ya thats what mine looked like after almost 16 years, the slots up the sides of the tubes are to prevent what you are talking about, I was taught to always fill it to the very bottom of the tube but to never go higher or cover the slots. this could be wrong but it gave you a consistant way to judge your level and I have been doing it for 40 years now.. well aside from in my camper it is LFP now haha, but the 5th is still CG2
No right or wrong way with water level with the exception of making sure there is always electrolyte ABOVE the plates.
Anything between that and the bottom of the filler tube is fair game.
Extra electrolyte above the plates doesn't add Ahr capacity, it is simply nothing more than a spare "reservoir" of electrolyte. That reservoir of electrolyte also allows for longer periods of time between needing to water the battery. So filling to the bottom of rings maximizes the time between filling.
But a bit less electrolyte than at the bottom of the rings allows extra air space also allows for more expansion/contraction of the electrolyte and can reduce some of the acid/water loss through the caps.
As long as you have a decent multistage converter, you really do not need to fuss over them, I don't, I check levels once per yr and has worked very well for me.
