廣州koyosonic蓄電池GFMG-300原裝2V300AH 性能 參數(shù)
Based on 18-year experience in research and development, in 2008, we succeeded in designing NPS batteries mainly suitable for Solar / Wind power or Photovoltaic system and then we call NPS batteries as PV batteries too. In fact, the use of AGM batteries in deep cycle applications is short sighted because the AGM batteries will fail prematurely indeed the AGM battery capacity will start to reduce from the day of installation. With the great help of Doctor Yoshida Masayoshi in Toyama Universityin Japan,we combine gel technologies with deep cycle technologies by putting somespecial elements in lead alloy and some additive in electrolyte to get muchmore longer cycle life for NPS batteries. NPS can be regarded as another type of special gel deep-cycle batteries.
Voltage: 2V, 6V &12V Capacity: 9AH to 3000AH
Service Life: Battery floating service life can target 15 years at 20oC/68oF to 25oC/77oF

Q1: Do you have any certificates?
A: All our batteries are approved by CE, UL, ISO9001, ISO14001, OHAS18001.
Q2: Do you have real factory?
A: Yes, we have AGM-VRLA Batteries factory in Foshan, & Car Batteries factories in Hunan & Guangzhou. We welcome you visit our factories, and we produce batteries plates by ourselves, so we can have good control on cost and quality.
Q3: How's the delivery time?
A: Usually about 25-30 days, urgent orders can be arranged within a week.
Q4: Can you print my picture or logo on the battery cover?
A: Yes, OEM is available,we can print your picture or logo on the battery case, and you can offer your logo.
Q5: Why batteries have different capacity at different hour rate?
A: The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current. For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharge at 100A. With 20Hr-rate, the battery is able to deliver more Ahs than with the 2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.
Q6: How is the Warranty?
A: 25°C, Over 100Ah 3years, Over 50Ah 2 years, below 50Ah 1 years ,Free replacement if defective by factory problem, no need return.
