Correctly picked up accumulator

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

  • 12 In/36 And hour, 175 And (for the four-cylinder engine with working volume of 1,6 l).
  • 12 In/44 And hour, 220 And (for the four-cylinder engine with working volume of 1,8 l).
  • 12 In/70 And hour, 320 And (engine capacity 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

Tension and capacity: in designation 12 In/44 And / h standing ahead 12 In inform, certainly, on tension of the accumulator. After the slanting line the current in «temporarily delivered quantity» is specified – A means hour 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 a capacity half.

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

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

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