Topline has been representing Renata for many years and sits very well with the EM range of low power semiconductors. Renata are known for their very high quality lithium coin cells and so if you want your new product to have a long life then please look at the Renata range. They still manufacture many batteries in Switerland and at one point were manufacturing 1 million a day! Please call Ian if you would like a catalogue or to order some samples or request a quote.
