GP4.5-12 valve regulated 12v 4.5 ah battery for alarm security system

Lead Acid Battery | 12V 4.5AH | 20 Hour Rate | Dimension: 90x70x101x107mm

SKU: GP4.5-12 Category:

GP4.5-12 valve regulated 12v 4.5 ah battery for alarm security system uses a state of the art, heavy-duty, calcium-alloy grid that provides exceptional performance and service life in both float and cyclic applications.

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 4.5 ah 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.
