If difficulties with launch of the engine in use appeared, check degree of state of charge of the rechargeable battery on density of electrolyte or tension on its conclusions in not loaded state (tab. 10.6). For check of density of electrolyte use the areometer or the float-operated indicator of density of electrolyte which is available on sale. Tension on conclusions of the battery can be measured by any voltmeter of a direct current with a limit of measurement of 20 V (the similar voltmeter is a part of all autotesters which are available on sale).

If degree of state of charge of the battery of 75% or below, it it is necessary to remove from the car and to load by means of the charger.
