The battery which was not used long time (for example, it was not maintained the car), is discharged and, besides, can сульфатироваться.

Actually the battery is damaged.

Before to define the battery as damaged, it is necessary to check up the following:

  1. Electrolit density. If the difference between density in separate sections does not exceed 0.04 g/ml it is necessary to charge the battery normal зарядным the device.
  2. After gymnastics check up the battery under loading. If characteristics of the battery below resulted in Specifications, the battery is damaged.
  3. If the electrolit density in one or in two next sections considerably differs (for example, in five sections 1.16 of g/ml, and in the sixth 1.08 g/ml) the battery has short circuit and it is necessary to replace it.
