GP7-12 best rechargeable sealed lead acid sla 12v 7ah battery for ups
Lead Acid Battery | 12V 7AH | 20 Hour Rate | Dimension: 151x65x95x101mm
GP7-12 best rechargeable sealed lead acid sla 12v 7ah battery for ups has been specifically designed for general purpose and standby applications. The 12v 7ah battery offers excellent performance in a wide range of applications including security and fire systems, medical devices, emergency lighting and UPS systems.
The grid structure of the lead acid battery is made from a lead alloy. Pure lead is too soft and would not support itself, so small quantities of other metals are added to get the mechanical strength and improve electrical properties.
Valve regulated 12v 7ah battery is an Absorbent Glass Mat (AGM) technology with a valve regulated design, that can be used in enclosed and indoor environments without leaking or maintenance, providing a superior performance for thousands of models.
