WWI. Manufacture of alkaline batteries began in the United Kingdom some time before the end of the war; one of the first manufacturers was Worsnop and Co, which later set up Alklum Electrics.
1922 Pritchetts and Gold acquired some shares in Worsnop and Co and Alklum Electrics, and considered buying its alkaline battery business, principally, it seems, with train-lighting uses in mind. Having tested the various products, Pritchetts and Gold decided that the Jungner (of Sweden) battery was superior.
1923 Not long after it had passed into the control of Chloride Electrical Storage Co Ltd, Pritchetts and Gold made an agreement with Jungner under which it acquired one-third of the capital of Batteries Ltd and agreed to have no other alkaline battery interests. Pritchetts and Gold's interests in Worsnop and Alklum Electrics were sold to Batteries Ltd.
1925 Alklum Electrics was wound up.
1932 Worsnop set up another company — Alklum Storage Batteries — and in the following year went into liquidation.
