Ford Focus>> Electric equipment>> Storage battery



Six consistently switched on accumulators form the storage battery (12 In). One accumulator consists of the block of positive and negative plates which together create 12 V.Plastiny's tension consist of lead lattices which are filled with active electrolit. Positive plates are made of a lead oxide, and negative — from pure lead. Between them the separator is established. It divides plates, preventing short circuit, but the electrolit can pass through its minute pores. The electrolit is current-carrying liquid which approximately for 30 % consists of the acid concentrated by a chamois and for 63 % from the distilled water.
In the battery pass the chemical processes connected with power consumption and accumulation of energy. The main objective of the battery is providing a starter at engine start-up in necessary capacity. Depending on the engine and starter type for a short time it can spend to 2000 W.
