AC RIPPLE CHARGER 0.5% RMS or 1.5% of float charge voltage recommended for best results. Max. allowed = 4% pk to pk
the amount of ripple allowed in the charger voltage
no more 207 MV ripple recommended, 552 MV peak change, this is the 60hz ripple measured using the AC scale/setting on your digital meter
http://www.alpha.com/Products/Alphaiui/Cable-Broadband/Outside-Plant-Power/Batteries/AlphaCell-GXL/what converter do you have ? in your RV, does it have a gel battery setting ?
gel batteries do NOT tolerate over voltage or over charging
the specs mention float voltage, they do NOT mention charging voltage or charge rates
I would not buy new gel batteries, i would buy AGM
i would buy gel Only IF i found them on the surplus market at a great price, my converter does have a Gel battery setting
