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 100% examination, can effectively detect very few doubts electric line when it is hard to detect the
The library is based on open circuit voltage and internal resistance of battery was two times with the group.
