Good safety performance
Lean liquid electrolyte battery design, are all plates and superfine glass fiber separator without electrolyte adsorption, free flowing inside the battery, no electrolyte leakage under normal use, side installation of 90 degrees can also be normal use.
Control valve type structure, when the battery is in high pressure occasionally through an automatic, open safety valve, release the pressure, ensure the safety of internally generated combustible and explosive gas gathering, reach explosive concentration, excellent explosion-proof performance.
Maintenance free performance
Absorption sealed maintenance free use of the cathode gas sealing composite principle, efficiency is more than 95%, under normal circumstances the use of water is few, the battery without regular maintenance infusion.Green environmental protection
No mist under normal charging, no pollution, no corrosion of equipment room environment.
Self discharge small
The Pb-Ca-Sn alloy with high gassing potential is placed in the dry environment at 20 degrees for half a year, and it can be put into normal use without power supply.
Applicable environment temperature is wide
- 45 DEG C can run smoothly.
High resistance to high current performance
The 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 purity of 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 of the battery group 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;
The library is based on open circuit voltage and internal resistance of battery was two times with the group.
