Correctly picked up accumulator

The accumulator in all models Audi A4 is on the right ahead in a so-called humidifying box (between the engine and a windscreen). For engines of different capacity in А4 accumulators of different productivity are provided also:

  • 12 В/36 And hour, 175 And (for the four-cylinder engine with working volume 1,6).
  • 12 В/44 And hour, 220 And (for the four-cylinder engine with working volume 1,8).
  • 12 В/70 And hour, 320 And (working volume of the engine of 1,8 l with an automatic transmission, and also for all six-cylinder engines).
  • It is possible to establish also larger accumulators, than are listed above.

Accumulator data

Pressure and capacity: in a designation 12 В/44 А/ч standing ahead 12 In inform, certainly, on pressure of the accumulator. After a slanting line the current strength in temporarily delivered quantity is specified – A hour means ampere-hours. It is nominal capacity of the accumulator which is measured according to standard conditions. Actually count only on 2/3 specified capacities; but if the accumulator old, only on half of capacity.

Current at low temperatures: number 220 And or 320 And designate a current strength which can give the accumulator at–18 С.

Type number: the five-place number at all German manufacturers of accumulators serves for a designation of accumulators. In Audi also corresponding numerical characteristics. For example, in figures 54 459 or 57 0707 first figure (5) means pressure of the accumulator in 12В. The subsequent figures 44 or 70 inform on accumulator capacity. Last two figures mean design signs, for example, its form, an arrangement of poles, a hose for decontamination, the handle and a fixing lath at the basis.

 Councils: If purchase of the new accumulator it is not necessary to stop on number of the type resulted Audi is necessary. Manufacturers of accumulators conduct comparative lists on which basis it is possible to define the suitable accumulator. For the sake of lower price it is possible to refuse practical handles for accumulator resocks. But for safety on compromises it is impossible to go at accumulator fastening.
