Description
Lead-acid batteries series DTM ASTERION brand are a clear example of sealed maintenance-free batteries with gas recombination system (VRLA), produced by AGM technology (electrolyte absorbed in glass fiber separator). DTM is an universal series recommended to be used both in buffer and cyclic modes. Designed for application in mobile and handheld devices, and due to stable high homogeneity of the internal resistance of products, is ideal for use in back-up power sources and units.
