Description
CBL4-6 | 6V 4Ah Sealed Lead Acid Battery | 24Wh | T1 Terminal | 1.43 lbs (0.65 kg) | Lead Calcium Alloy | UL 1989 Certified
The Canbat 6V 4Ah 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 — 2.76 × 1.85 × 3.94 in — accommodates standard enclosure formats across security, life-safety, and access control infrastructure. Certified to UL 1989.
Typical Applications
The CBL4-6 is designed for float standby and light cyclic discharge duty in systems requiring compact, sealed backup power. Rated at 4Ah (C20) at 6V, the battery is suited to moderate standby loads and short discharge durations. Typical deployment includes uninterruptible power supplies (UPS), electric power systems (EPS), emergency lighting equipment, exit sign backup units, fire detection and alarm panels, security alarm systems, access control systems, electric gate operators, communication power supplies, DC control systems, medical monitoring equipment, and telecommunications infrastructure. The CBL4-6 is commonly used as a replacement 6V 4Ah SLA and AGM battery in security systems, emergency lighting equipment, access control systems, and UPS installations.
UL 1989 Certification
The CBL4-6 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 CBL4-6 6V 4Ah 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.

This is a funny store actually, I wanted to decorate a little so I bought a string of LED lights and I needed a 12V battery for power. I have charged it only once in the past week and they are running smoothly no cuts so far. Definitely a high-quality AGM battery. oh and shipping time was under a week and it was free. Will definitely recommend it to my friends. Thanks again
