Lifeline's cycle life chart is posted online in the Concorde AGM Manual. Gelled electrolyte batteries have FEW superior qualities over flooded 100% Pb sealed batteries. Specialty batteries for emergency exit lighting exceed cost benefit ratio with almost no superior qualities and nagging lifespan issues. The most vigorous promoters seem to be companies with the biggest investments into gelled manufacturing. The company with the greatest experience with gelled was Sonnenschein. Clearly superior lifespan but they surrendered at once to absorbed glass mat.
