CLC150-12FT  |  12V 150Ah Lead Carbon Front Terminal Battery  |  1,800Wh  |  T11 (M8 Threaded Insert)  |  105.8 lbs (48.0 kg)  |  Pure Lead Carbon  |  UL 1989 Certified

The Canbat 12V 150Ah Lead Carbon Front Terminal Battery is a pure lead carbon VRLA battery engineered for rack-mounted and cabinet-installed stationary energy-storage systems that require front-access terminal connections, partial-state-of-charge tolerance, and rapid recharge between discharge events. Rated at 150Ah (C10) and 1,800Wh with 2,500+ cycles at 50% depth of discharge, support for deeper discharge profiles up to 80% DoD where system design allows, and a 20+ year design floating life at 20°C, the CLC150-12FT delivers premium partial-state-of-charge energy-storage performance for telecom base stations, communication power systems, 19-inch and 23-inch telecom power systems, remote power cabinets, and hybrid inverter and genset systems. Carbon added to the negative electrode helps reduce sulfation under partial-state-of-charge operation — a common failure mode of standard AGM batteries in daily-cycling and remote-power applications. Certified to UL 1989.

Typical Applications

The CLC150-12FT 12V 150Ah Lead Carbon Front Terminal Battery is designed for rack-mounted and cabinet-installed stationary energy-storage applications where front-access terminal connections, partial-state-of-charge tolerance, and fast recharge are required. This 150Ah front terminal battery is suited to telecom base stations, microwave stations, communication power systems, 19-inch and 23-inch telecom power systems where fitment is verified, remote power and outdoor cabinet installations, UPS backup systems with rack-mount requirements, critical UPS backup applications, utility substations and switchgear control power, and industrial partial-state-of-charge cycling applications. It is also suitable for off-grid energy storage installations where front-terminal cabinet access is preferred.

For telecom and remote infrastructure systems, this 150Ah front terminal battery provides more reserve runtime than the CLC100-12FT while avoiding the larger footprint of the CLC210-12FT — making it the mid-tier front terminal option in the Canbat CLC lineup. The CLC150-12FT also serves as a 12V 150Ah lead carbon battery option for rack and cabinet systems where front-access terminals are required. Four 12V batteries can be configured as a 48V string where system design requires it. Commonly used as a replacement front-access lead carbon battery in telecom infrastructure, remote power sites, rack-mounted energy storage systems, and engineered stationary PSoC applications requiring 150Ah capacity.

UL 1989 Certification

UL 1989 certification provides third-party verification of battery safety and performance requirements for sealed lead acid batteries. The CLC150-12FT is certified to UL 1989, the Underwriters Laboratories standard covering electrical performance, mechanical integrity, and safety requirements including overcharge tolerance and short circuit protection. As a valve-regulated sealed lead acid battery, the CLC150-12FT does not carry the thermal runaway profile associated with lithium-ion energy storage systems and does not require a Battery Management System for cell-level protection — simplifying installation and reducing system complexity for indoor, rack-mounted, and remote-site energy-storage applications. 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, including the CLC lead carbon series.

Front Terminal Design & Carbon-Enhanced Plate Technology

The CLC150-12FT 12V 150Ah Lead Carbon Front Terminal Battery features a slim front-terminal case — 4.92 inches wide — designed for rack-style and cabinet installations, including 19-inch and 23-inch telecom power systems where dimensions, shelf rating, and cable clearance are verified. Front-access M8 terminals allow all cable connections, voltage checks, torque checks, and service work to be performed from the front of the rack — eliminating the need for overhead clearance, simplifying cable management, and reducing service time during inspection and battery replacement in tight cabinet environments. An integrated carry handle supports handling and positioning during installation.

Carbon added to the negative electrode improves charge acceptance and helps reduce sulfation under partial-state-of-charge conditions — a common failure mode of standard AGM batteries in telecom, solar, and remote-power applications where batteries are rarely recharged to 100% daily. The carbon additive acts as a supercapacitor layer within the negative plate, improving conductivity and helping maintain plate integrity under the irregular recharge patterns common in telecom infrastructure and renewable energy systems.

Carbon conductivity also improves charge acceptance, helping the CLC150-12FT recover efficiently between discharge events — a critical operational advantage for telecom sites recharging between outages, off-grid installations with variable solar availability, and hybrid genset systems with limited run time.

The sealed valve-regulated design provides non-spillable, maintenance-free operation with no watering requirements. The durable ABS container is suited to rack-mounted telecom, remote power, and stationary energy-storage applications. Canbat lead carbon batteries offer up to 24-month storage capability under proper conditions, with recharge intervals depending on storage temperature and state of charge.

PSoC Performance & Cycle Life

The CLC150-12FT 12V 150Ah Lead Carbon Front Terminal Battery delivers 2,500+ cycles at 50% depth of discharge — strong partial-state-of-charge cycling performance for a front terminal VRLA battery in rack-mounted energy-storage applications. Cycle life is dependent on depth of discharge, charging profile, operating temperature, and maintenance practices. Shallower discharge depths deliver substantially more cycles than operation at full depth of discharge.

Compared with standard AGM batteries, the CLC150-12FT is better suited to deeper cycling and partial-state-of-charge operation. In properly designed energy-storage systems, lead carbon technology can support deeper discharge profiles, up to 80% DoD where system design allows, while maintaining stronger cycle performance than conventional AGM batteries under demanding partial-state-of-charge conditions.

For telecom and remote infrastructure applications where the battery primarily operates on float standby and is discharged only during outages, the CLC150-12FT is rated for a 20+ year design floating life at 20°C. Four 12V CLC150-12FT batteries can be configured in series as a 48V 150Ah battery string where system design requires it.
