7 FAQ Q: How do I choose the charging current? A: The optimal charging current is up to the battery capacity. We recom- mend that the current be no greater than 20% of the battery capacity. For example, for a 100Ah battery, the charging current should not be greater than 20A. Q: Will T120A automatically stop charging a battery after it is fully charged? A: Yes. T120A follows a smart stepwise charging algorithm. When the battery is fully charged, T120A will automatically stop charging it. There is no risk of overcharging.
If you still keep the battery connected after it is fully charged, the charger will continuously monitor its status and will automatically resume charging when the battery voltage falls below the threshold. Q: How come some batteries cannot get charged properly? A: In general, a 12V battery with a voltage below 8.5V may have been damaged and thus cannot get charged properly. You can try the SUPPLY mode for charging the battery. EN | 009 EN | 016
