Sealed Lead Acid Batteries

There is a growing trend among users of lead acid batteries towards use of sealed maintenance free designs. These offer the user many advantages in freedom of battery placement, increased safety, battery size and weight, no need to water, and in some instances superior performance. In standby service, two battery types are rivalling the traditional flooded lead acid stationary battery. Both are sealed, contain immobilized electrolyte and are "maintenance-free" by operating in the oxygen cycle. The difference in these sealed cell designs will be discussed together with a comparison of performance characteristics.
