Check of the storage battery

Check of level of electrolit

Electrolit level should be in separate sections between MIN (1) and MAX (2) marks. If level is lower, remove jams (3) and add the distilled water.

Tension check

Tension characterizes a condition of the storage battery and is measured by the voltmeter between separate poles of the battery.


1. Disconnect the storage battery, address to the Section Removal and installation of the storage battery.

2. Before check the battery should be not less than 2 hours disconnected.

3. Attach the voltmeter to poles of the storage battery and measure tension. Address to an accompanying illustration.
If tension makes: 12.7 In or above - the battery in a good condition
12.5 In - the battery in a normal state
12.3 In or below - the battery in bad condition, is necessary a charging or replacement

4. Attach the battery, address to the Section Removal and installation of the storage battery.

Check of the storage battery under loading


1. Attach to battery poles the voltmeter.
2. Start the engine and check tension.
3. At the moment of engine start at completely charged batteries tension should not fall below 10 In (at electrolit temperature near +20°С).
4. If tension sharply falls and the electrolit density in various sections is various, the battery is damaged and it is necessary to replace it.

Check of density of electrolit
(does not treat the unattended storage battery)

Electrolit density together with tension provide guidance on a condition of a zaryazhennost of the battery.


1. Remove jams from the battery.

2. For check of density of electrolit serves денсиметр. The electrolit density is higher, the float денсиметра above emerges. On a scale денсиметра it is possible to establish electrolit density in g/ml or degrees to Boma (+ °Ве). Characteristics of a charge of the storage battery are provided in Specifications.
