How to Use a Diode to Stop Battery Drainage Diodes are used in electronic circuits to prevent electrical current from flowing in more than one direction. They are also used to push electrical current from one point in the circuit to another, such as is the case in a solar cell charging circuit. When a diode is used as a means to control the direction of current flow, it is referred to as a "blocking" diode. When solar panels are exposed to light, these panels generate electricity and can charge a battery. If a blocking diode is not present, the solar panels can also drain the battery when the solar panels are not exposed to light.

How to Build a Battery Isolator Automotive battery charging circuits are designed to recharge and maintain a single battery. However, automobiles with custom audio systems, electric winches or other high-drain devices may require a second battery to power these devices. One of the problems with connecting two batteries directly to an automotive charging system is that if one battery is weaker (provides less electrical current at the same voltage) than the other, the charging system may be taxed beyond its design parameters for providing power. This also has the undesirable consequence of draining the “good” battery to equalize the charge in both batteries. One way to charge both batteries without overtaxing the charging system is by using a battery isolator. A battery isolator is constructed using two diodes, which act as one-way electrical check valves for the charging system.
