Description
CBL4.5-12 | 12V 4.5Ah Sealed Lead Acid Battery | 54Wh | F1 Terminal | 3.06 lbs (1.39 kg) | Lead Calcium Alloy | UL 1989 Certified
The Canbat 12V 4.5Ah SLA battery is a valve-regulated sealed lead acid (VRLA) battery designed for standby and light cyclic applications. 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. The compact footprint — 3.54 × 2.76 × 3.98 in — accommodates standard enclosure formats across security, life-safety, and access control infrastructure. Certified to UL 1989.
Typical Applications
The CBL4.5-12 is designed for float standby and light cyclic discharge duty in systems requiring compact, sealed 12V backup power. Rated at 4.5Ah (C20) at 12V, the battery is suited to moderate standby loads and longer backup runtimes than ultra-compact 12V SLA batteries. Typical deployment includes alarm and security systems, fire detection panels, emergency lighting equipment, exit sign backup units, access control systems, garage door openers, UPS backup power, electric power systems (EPS), communication power supplies, DC control systems, medical monitoring equipment, and telecommunications infrastructure. The CBL4.5-12 is commonly used as a replacement 12V 4.5Ah SLA and AGM battery in security systems, alarm panels, emergency lighting equipment, access control systems, garage door openers, and UPS installations.
UL 1989 Certification
The CBL4.5-12 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. UL 1989 certification is commonly specified for security, fire alarm, emergency lighting, telecommunications, and backup power installations.
VRLA AGM Construction
The CBL4.5-12 12V 4.5Ah 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.

Been buying these batteries for alarm systems and installing them for my clients. Working great and never a complaint.

I bought this for my orange job rocker that I bought in 2013. The battery needed replacing so I don’t have to have it plugged in all the time. The battery arrived in only 3 days and now the Job rocker will play my tunes nicely on my boat.
