Don't wish to nit-pick you bro but shelf life is much different than charge cycles. I've heard lithium shelf life may only be a matter of couple years even if they're never charged/discharged. Sorta like Capacitors in that regard. Dunno 1st hand - just reading here & there like everybody - but something that probably deserves more investigation IMO.
If you only need a small AH capacity (short commute - testing components) are on a budget - lead is still pretty hard to beat IMO.
