Description
CBL35-12 | 12V 35Ah Sealed Lead Acid Battery | 420Wh | Group U1 | T6 Terminal | 24.7 lbs (11.2 kg) | Lead Calcium Alloy | UL 1989 Certified
The Canbat 12V 35Ah SLA battery is a valve-regulated sealed lead acid (VRLA) AGM battery designed for mobility equipment, standby power systems, and light-duty off-grid applications requiring high reserve capacity and extended 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 and cyclic performance across a 20+ year design floating life at 20°C. Rated at 35Ah and 420Wh with a charge temperature range extending to -4°F (-20°C), the CBL35-12 is well-suited to year-round Canadian operation across a wide range of mobility equipment, standby power systems, and off-grid applications. Certified to UL 1989.
Typical Applications
The CBL35-12 12V 35Ah SLA battery is designed for mobility, standby power, and light-duty off-grid applications where high reserve capacity and extended runtime are required. Rated at 35Ah (C20) at 12V and built to Group U1 dimensions, this 12V 35Ah SLA battery serves a broad range of applications across mobility, commercial standby, and outdoor power markets. Typical deployment includes mobility scooters, electric wheelchairs, power wheelchairs, medical mobility equipment, UPS backup power systems, fire alarm systems, emergency lighting systems, security alarm systems, lawn tractors, solar lighting systems, small off-grid power systems, electric power systems (EPS), and DC control systems. The CBL35-12 is commonly used as a replacement 12V 35Ah SLA and AGM battery in mobility scooters, electric wheelchairs, medical equipment, lawn tractors, UPS systems, fire alarm systems, and emergency lighting installations.
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 CBL35-12 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 CBL35-12 12V 35Ah 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.

Mon quadriporteur Shoprider Spirit GK10 avait besoin de nouvelles batteries depuis longtemps, et je ne savais pas comment les remplacer ni lesquelles choisir. Mais Canbat a eu la patience de répondre à toutes mes questions et m’a conseillé cette batterie qui fonctionne à merveille depuis 2 mois. J’achèterai à présent toutes mes batteries chez Canbat!

We’ve purchased 40 of these for our project to replace Rolls battery S12-33AGM and we are very happy with the quality, despite the Canbat one having a much better price. Customer service has also been super. Thanks and I look forward to buying more in the future.
