Marked by a sign + positions concern only the unattended storage battery which is established serially. Take into consideration these instructions. If in addition storage battery demanding more difficult maintenance was established, take into consideration all positions.
Before a charging check electrolit level, if necessary add the distilled water.
Never close накоротко the storage battery. At short circuit it heats up and can burst. Do not shine the battery with an open flame. The electrolit (on the basis of sulfuric acid) is corroding liquid and should not get to eyes, on skin or on clothes, if necessary wash out a large amount of water a place on which the electrolit got.
Disconnect from plugs of the storage battery a positive wire and a weight wire. At accession and a detachment of wires pay attention to that did not arise the sincere. Therefore previously disconnect all consumers of a current.
Before a charging give the chance to settle to the frozen storage battery. The charged battery freezes approximately at temperature–65 ° With, semi-charged – about-30 ° With, and discharged – approximately, at–12 ° Page.
Unscrew jams from the storage battery and put them on openings. It will prevent hit of splashes of electrolit on a varnish, and at the same time at a charging being formed gaseous products can disappear.
Charge the storage battery only in well aired room. At a charging of the built-in battery room of the battery leave open a trunk lid.
At a normal charging the charging current makes 10 % from capacity (at the storage battery in capacity 74 А*ч, therefore, about 7,4 And).
The storage battery can be charged also by means of the fast-charging device.
Connect a positive pole (+) the storage battery to a positive pole of the charger, and a negative pole (–) the accumulator with a negative pole of the same device.
During a charging the temperature of electrolit should not exceed 55°С, in case of need interrupt a charging or reduce a charging current.
Charge until brisk gas evolution in all cells will stop and tension and specific weight of the electrolit, measured three times with an interval in one hour does not increase any more.
After a charging check electrolit level, if necessary add the distilled water. + Check electrolit density. If the measured density in one cell less than other values (for example, in five cells the density makes 1, 26 g/ml, and in one cell – only 1, 18ú/ml), the storage battery is faulty and it is necessary to replace it to (restore).
Leave approximately for 20 minutes the storage battery for complete allocation of gases, then screw up jams.
