Keep Charged
By using diodes or Field-Effect Transistors (FETs) to only allow current to flow in one direction, a fully charged battery cannot pass current to a partially charged battery. For instance, most battery chargers have isolators. This is how a battery charger can recharge two or three battery banks simultaneously.
