12V 55Ah SLA Battery

Description CBL55-12  |  12V 55Ah Sealed Lead Acid Battery  |  660Wh  |  Group 22NF  |  T9 (M8 Lug Terminal)  |  35.7 lbs (16.2 kg)  |  Lead Calcium Alloy  |  UL 1989 Certified The Canbat 12V 55Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for commercial UPS systems, fire alarm and security installations, emergency lighting, medical devices, and standby power applications requiring high reserve capacity and reliable high-current delivery. 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. Built to Group 22NF dimensions and rated at 55Ah and 660Wh, the CBL55-12 is fitted with T9 (M8 lug) terminals rated for bolted cable connections — suited to commercial and institutional standby power installations across Canada. Certified to UL 1989. Typical Applications The CBL55-12 12V 55Ah SLA battery is designed for commercial standby and cyclic applications where high reserve capacity, extended runtime, and heavy-duty terminal connections are required. Rated at 55Ah (C20) at 12V and built to Group 22NF dimensions, this 12V 55Ah SLA battery is suited to commercial UPS systems, fire alarm systems, emergency lighting installations, security systems, and medical device backup power. Typical deployment includes UPS backup power systems, fire alarm systems, emergency lighting systems, security alarm systems, access control systems, medical devices, electric power systems (EPS), building automation controls, telecommunications infrastructure, network equipment, industrial control systems, floor scrubbers, power wheelchairs, and small solar backup systems. The CBL55-12 is commonly used as a replacement 12V 55Ah SLA and AGM battery and Group 22NF battery in UPS systems, fire alarm systems, emergency lighting installations, security systems, medical devices, 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 CBL55-12 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 CBL55-12 12V 55Ah 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.
