12V 150Ah SLA Battery

CBL150-12  |  12V 150Ah Sealed Lead Acid Battery  |  1,800Wh  |  T11 (M8 Threaded Insert)  |  95.3 lbs (43.2 kg)  |  Lead Calcium Alloy  |  UL 1989 Certified

The Canbat 12V 150Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for large-format industrial standby and light cyclic applications requiring maximum reserve capacity, reliable float performance, and extended service life. 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 a 20+ year design floating life at 20°C. Rated at 150Ah and 1,800Wh with an internal resistance of approximately 3.5mΩ — the lowest in the Canbat CBL series — the CBL150-12 is suited to large UPS systems, telecommunications base stations, data centre backup, and mission-critical industrial standby power installations requiring high reserve capacity and reliable long-term float performance. Certified to UL 1989.

Typical Applications

The CBL150-12 12V 150Ah SLA battery is designed for large-format industrial standby and light cyclic applications where maximum reserve capacity, extended runtime, and reliable high-current delivery under sustained float conditions are required. Rated at 150Ah (C20) at 12V, this 12V 150Ah SLA battery is suited to large commercial UPS systems, telecommunications infrastructure, and industrial standby power installations where long service life and minimal maintenance are critical requirements. Typical deployment includes large UPS backup power systems, telecommunications base stations, network infrastructure, data centre backup power, fire alarm systems, emergency lighting systems, industrial control systems, electric power systems (EPS), building automation controls, security systems, solar backup power systems, and mission-critical DC control systems. The CBL150-12 is commonly used as a replacement 12V 150Ah SLA and AGM battery in large UPS systems, telecommunications infrastructure, data centre backup systems, fire alarm systems, industrial standby power installations, and emergency lighting systems.

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 CBL150-12 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 CBL150-12 12V 150Ah 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.
