They don't lose their charge over extended storage, but this can be mitigated with a battery minder. If lithium were the same price as lead acid it would be a no-brainer. But right now, the advantages are minimal IMHO.

Lithium Iron Phosphate (LiFePO4) vs Lead Acid Batteries - Grepow Blog
Given cost justification within reason my vote goes with safety and less harm to the environment.
Compared to lead-acid batteries, the advantages of lithium iron phosphate battery packs are a lot more. In general, it has the following advantages: small size, lightweight, high energy density, long life, safe use, fast charging with high current, high and low-temperature resistance, large depth of discharge, environmental protection, and no memory effect.
