Number of cycles

NPS Series

Main Features:

Main applications:

Charging method:

Endurance in cycles according to IEC 896-2:

Based on 18-year experience in research and development, we succeeded in developing NPS series batteries mainly suitablefor Solar / Wind power. NPS series batteries are manufactured using Gel technology which is suitable for solar deep cycle applications.

Reduce cell failure due to premature dry out.Extend cycle service life by reducing plate corrosionGelled Thixotropic electrolyteMeet EUROBAT ( draft IEC 896-2 ), IEEE, JIS and Bs6290 Part 4, using UL certified components8-10 year service life for 6 / 12 V NPS batteries and 15 -year service life for 2V NPS batteries 8mm Screw Terminals

Solar Photovoltaic | Solar | | Wind power systems .Alternative Energy Storage

It is recommended to use Constant Voltage method to charge NPS batteries. The charging voltage must beregularly checked. In order to optimize the battery performance, the voltage must be kept within the following limits -

Float Service: 2.25 +- 1% V Per Cell at 20/25°C Cycle Service: 2.35+- 1%V Per Cell at 20/25°C
