Check by means of a hydrometer

Direct method of check of the battery on a charge condition – the test by means of a high discharge which is carried out by means of the special exact voltmeter and expensive tool used in repair shops, but not recommended for car owners.

At battery 20 temperature ° C (electrolit temperature):

  • The battery is completely charged, if specific weight of electrolit makes 1.280.
  • The battery is charged half if specific weight of electrolit makes 1.220.
  • The battery is almost discharged, if specific weight of electrolit makes 1.150, and the electrolit is under the threat of freezing.

As specific weight of electrolit changes under the influence of temperature if the temperature indicator does not correspond 20 ° to C (68°F), it is necessary to correct indicators of specific weight (measured by means of a hydrometer) to 20 ° C (68°F) and to apply the received value of specific weight to the three-point specified value.

The method of adjustment can be seen in graphics which shows the attitude of specific weight and temperature.

How to use the schedule of temperature correction of degree of a charge

Let's say the indicator of specific weight of electrolit makes 1.28, and battery temperature — - 5 ° C (23°F). Choose on the Temperature axis value - 5 ° C, and on an axis «Specific weight» - 1.28. Values will be crossed in the zone "And" (the shaded site on graphics). It means that the battery is charged.

To learn a condition of a charge of the battery, will draw direct, parallel lines of differentiation of zones, and continue it to the right until it will not be crossed with a scale of percent. In this case, the line is crossed approximately in a point of 85 % with a scale of percent. Therefore, the battery is charged for 85 %.
