Detailed Specifications and Benefits
The PS-12120VDS delivers 12.00 Ah at the 20‑hour rate, with rated capacities of 11.20 Ah at 10 hours, 10.20 Ah at 5 hours and 7.49 Ah at 1 hour. Internal resistance is low (~14.0 mΩ), enabling good discharge performance and efficient recharge. Short‑duration discharge capability is significant — the battery can deliver up to 120 A for short bursts (10 s), useful for powering pumps, alarms or brief high-load events.
AGM VRLA technology traps electrolyte in glass mats between plates, making the battery spill‑proof and maintenance‑free; there is no need to add water or perform periodic cell checks. The flame‑retardant ABS case (UL94‑V0) is a key differentiator for installations where reduced flame propagation is required by regulations or insurer specifications. VdS and NCP approvals further ensure suitability for certified fire detection and alarm systems.
At approximately 3.5 kg with compact dimensions of 151 × 98 × 95 mm (L×W×H), this battery is easy to mount in cabinets and enclosures. Operating temperature windows are broad: -20°C to +60°C for discharge and -15°C to +50°C for charging. Float charge at 20°C is 2.25–2.30 V/cell (13.5–13.8 V for a 12 V battery), with cyclic charge guidance of 2.35–2.45 V/cell (≈14.1–14.7 V for 12 V) — important to ensure longevity and reliable standby performance.
This model carries VdS and NCP approvals and UL recognition, and manufacturing quality aligns with ISO9001:2015. It is approved for air transport with applicable IATA/ICAO/DOT/FAA markings. The design life is typically 5 years in standby service when installed and maintained according to manufacturer recommendations — a practical lifetime for many fire and security installations.
Use Cases and Scenarios Where the PS-12120VDS Excels
- Fire alarm and detection systems:VdS and NCP approvals plus a flame‑retardant case make this battery ideal for certified emergency power in detection and alarm panels where local codes or insurers require approved components.
- Emergency lighting:Consistent float performance and a maintenance‑free design suit emergency luminaires and signage that must remain operational during mains interruptions.
- Security and intrusion systems:Reliable standby power and fast current delivery for short alarm events make it a good match for control panels, sirens and communication devices.
- Small UPS and telecom backup:For point-of-load UPS modules or small servers that need minutes to an hour of runtime, the PS‑12120VDS is compact enough to fit many rack and enclosure environments.
- Medical and life‑safety equipment:Where approvals, predictable backup time and safety (flame‑retardant housing) matter, this battery can serve in diagnostic equipment, monitoring devices and portable emergency gear.
Comparisons with Similar Products on the Market
When choosing a 12 V 12 Ah battery, buyers typically compare AGM VRLA options between manufacturers and also consider alternative chemistries like gel lead‑acid or lithium‑ion. Here’s how the PS‑12120VDS stacks up:
Many 12 Ah AGM batteries offer similar electrical characteristics, but the PS‑12120VDS stands out with VdS and NCP approvals and the flame‑retardant UL94‑V0 ABS case. For fire/safety installations that require certified components or specific case flammability ratings, the PS‑12120VDS reduces installation friction and compliance risk. In addition, low internal resistance and robust short‑circuit current capability give it an edge in high‑load events.
Gel batteries are valued for deep‑cycle resilience in some cyclic applications but are typically less tolerant of high charge currents and may be more sensitive to charging regime. AGM batteries like the PS‑12120VDS generally offer better high‑rate discharge capability and more flexible charging characteristics for standby applications. For emergency and standby use — where float charge and occasional discharge are typical — AGM is often preferred.
Lithium‑ion solutions deliver higher energy density, lighter weight and longer cycle lives, but they are more expensive up front and often require specialized battery management systems (BMS) and different compliance paperwork for certified fire/security installations. For regulated environments that require VdS/NCP approval or flame‑retardant housings, a certified AGM like the PS‑12120VDS remains a practical and cost‑effective option.
Practical Considerations for Installation and Maintenance
- Terminal type:This SKU comes with F1 (Faston 0.187") terminals — confirm the terminal style (F1 vs F2) before ordering to match connector hardware and enclosure designs.
- Charging:Use a charger configured for sealed lead‑acid AGM batteries, observing float and cyclic voltage guidance to maximize life.
- Storage:Store batteries in a cool, dry place and recharge periodically during long storage to avoid deep self‑discharge.
- Safety:Avoid shorting terminals, do not disassemble, and follow local recycling/disposal rules for lead‑acid batteries.
Customer Feedback and Reviews
Below are representative customer comments collected from installers and end‑users who have deployed the PS‑12120VDS in real systems. These reflect common strengths and practical observations:
