From another hobby where we use lots of batteries of different chemistries (NiCD, NIMH, LIon, LiPoly, LiFE, Gel, AGM, Flooded... some over evolution - some for different uses...) - the gel cell types want a CVC - Constant Voltage Charger... different than what a wet or AGM battery wants where the voltage varies based on the phase of charge. (There is a reason for the different settings on better external chargers - not aware of a converter with a setting like that - I assume they make one that will handle gel? but haven't looked.)
Even AGM and traditional flooded have different needs - but they are a bit more compatible than the gel requirements.
Can seriously shorten the life of a gel battery it it isn't kept happy... which is why DW's 'scooter' with its 36v gel setup has its own dedicated charger...
