Our Tubular Ultra Low Maintenance Battery is made using the special technology by which the active material is encapsulated in polyester tubes to prevent 'Shedding'. The electrode geometry facilities 'cyclic' deep discharges i.e. long repetitive power outages. They are recommended for back up power for UPS & Inverters where environmental conditions are tough and high ambient temperatures are common. Tubat Tobular proved to be most reliable source of back up power for Inverters and UPS operating under demanding conditions. These are capable of long hours of backup.
