Secondary batteries are recharged by passing a current through the battery in the opposite direction. In a car battery, this occurs when the engine is running. Other examples include the nickel-iron alkaline battery, nickel-zinc battery, nickel-cadmium alkaline battery, silver-zinc battery, and silver-cadmium battery.

About Photovoltaic Energy StorageEffects of Series Connections on Voltage When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts.
About Photovoltaic Energy StorageLet''s say we have three 1V batteries and we''re connecting them to a 1Ω resistor. Connected in series, the voltage is 3V and since the resistance is 1Ω, that means that from Ohm''s law, the current s...

About Photovoltaic Energy StorageTo absolutely maximize solenoid current without regard for battery life, set ratio of battery time to "shorting time" so that the battery is drawn down to about 4.5 volts. That will draw maximum power out of the battery, even though it will cause the battery to waste about half of its energy heating itself.

About Photovoltaic Energy StorageThe unit of measurement for amperage is the ampere, which is often shortened to amp. One ampere is defined as the flow of one coulomb of charge per second. Amperage is not the same as voltage, which is the measure of the electric potential difference between two points in a circuit.
