FIELD: chemistry.

SUBSTANCE: invention can be used in production of lead accumulators. A flux contains components in the following ratio, wt %: monoethanolamine 1.0-6.0; 40% hydrobromic acid 10.0-20.0; isobutyl alcohol 20.0-30.0; isopropyl alcohol 40.0-60.0; orthophosphoric acid 1.0-5.0.

EFFECT: flux possesses low corrosive activity with good fluxing ability and high rate of drying of an "eyelet" of the bearing current lead of the accumulator plate due to optimal content of acids and alcohols in it.
