Maintenance Free 490Ah 10Hr OPZS Battery Deep Discharge Recovery Performance

These OPZS batteries a traditional tubular plate flooded battery which offers 25 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.

Product Features:
1. Use gel electrolyte, with nice performance on wide temperature range, suitable for harsh environments coperation. (-40º C~60º C)
2. Made by tubular positive plate materials, monthly self-discharge rate≤ 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 25 years, in the coperation of normal float charging, capacity keeps stable, attenuation rate stays low.

Applications:

1. Power plant & Hydropower station
2. Photovoltaic & Solar system
3. Emergency power system
4. Telecommunication
5. Electric utility
6. UPS & BESS

Advantages:

1. The battery is full of power when it's out of factory, no need to use liquid charge; 
2. No memory, no need to discharge battery use, suitable for circuit design; 
3. By high partition, adsorption and strong; 
4. There is no flowing liquid (poor liquid), does not leak acid and free Upside down, 
5. Comply with environmental requirements, ease of use, 
6. The use of lead-calcium alloys, battery self-discharge is very low, 
7. Easy storage, less maintenance; 
8. Using ABS plastic shell and valve technology for safe use.
