Yes I understand, I have a Noco genius 5. What I'm getting at is the battery should not have sulfated because it's always been kept charged to a correct amount (roughly 12.7-12.8 volts). Batteries will sulfate when they get low on charge for a long time period (weeks to months).
If you do a repair mode w/ the NOCO, be sure to remove negative battery cable! Bill P
90% soc is not fully charged. Even 98% is not fully charged. In addition the prevailing fear of over charging even 0.001% can result in a slight sulfation. The continual charging to 98% will result in the original capacity being reduced to 97-96-95% etc. it's more of a number of cycles. Not known how BMS is handling the float charge voltage reduction when it's over what BMS wants? Perhaps a separate voltage regulator just prior to battery under control of BMS would help. I would prefer a separate trickle charge from the HVB be available for the 12v when the HVB is over 40% when the truck is off. If Ford's first qtr 25 fix is not satisfactory I may install a 6ah lithium ion rechargeable battery to power my noco maintainer so I don't have to plug it in as much.
