2V 350ah Tubular Solar Batteries for Solar

2v 350ah tubular solar batteries for solar 
OPZV350-2

Opzv Series Valve Regulated Lead Acid batteries are designed with a proven combination of GEL and Tubular technologies to offer a very  high level of reliability. Opzv batteries benefit from an optimized plate design which gives capacities in excess of the DIN standard values. In addition, this series offers both a longest float life and a high cycle life in widely industrial field.


Safety and Sealed
No electrolyte leakage will occur from terminals or case or case of any Storace Battery ensuring safe and efficient operation.
 
Maintenance-Free operation
There is no need to add water thanks to unique gas recombination system which totally transforms the generated gas into water.
 
Storace batteries do not need the equalizing charge
As a result of monomer battery's interface resistance capacity and float voltage uniformity are fine.
 
No Free Acid
The special electrolyte retentive separators bold the acid and thus there is no free acid inside the battery, and therefore the battery can be mounted in any position.
 
Long life Design
The use of heavy -duty lead-calcium alloy grids with anti-corrosive construction enables the Storace AGM battery to remain in float service for 10-15 years; the GEL battery to remain in float service for 15-20 years. The cycle life can be more than 1000 cycles
 
High Reliability and stable quality
With advancing AGM and GEL production technology and strictly quality control system, the battery quality is stable and the battery performance is reliable. The voltage, capacity and seal are 100% tested on line.
 
Self-discharge
The self-discharge rate in room temperature is approximately 2% of nominal Capacity per month.
 
Operating temperature
TheStorace Battery can be operated between -40°C to +65°C.The battery can give out over40% fo nominal capacity at -40°C.
