How to service the battery?
Described in specialized literatureactions, maintenance of the battery, often frighten newcomers of the rally by their scale. In fact, everything is much simpler - experts assure us. It turns out that in order for the battery to work smoothly, you need to regularly recharge it in the winter and provide seasonal maintenance in the fall. So, how to maintain the battery? For work you will need:
- hydrometer (they measure the density of electrolyte)
- distilled water
- voltmeter at 15 V accuracy greater than 0.1 V
- Charger
- ammeter with a limit of 10 A
- thermometer (we will measure the temperature of the electrolyte)
- rheostat (4 Ω resistance and dissipation power - from 80 W)
How to properly use the battery: seasonal maintenance
With its help check the condition of the battery and, if necessary, carry out recovery measures. The most successful time for such diagnostics is spring and autumn.
- We remove the battery and rinse the case from the electrolyte.
- We check the level of electrolyte in the banks. Focus on the value above the plates by 10-15 mm. If necessary, add distilled water.
- We charge the battery completely. After this, we conduct a training cycle: we give a discharge of the battery with a current of 0.1 or 0.05 from the capacitance C, until the voltage at the terminals reaches 10.2 V with a current of 0.1C or 10.5 V (current 0.05C). We measure the temperature of the electrolyte at the beginning and at the end of the discharge, as well as the discharge time.
When charging the battery, use the formula: C = Iptp/(1+0.01(25-tWed))
- Ip Is the discharge current, A;
- t p - hour, discharge time;
- tWed Is the average temperature of the battery during discharge.
If the received capacity is more than25% differs from with battery problems. In this case, pay attention to treatment measures, which are described in the literature. Also check the density of the electrolyte in the cans with a hydrometer. If between banks the difference in density is greater than 0.005 g / cm3, draw an equalizing charge.
Rules for the operation of batteries: battery charge
The procedure is necessary in winter timeauto. The fact is that low temperatures reduce the capacity of the battery, worsen the ability to take charge, and the start of a cold engine requires more energy. Depending on the machine, charging the battery is carried out just in a month, and weekly.
The most convenient way is to useCharging is an automatic charger that self-sustains the required charge mode. In this case, you only have to comply with the operating instructions. But in the event that in the "charging" manual mode adjustment, it is necessary to choose the suitable one. The actions required for this are also described in the instruction manual of the car.
