Advantages of VRLA Batteries

May 29, 2023

Lead-acid batteries have several advantages, making them a preferred choice in various applications. VRLA (Valve Regulated Lead-Acid) batteries, in particular, offer some significant benefits.

Here are the advantages of VRLA batteries:

  • Maintenance-Free: Throughout the battery's entire service life, there is no need to add water or adjust the acid specific gravity. They are designed to be "maintenance-free," saving you time and effort.
  • Leak-Free and Non-Corrosive: VRLA batteries do not leak acid or produce acid mist, which makes them safe to handle. This characteristic ensures that the equipment they power remains free from corrosion, enhancing overall reliability.
  • Low Self-Discharge: VRLA batteries have a small self-discharge rate, meaning they can hold their charge for extended periods. At 25°C, the self-discharge rate is less than 2% per month, reducing the need for frequent recharging.
  • Long Service Life: These batteries boast a long service life, capable of lasting 10-15 years under a floating charge state at 25°C. This extended lifespan provides cost-effectiveness and reduces the need for frequent replacements.
  • Compact and Flexible Placement: VRLA batteries have a compact structure, allowing for convenient placement options such as vertical or horizontal positioning. They occupy a small footprint, making them suitable for various installation settings.
  • Excellent Temperature Performance: VRLA batteries perform well under extreme temperature conditions. They can operate within a wide temperature range from -40°C to +50°C, making them suitable for various environments.
  • No "Memory Effect": These batteries do not suffer from the "memory effect," which refers to the capacity loss experienced during shallow cycle work. This ensures consistent and reliable performance over time.
  • High Specific Energy and Discharge Performance: VRLA batteries offer high specific energy, meaning they can store a significant amount of energy relative to their weight. They also exhibit good high current discharge performance.making them suitable for applications that demand high power output.

In summary, VRLA batteries are a reliable and efficient power storage solution with their maintenance-free operation, leak-free design, long service life, and excellent temperature performance. These advantages make them ideal for a wide range of applications, including communication equipment, uninterruptible power supply (UPS) systems, and other critical power backup needs.
