I'm not sure if it was logged in ForScan- I think I posted a screen print of the SOC in another thread? It was probably charging slowly at a steady float voltage/ low current. My theory is the charger indicates full (via a green LED on my Ctek) to merely tell you the battery is good to go/ will start an engine. Based on a preset time at the float stage perhaps?David out of curiosity did you check what volatge was across the battery at the end of the charge while the charger was still connected?
My battery being over 4yo may also slow the full SOC process down.
