In: Acta technologica agriculturae, SPU Nitra, Volume 5, Number 4, December 2002, s.100 - 103, ISSN 1335-2555 Abstract: Motor vehicles and automotive machines availability is substantially determined by technical condition of accumulator. Even proper operation and regular maintenance is unable to anticipate gradual decreasing of the accumulator capacity. This is caused especially by irreversible sulfation. Various regeneration procedures are recommended to eliminate the unfavorable effect. Some of them are based on addition of chemicals into the accumulator cells. The paper presents verification of effects of „LongLife“ and “MečtaSuper” chemicals and hydrogen peroxide accumulator regeneration.
