Hannibal Power and Technology offers top VRLA batteries for UPS.

Lead acid VRLA batteries have been the most prevalent type of battery utilized for Industrial UPS applications due to the benefits they offer over the more traditional VLA battery type; they are a “sealed” battery in that, in their basic design, utilize a starved electrolyte absorbed in a plate separator or formed into a gel. Oxygen will recombine with hydrogen to form water. The only venting to the atmosphere is a one-way safety pressure relief valve in case the rate of hydrogen evolution becomes too high. Because of the “sealed” nature of the design, the batteries (1) do not lose electrolyte; (2) are leakproof; and (3) can be installed in any position.

All these benefits mean that VRLA batteries require less maintenance than VLA-type batteries. While the maintenance is minimal, it is recommended to perform regularly scheduled maintenance checks and monitor the batteries to verify their condition and help mitigate the risk of thermal runaway. There are two main designs of VRLA batteries:

Absorbent Glass Mat (AMG): Electrolyte is held in glass mats with very thin fibers
Gel Cell: Gelatin electrolyte of sulfuric acid mixed with fumed silica
Out of the different UPS lead acid battery types, VRLA batteries tend to be the most cost-effective solution for the initial upfront investment. They have good performance and work well for most runtime requirements outside of long (hour-plus) situations but do sacrifice lifespan compared to the other lead acid battery types.

VRLA Battery Life

While lead acid VRLA batteries have a design life of 10 years, they realistically need to be replaced every 4-5 years to ensure peak performance.

Battery life can be adversely affected when constantly subjected to a higher ambient temperature than recommended by the manufacturer. Discharge cycles for the batteries also factor into life expectancy, with the rate, length, and frequency of the discharge all playing a role. Lastly, charging attributes influence VRLA battery life; they should be maintained at a float voltage equal to or below the battery manufacturer’s recommendation. Exceeding this preferred value will lead to an overcharge situation and reduce battery life.
