire protection systems, and medical equipment that require extremely high power stability.

In terms of installation and maintenance, the product label clearly states that the terminal tightening torque is 110 in lbs (12.4NM), and it is recommended to conduct annual re inspection to ensure the reliability of the connection and prevent heating or performance degradation caused by poor contact. At the same time, the maximum current when using the connector is 4A per square millimeter, providing clear electrical safety guidance for users. The gray ABS shell is not only aesthetically pleasing, but also has good corrosion resistance and flame retardancy, meeting relevant safety standards. Comes with connectors for quick deployment by users. For engineers and end-users seeking cost-effective, long-lasting, and highly reliable backup power solutions, M2AL12-38SFR is an ideal choice.
