Detailed specifications and benefits
The PS‑1212VdS is compact but thoughtfully specified for real‑world standby use. Key physical and electrical specifications include:
- Model: PS‑1212VdS (FR denotes flame‑retardant case option).
- Nominal voltage: 12.0 V.
- Capacity: 1.20 Ah (20‑hr rate); 1.12 Ah @ 10‑hr.
- Dimensions (L × W × H): 97 × 43 × 52 mm; height over terminal ≈ 58 mm.
- Weight: ≈0.6 kg.
- Case material: ABS (UL94:HB), UL94:V‑0 for FR variant.
- Terminal type: F1 Faston (0.187" / 4.7 mm).
- Design life: ≈5 years (float service).
- Approvals: VdS, NCP, UL recognised; approved for air transport (DOT / IATA / FAA).
- Manufacturing standard: ISO 9001.
Benefits that flow from these specifications:
- Reliability: AGM construction traps electrolyte in glass fibres, making the battery leak‑proof and less prone to maintenance issues compared with flooded lead‑acid cells.
- Safety and compliance: VdS and NCP approvals mean the PS‑1212VdS meets recognised standards for life‑safety equipment (fire detection, emergency lighting, etc.), and the FR case option adds an extra layer of fire protection where required.
- Ease of installation: F1 Faston terminals are widely used and allow quick, secure connections without special tooling.
- Transportable: Recognised for air transport simplifies logistics when batteries are shipped for replacement or deployment.
- Compact form factor: Small footprint and low weight make the battery suitable for tight enclosures and portable standby devices.
Use cases and where the PS‑1212VdS excels
Because of its size, chemistry and approvals, the PS‑1212VdS is particularly well suited to a range of standby and life‑safety roles. Typical applications include:
- Emergency lighting: Compact size means the battery fits into most emergency luminaires and central battery systems requiring small backup sources.
- Fire alarm and detection systems: VdS approval and dependable float performance make it an appropriate choice for fire panels and associated ancillary equipment.
- Security systems: Alarm panels, access control units and motion‑sensor backup benefit from the sealed, maintenance‑free design and easy Faston connections.
- Small uninterruptible power supplies (UPS): For low‑power UPS modules that support telecom, network appliances or point‑of‑sale devices during short outages.
- Medical devices and portable equipment: Where a regulated, sealed battery is required for safety and reliability in compact devices.
- Backup and remote sensors: Remote instrumentation and monitoring nodes that need a small, long‑life battery for standby use.
In short, the PS‑1212VdS excels wherever certified, compact standby power is needed and where long float life, sealed construction and common connectors simplify installation and maintenance.
Comparisons with similar products on the market
Choosing a backup battery often means balancing chemistry, size, approvals and cost. Here are common comparisons to consider when evaluating the PS‑1212VdS against alternatives:
Other 12 V SLA batteries with similar capacities exist, but the PS‑1212VdS stands out for its blend of approvals and options. Models without VdS/NCP approval may be cheaper but are not suitable for certified life‑safety installations. The FR (flame‑retardant) case option is an important differentiator in installations with stricter fire safety requirements.
Larger Ah batteries will provide longer run times but are physically bigger and heavier. For applications where space is limited or the power draw is modest (alarm panels, small UPS), a 1.2 Ah battery like the PS‑1212VdS is often the optimal compromise between size and runtime. Selecting a larger battery can be unnecessary and may cause fitting issues in purpose designed enclosures.
Lithium chemistries (LiFePO4 or Li‑ion) can offer higher energy density and longer cycle life but usually at higher upfront cost, more complex charging requirements and sometimes stricter transport considerations. For certified life‑safety installations, lead‑acid VRLA batteries like the PS‑1212VdS remain the common choice because of widespread acceptance, standard charging infrastructure and regulatory familiarity.
At a suggested retail price of approximately $10.99, the PS‑1212VdS provides a cost‑effective solution for certified small‑capacity standby needs. It balances reliable brand manufacturing and approvals without the premium associated with higher‑capacity or alternative chemistry options.
Customer feedback and typical user experiences
Specific customer reviews for this exact model may vary by reseller and installation, but common and recurring feedback from installers, system integrators and end users includes:
- Dependable service life in emergency lighting and alarm systems when charged properly and used in a suitable float application.
- Ease of handling and installation due to the compact size and lightweight construction — especially helpful for retrofit jobs and confined compartments.
- Appreciation for F1 Faston terminals because they match the connectors already present in many fire and security enclosures, reducing the need for adapter cables.
- Positive comments about the availability of a flame‑retardant case option for installations with stricter fire safety specifications.
- Noted that correct charger selection and adherence to manufacturer charge profiles are important for maximising service life.
