Design life 12V series 16 years and 2V series 20 years @20°C in continuous float operation down to approx 80% capacity.
Excellent recovery performance
Wide working temperature range (-20~55)℃
No electrolyte stratification provides longer service life
High recombination efficient
Build in copper core based in lead will carry large current
Separator imported form AMER-SIL high porosity. PVC-SiO2 and low resistance
Pasted negative plate special grid design increase the active material.availablity large current discharge and charge ability
Tubuler type positive plate (polyester tube) prevent the active material from falling. Muti metal alloy pressed positive grid increase the anti corrosion ablity and service life

Self Discharge Characteristics
No supplementary charge required(Carry out supplementary charge before use if 100% capacity is required.
Supplementary charge required before use.Optional charging way as below:
1. Charged for above 3 days at limted current 0.1CA and constant volatge 2.25V/cell.
2. Charged for above 20hours at limted current 01CA and constant volatge 2.45V/cell.
3.Charged for 8~10hours at limted current 0.05CA.
Supplementary charge may often fail to recover the capacity. The battery should never be left standing till this is reached.
Floating voltage: 2.23V~2.25V at 20°C(68°F)Temp.
Boost charge: 2.30V~2.40V at 20°C (68°F) Temp.
Charging current(max.): 0.1CA
Temp.Coefficient 0 -3mV/°C
Capacity affected by Temperature
40°C (104°F) 103%
25°C (77°F) 100%
0°C (32°F) 86%
Self Discharge
Leoch OPzS batteries may be stored for up to 6 months at 20°C (68°F) and then a freshening charge is required. For higher temperatures the time interval will be shorter.
