Large capacity: the use of patent structure design, mining the most effective use of space within the battery, 2Hr capacity than similar products higher than 5%-10%;
The large current discharge performance: plate grid with transverse stiffened thin, longitudinal reinforcement dense new structure, greatly reducing the ohmic resistance of the battery, large current discharge within the electrochemical cell response uniformity, low voltage drop and deep discharge recovery after good performance;
The grid has good corrosion resistance: the unique patented alloy material makes the grid has super corrosion resistance and creep resistance;
Active material utilization: special additives patent products, and creating a refined cream and curing in four basic lead sulfate particles, improve the utilization of active material, greatly improving the battery output rate;
Little water loss: increase the battery liquid adding quantity, solves the battery water loss late dry battery expansion problem;
Low self discharge rate: using a certain amount of negative additives, with a special technique is added to the negative electrode active material, not only to overcome the self discharging effect, and can reduce energy consumption by 79% in the first charge;
Low temperature performance is good: the plates added active high conductive material and low expansion agent products with super low temperature charge discharge ability, avoid the battery in the winter when the mileage dropped;
Safe and reliable: the battery box the check valves are designed independently, using automatic anti early dry and detachable safety valve, the valve has the common battery check function and fluid sealing function, has a sealed battery one-way exhaust, so that the battery water loss in the process of charge and discharge less, high reaction efficiency seal. The use of existing capacity, non fluid, gas recombination function in the electric bicycle, and once in need of maintenance, can easily remove the safety valve for maintenance;
Long service life: the battery discharge depth DOD80% in the standard state can be carried out 400~600 times cycle, under the standard state, a charge continues mileage 40~60Km.
The scope of application of solar energy battery
"Day" brand of lead-acid battery is widely used in electric vehicles, electric vehicles (golf carts, buses, sanitation vehicles, vehicle, electric forklift), electric ships and electric tools.
After sale service
Thank you for purchasing the products of our company. This product is strictly controlled according to the national quality system standard. Day battery warranty for a year, since the date of purchase within one year the product non-human damage, the company responsible for maintenance.
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.
