EAST batteryCharacteristicGood safety performance

"Lean liquid" design, the electrolyte inside the battery is all poles and superfine glass fiber separator adsorption, the battery without free flow of electrolyte, under normal use without electrolyte leakage, side inverted 90 degree installation can also be used normally.
The valve controlled sealing structure, when the gas pressure in the battery is occasionally high, can be automatically opened through the safety valve, release the 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
With the principle of free maintenance of the cathode absorption type seal, the compound efficiency of the gas seal is more than 95%, the water loss is very little under normal use, and the battery does not need regular fluid maintenance.
Green environmental protection
"No mist under normal charging, no pollution, no corrosion of equipment room environment.
Self discharge small
Pb-Ca-Sn alloy with high gas evolution potential was put into 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
Tight assembly process, the resistance is small, 3 times discharge capacity can be discharged 3 minutes24AhThe discharge current can be discharged more than 7 minutes until the end voltage is stopped or the discharge discharge of 6 times capacity can be discharged for 5 seconds, and the battery has no abnormality.
Long service life
"Because of 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 ~ 10 (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;
(2) weighing and grading of plates before assembly38AhA battery) to ensure the relative consistency of the amount of active substance in each monomer;
(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;
38AhThe stationary period of the battery before storage was tested for 7~15 daysTime trialWhen 100% check out, it can effectively detect the suspicious batteries which are difficult to detect when the line is out of order;
The library is based on open circuit voltage and internal resistance of battery was two times with the group.
