12V 20Ah SLA Battery

CBL20-12  |  12V 20Ah Sealed Lead Acid Battery  |  240Wh  |  M5 Terminal  |  12.74 lbs (5.78 kg)  |  Lead Calcium Alloy  |  UL 1989 Certified

The Canbat 12V 20Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for higher-load commercial standby and light cyclic applications requiring extended backup runtime. 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 20Ah and 240Wh, the CBL20-12 is suited to commercial UPS systems, telecommunications infrastructure, and network equipment where higher reserve capacity and extended runtime are primary requirements. Certified to UL 1989.

Typical Applications

The CBL20-12 12V 20Ah SLA battery is designed for float standby and light cyclic discharge duty in commercial and institutional backup power systems requiring higher capacity and extended runtime. Rated at 20Ah (C20) at 12V, this 12V 20Ah SLA battery is suited to higher-load UPS systems, telecommunications infrastructure, and network equipment where reserve capacity and runtime exceed the requirements of compact 18Ah standby batteries. Typical deployment includes UPS backup power systems, telecommunications infrastructure, network equipment, fire alarm systems, emergency lighting systems, access control systems, building automation controls, electric power systems (EPS), communication power supplies, DC control systems, and commercial standby power installations. The CBL20-12 is commonly used as a replacement 12V 20Ah SLA and AGM battery in UPS systems, telecommunications equipment, network equipment, fire alarm systems, emergency lighting installations, 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 CBL20-12 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 CBL20-12 12V 20Ah 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.
