Description
Maintenance-free front-terminal lead-acid batteries ASTERION FT-M series are manufactured using AGM technology with absorbed electrolyte. Using this technology, the batteries do not require topping up the distillate during the entire service life. The case design is optimized for installation in 19 "and 23" telecommunication cabinets and racks. The frontal arrangement of the terminals provides ease of installation and routine maintenance during operation. ASTERION FT-M series batteries are optimally suited for power supply systems of mobile operators base stations and other telecommunication infrastructure facilities.
