Overview
What it is and how it fits the system.
The Yuasa NP7-12 is a 12V, 7.0 Ah Valve Regulated Lead-Acid (VRLA) Absorbed Glass Mat (AGM) battery from the NP/NPX Series, built with HT X Alloy high-temperature chemistry for fire protection, life safety and standby applications. Rated at the 20-hr rate (1.75vpc at 25°C) with a 4-6 year design life, it supports float charging at 2.275V/cell and cyclic charging at 2.45V/cell. It operates across a wide discharge temperature range of -20°C to 60°C.
Technical overview
The NP7-12 is a 12V, 7.0 Ah Valve Regulated Lead-Acid (VRLA) Absorbed Glass Mat (AGM) battery from the Yuasa NP/NPX Series with HT X Alloy high-temperature chemistry. Designed for fire protection, life safety and standby applications, it supports float charging at 2.275V/cell and cyclic charging at 2.45V/cell, with temperature corrections of -3mV/°C/cell and -4mV/°C/cell respectively. Rated at the 20-hr rate (1.75vpc at 25°C), it offers a 4-6 year design life and operates across a discharge temperature range of -20°C to 60°C.
Internal resistance is approximately 22.0 mΩ with a maximum charge current of 1.750 A. Compatible variants include NP7-12-250FR, NP7-12-250, NP7-12FR, and NP7-12-TAA, and it supersedes the RB70FR model. Applications span power packs, solar and wind support systems, UPS, emergency lighting, fire protection, life safety, and security systems. Physical connection details are documented in the installation manual.
