Yuasa NP12-12 12V 12Ah Sealed Lead Acid Battery

Description

Overview

Yuasa NP12-12 is a 12V, 12Ah valve-regulated lead-acid (VRLA) battery from Yuasa’s widely specified NP standby and cyclic series, designed as a maintenance-free, spill-proof power source for uninterruptible power supplies, fire and security control panels, and industrial backup applications. Built with absorbed glass mat (AGM) construction and a sealed, valve-regulated design, the NP12-12 requires no electrolyte top-up and can be mounted in any orientation within an equipment cabinet, making it a standard replacement battery specified by UPS OEMs and panel integrators worldwide.

As the official authorized partner and exclusive regional representative for Yuasa, Seven Star LLC proudly supplies the NP12-12 across Oman and the wider GCC, giving facility managers, UPS maintenance contractors, and control panel integrators in the Sultanate of Oman genuine, factory-fresh Yuasa batteries with reliable float-charge performance for critical standby power applications.

Operating Principle

The Yuasa NP12-12 stores and delivers electrical energy through a reversible lead-acid electrochemical reaction contained within a sealed, valve-regulated enclosure. Unlike flooded lead-acid designs, the electrolyte is fully absorbed into glass-mat separators, so oxygen generated at the positive plate during charging recombines internally with hydrogen at the negative plate rather than venting as gas, keeping the battery maintenance-free and safe for mounting inside enclosed equipment cabinets without external ventilation.

A pressure-relief safety valve opens only under abnormal overcharge conditions to prevent case rupture, while under normal float-charge operation at 13.65V (±1% at 20°C) the battery remains continuously topped up and ready to deliver rated capacity the instant mains power is interrupted. This design gives the NP12-12 a low self-discharge rate suitable for extended storage of up to twelve months, along with predictable performance across both standby float duty in UPS strings and cyclic duty in control panels and emergency lighting systems.

Engineering Design of the Yuasa NP12-12

The Yuasa NP12-12 is housed in a flame-retardant ABS case measuring approximately 151mm x 98mm x 97.5mm and weighing approximately 4 kg, sized to fit standard UPS battery compartments and 19-inch rack-mount battery trays used throughout the industry. Termination is via 0.250-inch (6.35mm) Faston quick-connect tabs, allowing rapid field replacement without soldering, and an integrated carrying handle simplifies installation and swap-out in tall equipment racks or overhead panel mountings.

Internally, the Yuasa NP12-12 uses low-antimony or calcium-alloy grid plates optimized for minimal water loss and extended design life of 3 to 5 years in float service, and the AGM separator construction provides strong resistance to vibration, making the NP12-12 suitable not only for stationary UPS installations but also for mobile and cyclic industrial equipment. The sealed case construction permits safe operation across an ambient temperature range of -20°C to 60°C, covering both air-conditioned server rooms and warmer, less-controlled plant equipment rooms typical of Gulf industrial sites.

Key Features

The Yuasa NP12-12 battery combines proven VRLA construction with practical features that support long, reliable standby service:

  • Delivers 12V, 12Ah nominal capacity in a valve-regulated, sealed lead-acid (VRLA/AGM) construction requiring zero maintenance.
  • Spill-proof, any-orientation mounting is possible thanks to fully absorbed glass-mat electrolyte and internal oxygen recombination.
  • Supports both float (standby) charging at 13.65V and cyclic/boost charging at 14.5V (±3%) for flexible application duty.
  • Low self-discharge rate allows storage for up to twelve months at normal ambient temperature before requiring a top-up charge.
  • Flame-retardant ABS case with integrated safety pressure-relief valve protects against overcharge-related case rupture.
  • 0.250-inch Faston quick-connect terminals enable fast, tool-minimal field replacement in UPS and panel installations.
  • Rated for a wide ambient operating temperature range of -20°C to 60°C, suiting both conditioned and unconditioned equipment rooms.
  • Compact footprint and standard NP12-12 form factor make it a drop-in replacement across most UPS and control panel battery compartments.

Industrial Applications

The Yuasa NP12-12 is widely used as the standby battery of choice in small-to-medium uninterruptible power supplies protecting server rooms, building management systems, and DCS operator stations, as well as in fire alarm control panels, access control and CCTV power supplies, and emergency lighting systems across commercial and industrial facilities. The Yuasa NP12-12’s combination of float and cyclic duty capability also makes it suitable for solar-charged remote monitoring stations and portable instrumentation power packs deployed at pipeline right-of-way and remote wellhead sites.

As the officially authorized partner for Yuasa, Seven Star LLC distributes the NP12-12 to facility maintenance teams, UPS service contractors, and panel builders throughout Muscat, the Sohar Freezone and Port, Salalah’s logistics and port zone, and across the Sultanate of Oman’s oil, gas, and desalination sectors, providing dependable, genuine replacement batteries for critical standby power systems throughout Oman and the wider GCC.
