Reduction of dry-cell batteries in operation 2110

2015-12-06 21:09:05

On the cars coming out from the factory installed batteries ready for action, t. E. Drenched with electrolyte and charged.

The spare parts can come without a battery electrolyte in the dry-charged performance. To

Bring a battery in working condition, it is necessary to remove the existing technological cork or sealing tape. Then, a small stream, through a funnel or a glass of acid resistant plastic pour into the battery electrolyte density reduced to 25 ° C 1.28 g/cm3 for areas with a temperate climate or 1.23 g/cm3 for the tropics. Operations to bring the battery into operation must be carried out at ambient temperature 2510 ° C.

Allow the battery for 20 minutes, the plates and separators impregnated with electrolyte. Next, check the battery voltage without load.

If the battery voltage is not less than 12.5 volts, then it is ready for use. When the voltage is less than 12.5, but more than 10.5 volts, the battery should be-charged to the voltage specified by the manufacturer. When a voltage of less than or equal to 10.5 V battery is rejected.

As a result of impregnation of the plates and separators in the battery electrolyte level is inevitably reduced. Therefore, before installing the battery in the car, it is necessary to bring the level back to normal, pouring an electrolyte of the same density as in the beginning of the casting.

Charge the battery after filling the electrolyte to be necessary if:

- the initial operation of the battery will take place in difficult conditions: in cold weather, with frequent starts the engine, and so on. D.; `

- the battery is stored for longer than 12 months from the date of issue.

Check the level of electrolyte

The electrolyte level in all the battery cells must be between the lines with labels "MIN" and "MAX" marked on the translucent casing of the battery. Do not operate the battery with the electrolyte level below the line with the label "MIN".

If labels "MIN" and "MAX" on the body of the battery is not present, the electrolyte level should be 10-15 mm above the top of the separator.

When using the battery electrolyte level is gradually reduced as the water evaporates, part of its structure. To restore electrolyte level top up with distilled water only.

If it is well established that the cause of the low level is splashing, then top up the electrolyte of the same density as that remaining in the battery cell.

♦ If the level is higher than normal, then aspirate the electrolyte rubber bulb with hard rubber tip.

Check razryazhenposti degree battery.

When battery failure in service, as well as its maintenance is necessary to check the flat battery electrolyte density meter battery hydrometer. At the same time it is necessary to measure the temperature and the electrolyte to allow the temperature correction for hydrometer readings indicated in the table. 7-3.

. If electrolyte temperature above 30 ° C correction value is added to the actual reading of the hydrometer. If the temperature of the electrolyte below

20 ° C, the correction value is subtracted, respectively. When the temperature of the electrolyte in the range 20 to 30 ° C, temperature correction is not introduced.

After determining the density of the electrolyte in each battery cell, it sets the degree of its unloaded ™ on Table 7-4. Battery discharged more, what is 25% in winter and more than 50% in the summer, remove from the car and recharge.

During the measurement of density, take care that the surface of the battery box and other details with the pipette from falling drops of electrolyte containing sulfuric acid, which causes corrosion, leakage and so on. D.

To get the wrong results, Do not measure the density of the electrolyte:

- if the level is not correct;

- If the battery is too hot OR rSOLOD- Ny; optimum temperature in the density measurement 15-27 ° C;

- after topping up with distilled water. Should wait until the electrolyte Mix; If the battery is low, then this may require even a few hours;

- after a few inclusions starter. We have to wait to establish a uniform density of the electrolyte in the battery cell;

- at the "boiling" the electrolyte. Should wait until the bubbles in the electrolyte, scored in the pipette hydrometer, rise to the surface.
