The rechargeable battery, the generator and starter provide launch of the engine, each of them performs the function and is connected with the others. So, without rechargeable battery it is impossible to include a starter, without starter the engine and the generator will not begin to work. Without generator recharge of the battery is impossible.

TECHNICAL DICTIONARY
Basic concepts
The closed chain is necessary for passing of electric current. It consists of a source (for example, the rechargeable battery), consumers (lamps, a starter) and wires by which are connected a source of current and consumers.
Tension is a potential difference, is measured in volts (In).
Current characterizes the size of the electric charge postponed through the section of the conductor for a unit of time, is measured in amperes (And).
Power — the work of tension and current which shows what electric work the source of current makes in relation to the consumer is measured in watts (W).
Resistance which is shown by an electric chain (conductor) to the electric charges moving in it. This relation of the tension attached to resistance, to current, proceeding on resistance, a unit of measure — Ohm.
Wire. Thickness of a wire (cross-sectional area) depends on the consumer. For a control lamp there is enough section of 0,5 mm2, the wire with a section of 16 mm2 is necessary for a starter. Too thin wire can overheat therefore tension falls. In this case headlights are reached, for example, not by(with) 12 V, but 10 or even 9,5 Century. As a result light of headlights becomes dim.
