The Century PS PS12120L is a high-performance, multi-purpose 12V VRLA battery engineered to provide dependable primary and backup power for critical domestic and commercial configurations. Manufactured to strict International standards using premium-grade raw materials and advanced assembly routines, this 5-year design life stationary battery ensures trouble-free operation over extended periods. It serves as an ideal backup reserve power unit to keep your electronic systems completely operational during sudden mains power disruptions.
Perfect for users who demand:
- ✓ Unfailing backup reserve power to operate critical security, medical, and control systems
- ✓ Advanced gas-recombinant VRLA technology for a completely maintenance-free operational life
- ✓ A compact, vibration-resistant power cell optimised for high-service-life applications
Key Features & Benefits
Absorbed Glass Mat Technology
- • High-porosity glass fibre mat separators entirely absorb and suspend the liquid electrolyte
- • Minimises internal resistance while successfully safeguarding against dangerous leaks and spills
- • Balances uniform current distribution to ensure electrical stability across long float cycles
Valve Regulated VRLA Design
- • Recombinant framework successfully seals down internal fluid vapour and gas pathing
- • Enables convenient, flexible fitment in hard-to-reach, enclosed, or poorly ventilated cabinets
- • Prevents premature capacity drops or loss of life without regular water top-ups
International Quality Standards
- • Crafted to elite international benchmarks utilising premium-grade raw materials
- • Complies in full with strict IEC60896-22:2004 stationary battery parameters
- • Designed to maximise service durability and resist early cell grid degradation
Vibration & Fitting Security
- • Vibration-resistant casing shields fragile active materials from internal shock damage
- • Compact 3.87 kg structure integrates easily into standard emergency system trays
- • Wide T2 Faston terminal pins facilitate low-resistance, high-reliability connection paths
Advantages & Considerations
Advantages
- ✓ Substantial 5-year design life under proper float and standby charging environments
- ✓ Generous 12 Ah capacity offers extended runtime for constant-load electronics
- ✓ Leak-proof layout ensures surrounding circuitry and cabinets remain fully protected
- ✓ Covered by a dependable 12-month domestic and commercial warranty
Considerations
- • Equipped with standard wider T2 terminals; check connection spade compatibility
- • Not formalised or calibrated to support the high current draw of vehicle engine cranking
- • Tailored primarily for standby/float configurations rather than frequent deep daily cyclic discharges
Frequently Asked Questions
What is the lifespan of this battery?
In continuous float or standby installations, this high-performance cell offers a 5-year design life. Final longevity relies on maintaining stable operating temperatures and avoiding incorrect overcharging practices.
Is this battery maintenance-free?
Yes, this model features a completely Sealed Maintenance-Free (SMF) VRLA architecture. Internal gas recombination is handled safely inside the container, meaning it never requires fluid level checks or water top-ups.
What applications is this battery compatible with?
The Century PS12120L is ideally formalised for uninterruptible power supplies (UPS), domestic security alarm setups, commercial fire panels, exit lighting, medical devices, and automated electronic back-ups.
How should I store this battery during the off-season?
Store the unit in a cool, dry indoor environment out of direct climate extremes. Ensure it is charged up entirely before storage, and use a compatible smart charger like the CC6121.2 or CC1206-XLi periodically to counteract natural self-discharge trends.
What is covered under the warranty?
This battery includes a 12-month warranty. It protects against unexpected internal failures caused directly by factory material anomalies or structural build errors, subject to the conditions detailed on the attached statement.
