Description
CBL12-12 | 12V 12Ah Sealed Lead Acid Battery | 144Wh | F2 Terminal | 7.14 lbs (3.43 kg) | Lead Calcium Alloy | UL 1989 Certified
The Canbat 12V 12Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for higher-load 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 12Ah and 144Wh, the CBL12-12 provides substantially greater reserve capacity than compact 7Ah–10Ah standby batteries and is suited to commercial UPS systems, telecommunications infrastructure, and network equipment requiring reliable extended-duration backup power. Certified to UL 1989.
Typical Applications
The CBL12-12 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 12Ah (C20) at 12V, the battery is suited to higher-load UPS systems, telecommunications infrastructure, and network equipment where reserve capacity and runtime are primary requirements. Typical deployment includes UPS backup power systems, telecommunications infrastructure, network equipment, fire alarm systems, emergency lighting systems, access control systems, electric power systems (EPS), communication power supplies, building automation controls, DC control systems, and medical monitoring equipment. The CBL12-12 is commonly used as a replacement 12V 12Ah 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
The CBL12-12 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 CBL12-12 12V 12Ah 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.

Olivia R. –
I got this 12Ah battery as a replacement for my UPS. It had the exact dimensions needed for my UPS. Haven’t really tested it much yet because we don’t get too many power outages down here, but it powered up the UPS and things look great so far. Oh and it only arrived in a few days, which is much faster than expected! Great battery company.
