Abstract :
Flooded and VRLA cells should be considered as battery types which complement each other. VRLA cells are here to stay because of their gas-free nature, low maintenance, and high energy density. They should not be considered indiscriminately as substitutes for flooded cells. The special sensitivities of VRLA should be taken care of in a system approach. In particular the system float voltage should be reviewed, and adjusted for significant temperature excursions. A system reliability should include continuous monitoring of module voltage, current and temperature, and action steps and safeguards built-in to avoid thermal problems
