The only problem or something to be aware of is the life expectancy. L-Ion batteries have a shorter lifespan than Lead Acid. They chemically decay and last about 3 yrs max. I just replaced my OEM Lead Acid battery at almost 6yrs of life. (kept on float charger when I'm not riding) So for me the ROI is just not there for me.
L-ion and Lead Acid batteries are best left on charger all the time when not riding. L-Ion do not have a "memory" problem like Ni-cads.
Mine went the same way, slow to start and then no start. Found a slightly larger battery (thicker front to back) that fit in the battery well and offered more amps an XTAX14-BS.
