I can get 15kwh in quality deep-cycle 6v. lead-acid batteries for something like $2800.00...will these Li-ion batteries outlast properly charged/cared for lead-acid batteries?

A lithium-ion battery should be able to Las 10,000 cycles before having to be replaced. How many cycles can a lead battery go through and, after 10,000 cycles and battery replacements, which is cheaper?
