Product Description

Rechargeable Long Gel Ups 12v 20ah 20hr Batteries 12v Backup Battery

Product Overview


Gel 12V 20Ah lead-acid batteries, through improvements in gel electrolytes, significantly outperform traditional lead-acid batteries in safety, environmental adaptability, and lifespan. They are particularly suitable for UPS applications requiring high reliability and maintenance-free operation, such as outdoor communication base stations, medical backup power supplies, and industrial control equipment. Although the initial cost is slightly higher, the long-term comprehensive cost-effectiveness is better.

Core Product Features


  • Nominal voltage: 12V, compatible with most UPS equipment requirements, and can be directly used or connected in series to form higher-voltage systems.
  • Rated capacity: 20Ah (20-hour rate discharge capacity), meaning it can theoretically discharge continuously for 20 hours at a current of 1A, meeting the backup power needs of low-to-medium power devices.
  • Gel electrolyte: Adopts gel-like electrolyte (composed of sulfuric acid solution and silicate composites), which is solid or semi-solid with no free electrolyte, distinguishing it from traditional liquid lead-acid batteries.
  • Valve-regulated sealed design (VRLA): Fully sealed structure with a safety valve to automatically adjust internal pressure, preventing electrolyte leakage and external gas intrusion.
  • Plate design: Usually uses thickened plates or high-density active materials to enhance cycle life and discharge performance.

Core Advantages



1.Higher Safety and Stability

  • The gel electrolyte has no fluidity, completely solving the problem of electrolyte leakage in traditional batteries. It can be installed at any angle (tilted or even inverted, subject to brand instructions), suitable for narrow or irregular spaces.
  • The safety valve design suppresses the escape of hydrogen and oxygen, reducing the risk of explosion and fire, while minimizing acid mist corrosion to equipment.

2.Excellent Environmental Adaptability

  • Outstanding wide-temperature performance: Operates in environments ranging from -20℃ to 60℃. It maintains higher capacity retention at low temperatures and slower self-discharge at high temperatures, making it suitable for scenarios with large temperature differences such as outdoor areas and machine rooms.
  • Vibration and impact resistance: The gel structure wraps and protects the plates, reducing plate shedding or short circuits caused by vibration, extending service life in mobile devices (e.g., vehicle-mounted UPS).

3.Longer Service Life

  • Cycle life: Deep cycle (discharging to 50% capacity) times reach 500-700 cycles, reducing frequent replacement costs.
  • Float charge life: Under long-term UPS float charge conditions, the service life can reach 5-8 years (ordinary batteries are about 3-5 years), as the gel reduces plate sulfation and corrosion rates.

4.Low Self-Discharge and Easy Maintenance

  • Self-discharge rate: Monthly self-discharge rate ≤3% (ordinary batteries are about 5%-8%). Even when idle for a long time (e.g., as backup power), it can maintain power, reducing the hassle of frequent charging.
  • Maintenance-free: No need to add electrolyte or distilled water, reducing manual maintenance costs, suitable for unattended communication base stations, security systems, etc.

5.Stable Discharge Performance

  • Voltage drops more gently during high-rate discharge, providing more stable output for UPS equipment. This ensures normal switching of loads during power outages, avoiding data loss or equipment damage caused by voltage fluctuations.
