The reducing of antimony in lead-acid batteries in the last 10 years to optimize the maintenance of the batteries on the other hand was to the detriment of the cycle life. In contrast to antimonyfree batteries in conventional construction the immobilization of the electrolyte by gelatinizing permits the production of sealed batteries with highly improved cycle life, high charge acceptance and deep dischargeability. Moreover those batteries do not have a problem of electrolyte stratification. During charging the O/sub 2/-recombination is approximately 75% depending upon the battery size. Because of the O/sub 2/-recombination in this system a wider range of charging potentials of single cells in the battery takes place, which is characteristic of this system.
