Product Description Tubular Plate Battery 2V 250AH (OPzS250-2) Specifications The OPzS battery is a traditional tubular plate flooded battery which offers 20 years design life with a cycle life of 1800 cycles at 80% Deep Of Discharge. This range is most suited for all standby power applications that require the highest levels of reliability and security. Characters 1. Use gel electrolyte, with nice performance on wide temperature range, suitable for harsh environments coperation. (-40�º C~60�º C) 2. Made by tubular positive plate materials, monthly self-discharge rateâ?¤ 1.5% 3. Excellent recover ability of Cycling and deep discharge, more than 800 times cycle life at 100% deep discharge, improve the system reliability effectively. 4. Floaing design life time up to 20 years, in the coperation of normal float charging, capacity keeps stable, attenuation rate stays low. Application Wind power system, Solar power system, Emergency lighting alarm systems, UPS(Uninterruptible power sypply) Telecommunications, Telephone exchanges control equipment, EPS instrumentation, Bank ATM System, Medical equipment, Fire and security system and so on.
