Description
ASTERION HR-W series batteries are sealed, maintenance-free lead-acid batteries with gas recombination system (VRLA), manufactured using AGM technology (electrolyte absorbed in a separator). The HR-W series relates to the ASTERION UPS series, designed specifically for use in uninterruptible power supplies for server and other similar systems. The HR-W series has high energy efficiency due to its use in the production of more massive plates.
