The battery measures 5.94 inches long, 2.56 inches wide, and 3.84 inches high, weighs approximately 4.85 pounds, and features a durable ABS housing. With a design life of up to five years at 68 F (20 C) under appropriate standby conditions, the NP7-12 supports reliable emergency power in residential, commercial, and institutional installations.

Yuasa NP7-12 12V 7Ah AGM Sealed Lead-Acid Rechargeable Backup Battery

The Yuasa NP7-12 Rechargeable Sealed Lead-Acid Battery provides compact, dependable 12V backup power for commercial and residential electronic systems requiring a maintenance-free rechargeable energy source. Manufactured by GS Yuasa as part of its NP Series of general-purpose valve-regulated lead-acid (VRLA) batteries, the NP7-12 delivers a nominal capacity of 7.0 amp-hours at the 20-hour discharge rate, making it suitable for standby applications and light cyclic service. The battery is commonly used in compatible intrusion alarm control panels, fire alarm equipment, electronic access control systems, emergency lighting units, communication equipment, and uninterruptible power supplies. During normal standby operation, a compatible charging circuit maintains the battery at the specified float voltage. When primary electrical power is interrupted, the battery supplies stored electrical energy to the connected equipment for a duration determined by the system load, available capacity, and battery condition. Its compact housing and standard quick-connect terminals support replacement in appropriately sized power supply enclosures and security system battery compartments. The NP7-12 can also be connected in approved series or parallel arrangements where the equipment manufacturer specifies a different system voltage or increased capacity.

The NP7-12 incorporates Absorbent Glass Mat (AGM) electrolyte suspension technology and lead-calcium alloy grids to provide efficient gas recombination, low self-discharge, and maintenance-free operation. Its internal microfiber glass separators retain the sulfuric acid electrolyte, eliminating free-flowing liquid under normal operating conditions, while individual low-pressure safety valves release excess gas when necessary and automatically reseal afterward. The battery features a nominal 12V output and 7Ah capacity at the 20-hour rate to 1.75 volts per cell at 20 C, with a reduced capacity of 6.4Ah at the 10-hour discharge rate to 1.8 volts per cell. The manufacturer specifies physical dimensions of 151 mm (5.94 inches) long, 65 mm (2.56 inches) wide, and 97.5 mm (3.84 inches) high including terminals, with a typical weight of approximately 2.2 kg (4.85 pounds). The battery uses 4.75 mm (0.187-inch) Faston quick-connect terminals and a standard ABS housing with a UL94 HB material flammability classification. Manufacturer specifications identify approximately 25 milliohms of internal resistance, a maximum one-second discharge current of 210 amps, and a maximum one-minute discharge current of 48 amps. These short-duration discharge values describe battery performance limits rather than recommended continuous operating current.

For standby power and light cyclic applications, the Yuasa NP7-12 supports regulated float charging and periodic discharge operation when connected to a compatible lead-acid battery charging system. The manufacturer specifies a float charging voltage of 13.65V 1% at 20 C (68 F) and a cyclic or boost charging voltage of approximately 14.5V 3% at 20 C. The published maximum charging current is 1.75 amps for the referenced battery specification. Charging voltage requires appropriate temperature compensation because battery operating temperature affects charging efficiency, available capacity, and long-term service life. The NP7-12 has a manufacturer-rated design life of up to five years at 20 C under suitable float-service conditions and belongs to the EUROBAT Standard Commercial 3-5 Year battery category. Actual replacement intervals depend on installation temperature, charging voltage, discharge depth, operating cycles, and connected equipment requirements. The manufacturer's operating temperature ranges are -4 F to 140 F (-20 C to 60 C) for discharge, 5 F to 122 F (-15 C to 50 C) for charging, and -4 F to 140 F (-20 C to 60 C) for storage of a fully charged battery. At 20 C, the battery typically loses approximately 3% of its capacity per month during storage, making periodic charging important when batteries are stored before installation.

Installation of the Yuasa NP7-12 12V 7Ah AGM battery requires verifying the connected equipment's battery voltage, minimum capacity, charger compatibility, terminal dimensions, and available enclosure space. The standard 0.187-inch Faston terminals accommodate matching female quick-disconnect connectors, allowing installation without soldering or specialized terminal adapters. When replacing an existing battery, technicians disconnect the equipment's primary electrical supply according to the manufacturer's instructions, remove the existing battery connections, and connect the replacement with the correct positive and negative polarity. For equipment requiring a 24V standby supply, two compatible 12V batteries may be connected in series when specifically permitted by the host equipment manufacturer. The sealed AGM design supports operation in orientations up to 90 degrees from upright, although permanent inverted installation is not permitted under current manufacturer guidance. Batteries must be installed in appropriately ventilated enclosures because VRLA technology can release hydrogen during abnormal charging or overcharge conditions. Routine maintenance includes verifying charging voltage, inspecting terminal connections, monitoring battery condition, and performing manufacturer-approved standby capacity tests. The NP7-12 is distinct from Yuasa NP7-12FR flame-retardant variants and configurations using different terminal sizes, so physical and electrical compatibility must be confirmed before substitution. At the end of its service life, the lead-acid battery must be recycled through an approved battery recycling program rather than discarded with ordinary waste. Combining 12V 7Ah capacity, AGM construction, low-maintenance standby performance, compact dimensions, and a five-year design-life classification, the Yuasa NP7-12 provides a versatile rechargeable backup battery for commercial security, emergency power, and electronic control applications.
