+ 14.2. Electroschemes Gymnastics of the storage battery

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 service take into consideration all positions has been established.

Before gymnastics check up 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 a corroding liquid and should not get to eyes, on a skin or on clothes, If necessary wash out a considerable quantity of water a place on which the electrolit has got.

Disconnect from plugs of the storage battery a positive wire and a weight wire. At joining and a detachment of wires pay attention to that has not arisen искрение. Therefore preliminary disconnect all consumers of a current.

Before gymnastics give the chance to settle to the frozen storage battery. The charged battery freezes approximately at temperature–65 With, semicharged – nearby–30 With, and discharged – approximately, at–12 With.

Unscrew stoppers from the storage battery and put them on apertures. It will prevent hit of splashes of electrolit on a varnish, and at the same time at gymnastics formed gaseous products can disappear.

Charge the storage battery only in well aired premise. At gymnastics of the built in accumulator room of the battery leave opened a luggage carrier cover.

At normal gymnastics зарядный the current makes 10 % from capacity (at the storage battery in capacity 74 А*ч, hence, nearby 7,4).

The storage battery can be charged also with the help быстрозаряжающего devices.

The prevention

The fast gymnastics of the storage battery should not become a habit! It is not necessary ускоренно to charge storage batteries new or not used long time.

Connect a positive pole (+) the storage battery to a positive pole зарядного devices, and a negative pole (–) the accumulator with a negative pole of the same device.

During gymnastics the electrolit temperature should not exceed 55С, in case of need interrupt gymnastics or reduce зарядный a current.

Charge until brisk gas evolution in all cells will stop and pressure and the relative density of electrolit measured three times with an interval at one o'clock does not increase any more.

After gymnastics check up electrolit level, if necessary add the distilled water. + check up 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,) the storage battery is faulty also it it is necessary to replace 18g/ml to (restore).

Leave approximately for 20 minutes the storage battery for full allocation of gases, then screw up stoppers.

The prevention

The engine should not work at the disconnected storage battery, – the electric system is damaged.
