Yuasa Y7-12FR 12V 7Ah AGM VRLA Battery, Faston Tabs Y7-12FR

Introduction to the Yuasa Y7-12FR and its key features

The Yuasa Y7-12FR is a compact, sealed 12 V, 7.0 Ah Absorbed Glass Mat (AGM) lead‑acid battery built for reliability in standby and short‑run backup applications. As a VRLA (valve regulated lead‑acid) product with an optional flame‑retardant (FR) case and Faston tab terminals, it combines safety, convenience and proven chemistry from a long‑established battery manufacturer. Whether you are specifying replacements for alarm panels, emergency lighting units, small UPS systems or telecom modules, the Y7-12FR is designed to deliver stable, maintenance‑free power with straightforward installation.

• Nominal voltage:12 V;Capacity:7.0 Ah (20‑hr rate).
• Construction:AGM / VRLA — sealed and maintenance‑free with low self‑discharge.
• Terminals:Faston / tab ≈4.75–4.8 mm for quick, reliable connections.
• Safety option:Flame‑retardant (FR) case variant for fire‑safety sensitive installations.
• Design life:Eurobat standard commercial (approx. 3–5 years in standby service).

Detailed specifications and the practical benefits they deliver

Understanding the Y7-12FR starts with its technical profile. The battery’s 12 V nominal voltage and 7.0 Ah capacity (measured at the 20‑hour discharge rate to 1.75 V per cell at 20°C) make it a common choice for loads that require dependable, short‑duration backup rather than long‑term deep cycling. Below are the notable specifications and what they mean for real‑world use.

• Nominal voltage:12 V — compatible with most small standby systems, UPS modules and alarm equipment.
• Capacity:7.0 Ah (20‑hr); ~6.4 Ah at the 10‑hr rate — provides predictable run times for typical security and emergency lighting loads.
• Float charge voltage:13.65 V ±1% at 20°C — optimized for long‑term standby service and minimal water loss (AGM recombination).
• Cyclic/boost voltage:14.5 V ±3% at 20°C — recommended when the battery is used in cyclic applications or after discharge.
• Recommended max charge:cyclic limit ≈1.75 A — supports safe charging rates for the battery’s capacity class.
• Terminals:Faston/tab ≈4.75–4.8 mm — speeds up installation and replacement compared with screw posts or bolt‑on types.

• Dimensions:Length 151 mm, Width 65 mm, Height 94.5 mm (100 mm over terminals) — a compact footprint suitable for many battery compartments.
• Mass:Typical ≈2.2 kg (vendor listings vary 2.45–2.7 kg) — light enough for easy handling but substantial enough to indicate robust internal construction.
• Operating temperature:Broad range (approx. −20 °C to +60 °C) — consult the datasheet for exact performance curves and temperature compensation needs.
• Recycling / disposal:Sealed lead‑acid chemistry — recyclable but must be handled under local hazardous waste regulations.

AGM VRLA construction makes the Y7-12FR maintenance‑free: there’s no need to add water and the recombination design reduces gas escape during normal use. The Faston tabs enable fast, secure connections typical in alarm and lighting panels, reducing installation time and contact reliability issues. The FR case option is particularly beneficial where fire safety standards or local codes recommend flame‑retardant enclosures.

Use cases and scenarios where the Y7-12FR excels

This battery is optimized for standby and short‑duration backup roles. Typical, high‑value applications include:

• Intruder and fire alarm systems:Most alarm control panels specify 12 V lead‑acid batteries in the 4–12 Ah range. The Y7-12FR provides stable reserve power for detectors, sirens and communications when mains power fails.
• Emergency lighting:Designed to hold charge and provide the required short emergency illumination periods; the FR case option supports installations in escape route fittings where safety standards are strict.
• Small UPS and telecom equipment:For compact uninterruptible power supplies and telecom backup modules needing short run‑times to cover orderly shutdown or handover to a generator.
• Service and replacement stock:Contractors often keep a 12 V/7 Ah battery on hand for quick field swaps because its size and capacity match many common legacy fixtures.
• DIY and light industrial uses:Home backup gadgets, portable power projects and small off‑grid devices where sealed, spill‑proof batteries are preferred.

Comparisons with similar products on the market

When choosing a 12 V, 7 Ah battery there are several considerations: manufacturer reputation, case material (standard vs FR), terminal type, internal construction (AGM vs gel vs flooded), and price. The Y7-12FR stands out for a few reasons:

• Brand and quality:Yuasa is a well‑established battery maker with a long track record in lead‑acid technologies. That history tends to translate into consistent manufacturing quality and reliable supply of datasheets and support.
• FR case option:Not all competitors provide the flame‑retardant housing; this can be a deciding factor where fire safety certifications matter.
• Terminals:Faston tabs are common in security and lighting applications. Competing models sometimes use screw terminals or bolt posts which may be slower to install or require adapter hardware.
• AGM vs gel or lithium:AGM offers a good balance of cost, tolerance to moderate currents and maintenance‑free operation. Gel batteries can perform better in deep‑discharge cyclic work, while lithium variants provide higher energy density and longer cycle life but at a much higher cost and with different charging requirements.
• Value:At a suggested price point in the mid‑teens (retail guidance often around £16.99, with cost supply figures lower), the Y7-12FR is competitively priced for contractors and end users seeking a reliable OEM‑quality battery without the premium of specialty chemistries.

Customer testimonials and typical feedback

Publicly available customer feedback for 12 V/7 Ah AGM batteries tends to highlight a few recurring themes — reliability, fitment compatibility and value. Below are representative points commonly mentioned by installers and end users (these are synthesized, anonymized summaries rather than direct quotes):

• "Easy to swap into alarm and emergency lighting units thanks to the Faston tabs and compact dimensions."
• "Solid, reliable hold‑up time for short backup runs — meets expectations for a 7 Ah class battery."
• "The flame‑retardant case gives extra peace of mind in installations that require enhanced safety."
• "Good balance of cost and quality compared with unbranded alternatives; Yuasa’s documentation is helpful for specifying charge voltages and handling."

Some users note that for deep cyclic use or very extended runtimes a larger capacity or different chemistry (e.g., lithium) may be preferable, which aligns with the battery’s intended standby role.
