12V 18Ah SLA Battery

Description CBL18-12  |  12V 18Ah Sealed Lead Acid Battery  |  216Wh  |  NB Terminal  |  11.9 lbs (5.15 kg)  |  Lead Calcium Alloy  |  UL 1989 Certified The Canbat 12V 18Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for commercial standby and light cyclic applications requiring higher reserve capacity and longer backup duration. Featuring lead calcium alloy plate construction and absorbent glass mat (AGM) technology, the battery delivers maintenance-free operation, a self-discharge rate below 2% per month, and reliable float performance across a 20 year design floating life at 20°C. Rated at 18Ah and 216Wh, the CBL18-12 provides substantially greater reserve capacity than 14Ah standby batteries and is fitted with NB (nut and bolt) terminals suited to higher-current commercial standby installations. Certified to UL 1989. Typical Applications The CBL18-12 is designed for float standby and light cyclic discharge duty in commercial standby power systems requiring higher reserve capacity and extended backup duration. Rated at 18Ah (C20) at 12V, the battery is suited to small-to-medium UPS systems, commercial alarm and security systems, fire alarm panels, emergency lighting installations, and access control infrastructure requiring greater runtime than compact 14Ah standby batteries. Typical deployment includes UPS backup power systems, alarm systems, fire alarm systems, emergency lighting systems, access control systems, electric power systems (EPS), communication power supplies, building automation controls, DC control systems, and telecommunications infrastructure. The CBL18-12 is commonly used as a replacement 12V 18Ah SLA and AGM battery in UPS systems, alarm systems, fire alarm systems, emergency lighting installations, access control systems, and commercial standby power applications. UL 1989 Certification UL 1989 certification provides third-party verification of battery safety and performance requirements commonly specified for Canadian commercial and institutional installations. Certified batteries are frequently selected for fire alarm, emergency lighting, telecommunications, security, and standby power systems where engineers, contractors, and Authorities Having Jurisdiction (AHJs) require documented product certification. The CBL18-12 is certified to UL 1989, the Underwriters Laboratories standard for sealed lead acid batteries, covering electrical performance, mechanical integrity, and safety requirements including overcharge tolerance and short circuit protection. Certification is issued following independent third-party laboratory evaluation — not manufacturer self-declaration. Canbat maintains UL 1989 certification across its sealed lead acid battery lineup. VRLA AGM Construction The CBL18-12 12V 18Ah SLA battery uses valve-regulated absorbent glass mat (AGM) construction, with electrolyte immobilized within puncture resistant micro-porous glass mat separators. The sealed recombinant cell design prevents acid emission under normal operating conditions and permits installation in any orientation. Lead calcium alloy plate construction eliminates watering requirements, reduces gassing, and supports low self-discharge performance. Batteries stored at 25°C may be held up to six months before a refresh charge is required; storage at elevated temperatures reduces this interval.
