7.2.6. Charging of the rechargeable battery

The battery removed from the car accurately clear, especially its top part, check the level of electrolyte and if necessary bring it to norm.
The battery is charged with a current of 5,5 And at the turned-out traffic jams. Exercises are done prior to plentiful gas emission and achievement of constancy of tension and density of electrolyte during 3 h. Density of electrolyte of the charged battery at 25 °C has to correspond to these tab. 7.5 for each climatic area.
When charging battery it is necessary to check periodically temperature of electrolyte and not to allow its increase over 40 °C. If temperature reaches 40 °C, then it is necessary to reduce half charging current or to interrupt charging and to cool the battery to 27 °C.
Charging stops when plentiful liberation of gas in all elements of the battery begins, and tension and density of electrolyte during the last three measurements (made in 1 h) will remain constants.
If at the end of charging the electrolyte density (determined taking into account the temperature amendment) differs from specified, then modify it. At the increased density select a part of electrolyte and add the distilled water. If density of electrolyte is lower than norm, then having selected it from an element, add electrolyte of the increased density (1,4 g/cm3).
After adjustment of density of electrolyte continue battery charging within 30 min. for electrolyte hashing. Then switch-off the battery and in 30 min. measure its level in all elements. If the level of electrolyte appears below norm, then add electrolyte with a density corresponding to this climatic area (see tab. 7.5). If the level of electrolyte is higher than norm — select its surplus a rubber pear.
