SiO2 Charging Profile

With FLAs doing successive incomplete recharges in a row leads to Progressive Capacity Loss. We talked about this on here about ten years ago. You must do a "recovery" to Full every so often or your capacity gets so low you can't get through the next night. Depends on the whole scenario how many days you can do it.

Ok but dammage is done every time it is not fully charged, tiny buts of damage but dammage none the less that is not reversable. so even if you do charge to 100% your only preventing the extra bit of damage from that cycle not from the previous times you didnt get to 100%. there are desulfication methoes but they are doubious at best and don't totaly fix things if they fix anything at all.

so by running 50 to 80 or 50 to 90% you are just acepting a shorter battery life kinda like if you run a LFP from 100 to 0 all the time you are acepting your only going to get the advertised cycle life which is Ok as long as you are fine with that. but telling people to not fully charge with out telling them that there may be a slight trade off in cycle liffe or capacity the more they do it is not cool. a lot of new people who only know that a battery makes there lights work read this stuff and go out and buy expensive batteies then wonder why there getting killed in 3 years.

I agree that solar has helped but that again can be an issue of the system is sized to small and your battery reserve is to small. I have mine set up to in normal conditions to only use the top 20% of the battery bank and then once and a while dip a little lower, but my solar can recover my bank from 50% to 100% by 2pm whish is why my last batteries lasted 14 years before showing any indication they were old.

with the new LFP in the camper I only use the top 10% of the capacity as it isn't there to run everything and the solar has it charged full befor noon , but it is rather for the emercency capacity when I am in the bush and the solar isn't working for some reason (snow, rain, etc.)
