Product introduction

NP series of VRLA batteries are mainly used in alarm systems, emergency lighting systems, electronic instruments, posts and telecommunications, power systems, large UPS and computer standby power supply, fire standby power supply. The nominal voltage of 6V, 12V, the rated capacity of 1.2AH to 250AH, the design of Floating Life: 7-10 (25 C)

application area

Alarm system,Emergency lighting system,Electronic instrument,Posts and telecommunications,Electric power system,Large UPS and computer standby power supplyFire standby power supply

Good safety performance

The liquid electrolyte in the battery is absorbed by the polar plate and superfine glass fiber separator, and there is no free flowing electrolyte in the battery. Under normal use, there is no electrolyte leakage, and the 90 degree installation can also be used normally.
Valve control sealed structure, when the pressure in the battery occasionally high, can automatically open through the safety valve, release pressure, to ensure safety, the internal combustion of flammable gas accumulation is less, can not reach the explosion concentration, excellent explosion proof performance.




 

Maintenance free performance
The sealing efficiency of the gas seal is more than 95%. Under normal use, the water loss is very little, and the battery does not need regular fluid maintenance.

 

Green environmental protection
> normal charging without acid mist, no pollution and no corrosion of equipment room environment.




 

Self discharge small
The Pb-Ca-Sn alloy with high gassing potential is put into the dry environment at 20 degrees for half a year and can be put into normal use without power supply.




 

Applicable environment temperature is wide
>10 to 45 DEG C can run smoothly.




 

High resistance to high current performance
> tight assembly process, the resistance is small, the discharge current discharge can be 3 times the volume of 3 minutes (7 minutes or more than 24Ah to allow continuous discharge to discharge current and discharge termination voltage) or 6 times the capacity of the battery for 5 seconds, without exception.




 

Long service life
> due to the high pure raw materials and long life formula, battery consistency control technology, NP series battery normal float design life of up to 7 to 10 years (more than 38Ah).




 

Good consistency of battery pack
"Regardless of the cost to ensure the batteries in each cell has the characteristics of relatively consistent, that is put into use after long-term discharge consistency and float consistency, not the individual behind the battery and the battery down.
(1) control the weight and thickness of the grid and the paste quantity from the source;
The general assembly before the plates by weighing and grading (= 38Ah battery), to ensure the consistency of active substances in each monomer amount;
(3) quantitative acid injection, four charging and three discharging formation system, equalization of battery performance;
Before discharging, the battery is discharged, and the capacity and open circuit voltage are matched once;
The static phase detection over 38Ah battery before departure, after 7 to 15 days of the "test of time", the library again seized 100%, very few can effectively detect line to doubt battery detection;
