(CN1217584-A)   NOVELTY - A sealed lead-acid storage battery comprises a container (1) for the electrodes comprising a denatured polyphenylene resin containing a flaky humidity-resistant inorganic substance, a resin-bonded container cover (2) with a vent valve (6) ultrasonically welded to the cover and a top lid (8) for covering the vent valve region. The cover and lid are of acrylonitrile-butadiene-styrene resin.    USE - As uninterruptible power supplies for backing up computers, etc.    ADVANTAGE - The impact strength of the resin is maintained over time so that less water is lost from the battery, internal resistance remains low and trickle life is prolonged.
