Good morning. I'm trying to maximize the charge of my agm victronenergy 110 Ah. I made some considerations: Solar charging can never complete 100%. Because time is not enough. Correct solar charging reaches 99%. My battery is exclusively maintained by solar mppt. I stop ABS when the tail current on the smartshuunt drops below 2%, i.e. below 2.2A, for at least 15 minutes. This usually occurs after 1.5 hours / 2.5 hours of ABS. In fact, my previous dod is always 15/20%, no more. My mppt allows a maximum abs time of 3 hours. Or an all day ABS, raising the floating voltage to the ABS value. After 3 hours of ABS, the tail current manages to drop to 1.5A. I have read that many battery manufacturers believe that 100% is reached only after 16/20 hours of charging. When the tail current drops to very small values. Much, much smaller than 2%. Is it better to stop Abs with tail current of 2-2.5%, or wait for tail current of 1-1.4% ?? Do you think it is preferable to keep Abs time for 3 hours every day? ? And once a week even do an abs time all day long? I thought that if my recharge reaches only 99.x% and not 100%, my battery will experience an inevitable and slow sulfation. Because the 0.x% that is not recharged every day will slowly transform the sulphate with irreversible crystals. It's right?
