Jun 3, 2025 · One of the most significant disadvantages of lithium-ion batteries is their high initial cost. When compared to lead acid batteries, the upfront investment for lithium-ion technology
Improvements to lead battery technology have increased cycle life both in deep and shallow cycle applications. Li-ion and other battery types used for energy storage will be discussed to show
Although alternative energy storage technologies such as fuel cells, flywheels, lithium ion, and nickel cadmium batteries are being explored (see White Paper 65, Comparing Data Center Batteries, Flywheels, and Ultracapacitors for more details) data center and network room UPS systems almost exclu-sively utilize lead-acid batteries.
Vented (flooded or wet cell) batteries have a very long life but present significant complexity of installation and maintenance, the most significant being the need to build a separate battery room. These limitations have historically restricted the application of vented cells to very high power installations.
Characteristics of the vented battery include the following: VRLA batteries have been utilized for approximately 20 years. This technology offers a higher power density and lower capital costs than traditional vented cell solutions. VRLA batteries are typically deployed within power systems rated below 500 kVA.
Ironically, a common cause of electrolyte loss on vented batteries is dripped liquid during specific gravity inspections, as part of routine maintenance. The primary hazard is that areas wet with battery leakage constitute conductive paths to ground that can pose a very serious risk of ground fault.
The primary hazard is that areas wet with battery leakage constitute conductive paths to ground that can pose a very serious risk of ground fault. The biggest concern for vented batteries is that the battery could somehow tip and spill its liquid contents during maintenance or natural disaster.
Parallel string designs, ventilation, overcharge protection, temperature compensated charging, and battery monitoring are the principal techniques utilized to eliminate battery failure hazards. Stephen McCluer is a Senior Manager for external codes and standards at Schneider Electric.
