Tubular Batteries use a special technology by which the active material is encapsulated in polyester tubes to prevent ‘shedding’. These types of batteries are recommended for back up power for UPS where environmental conditions are tough and high ambient temperature are common.
The new EL & EL+ range are manufactured as per Exide's proprietary Torr Tubular technology using one of the world's most exclusive, advanced and state-of-the-art 'HADI' high pressure spine casting (at 100 bar) machines, which is not commonly available. With our hi-tech R&D Centre at Kolkata, Exide has developed the high corrosion resistant and robust spine technology using the HADI process, which ensures a super fine grain structure, for strength, long life and highest reliability.
● The designed float life of Exide EL+ extends well beyond 5 years and on a average 8-10 years for EL+ Range.
● The cyclic life of EL+ is also very high to the tune of 1200 cycles at 80% depth of discharge.
● The low antimony content of the spines ensures a very low self discharge loss of the order of 1% of the 10 hour rate capacity per week at 25 degrees C.
● The combination of low antimony alloy and ceramic vent plug keeps the water addition requirement very low. A topping up frequency of once in 6-9 months can easily be achieved in normal operating conditions.
