Sealed Lead-Acid Battery FUKAWA FW 7.2-12 F2U 12V 7.2Ah Faston 6.3mm, 5-year design life

The FUKAWA FW 7.2-12 F2U is a sealed lead-acid (SLA) battery providing a nominal voltage of 12 V and a capacity of 7.2 Ah. Designed for both standby and cyclic operation, this maintenance-free battery features Faston 6.3 mm (F2) terminals for reliable, quick connections and a specified design life of five years. Its compact sealed construction makes it suitable for installation in confined enclosures and devices where low maintenance and predictable service life are required.

Advantages

The battery offers stable voltage output and consistent capacity across typical operating conditions, with a sealed, maintenance-free design that eliminates the need for periodic electrolyte checks. Faston 6.3 mm terminals simplify installation and replacement in existing systems. A five-year design life provides predictable replacement intervals for planning maintenance in UPS, emergency lighting and alarm applications.

Suitable for

• Uninterruptible Power Supply (UPS) systems for small to medium loads
• Emergency and exit lighting circuits
• Alarm and security control panels
• Small telecommunications and network backup devices
• Portable testing equipment and standby power modules

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 7.2 Ah
• Terminal type: Faston 6.3 mm (F2)
• Battery type: Sealed lead-acid (SLA), valve-regulated
• Design life: 5 years (specified)
• Maintenance: Maintenance-free, sealed construction

How to use

Install the battery in accordance with the device manufacturer’s instructions, ensuring correct polarity and secure connections to the Faston 6.3 mm terminals. Use within the recommended temperature and charging parameters of the host equipment to achieve the specified design life. For standby applications, keep the battery on float charge per the equipment’s charging profile; for cyclic use, follow the proper charge/discharge algorithm recommended by the system manufacturer. Observe standard safety practices when handling lead-acid batteries, including avoiding short circuits and installing in a ventilated enclosure if specified by the system.

Usage recommendations

To maximize service life and performance, store and operate the battery within the manufacturer-recommended temperature range, maintain appropriate charging regimes (float charge for standby, controlled charge for cyclic use), and replace according to planned maintenance intervals near the five-year design life. Dispose of the battery following local regulations for lead-acid battery recycling.
