PS412 (12V 4Ah) – Rechargeable Sealed Lead Acid (SLA / AGM) Backup Battery

Product Overview

The PS412 (12V 4Ah) (Dimensions: 90 x 70 x 101/107 mm / 3.54''  2.76'' x 3.98''/4.21'') is a heavy-duty, rechargeable Sealed Lead Acid (SLA) battery engineered with Absorbent Glass Mat (AGM) technology. Designed for high-reliability standby backup power and cyclic applications, it provides dependable DC energy storage for security control panels, fire alarms, access control systems, UPS battery backups, emergency lighting, and electronic test equipment.

Built with a valve-regulated, spill-proof architecture, the PS412 ensures maintenance-free operation and safe mounting in any physical orientation without the risk of acid leakage. Its durable, high-impact ABS plastic casing delivers superior resistance against vibration, heat, and physical shocks, while standard F1 (0.187'' / 4.75 mm) quick-disconnect faston terminal tabs guarantee fast, secure, and low-resistance electrical connections across commercial and residential low-voltage systems.

Key System Features & Functionality

• Advanced AGM Technology: Utilizes micro-porous glass fiber separators to immobilize the electrolyte, optimizing internal recombination efficiency and lowering self-discharge rates.

• Maintenance-Free & Spill-Proof: Valve Regulated Lead Acid (VRLA) sealed design eliminates the need for water replenishment and prevents corrosive gas/acid leaks.

• Multi-Position Installation: Safe to install and operate vertically or on its side without loss of capacity or risk of leakage.

• Standard F1 Faston Terminals: Outfitted with standard 4.75 mm (0.187'') F1 quick-connect spade terminals for effortless plug-and-play wiring.

• Low Self-Discharge Rate: High-purity lead-calcium grid alloy ensures extended shelf life and standby readiness during storage.

• High-Impact Flame-Retardant ABS Enclosure: Rugged case protects internal cells against vibrations, drops, and temperature fluctuations.
