The CALB L173F280A stands as a premium benchmark in the 280Ah prismatic cell market. Engineered for extreme longevity, this model offers a staggering 9,000 cycle life, effectively allowing users to “install it once and forget it for a decade” in professional ESS or high-end EV conversion projects.
Industry-Leading Longevity: With a chemistry rated for 9,000 cycles, the CALB L173F280A significantly outperforms standard 280Ah cells, maximizing the long-term ROI of your battery system.
Ultra-Low Internal Resistance: Maintains a typical IR of approximately 0.18 mΩ, ensuring cooler operation under high loads and superior energy efficiency compared to competitors.
Precision Industrial Specs: Features a standard footprint (174.4 x 71.4 x 207 mm) and a specific industrial pre-tightening pressure requirement of 300 ± 20 kgf for optimal structural stability and cell health.
Grade A Traceability: Every cell is sourced directly from the production line with original, intact QR codes, guaranteeing authentic Tier 1 quality and data transparency.
Produced to Order (No Aged Batches): We strictly follow a “Produced to Order” policy to eliminate the risks of chemical degradation found in aged inventory. Every CALB L173F280A we supply is freshly manufactured from the latest production batches.
Bespoke Flexible Connection Solutions: For high-voltage or 48V systems, we provide customized flexible copper busbars. These are essential to safely accommodate the micro-expansion of cells over their 9,000-cycle lifespan, preventing stress on the terminals.
Hassle-Free DDP Logistics: We provide comprehensive DDP (Delivered Duty Paid) shipping options to major global regions. DLCPO manages the entire logistics chain, including customs clearance and import duties, delivering directly to your door with zero hidden fees.
Professional Cell Matching: Every order undergoes rigorous testing at our facility. We provide sets matched for Voltage and Internal Resistance (IR) to ensure your battery bank remains perfectly balanced from the very first day.
A: The CALB L173F280A has a precision body length of 174.4 ± 0.3 mm, a thickness of 71.4 ± 0.3 mm, and a total height (including terminals) of 207 ± 0.40 mm. The body height without terminals is 204.45 ± 0.50 mm.
A: To achieve the rated 9,000 cycles, the CALB L173F280A requires a specific pre-tightening force of 300 ± 20 kgf during assembly. This industrial-grade compression ensures internal contact stability and prevents delamination over its decade-long service life.
A: Yes. We offer DDP (Delivered Duty Paid) services, which means the price we quote includes all international freight, insurance, and local import taxes. You simply receive the freshly produced CALB L173F280A cells at your location without dealing with customs brokers.

The Ultimate ESS Solution:
DIY Powerwalls: Connect 16 cells in series for a 48V 280Ah (14.3kWh) home battery system.
Solar Energy Storage: Store excess solar power for night use. 9000 cycles means 15+ years of daily use.
Off-Grid Cabins: Reliable massive energy storage for remote locations.
Electric Boats: High capacity and long life for marine propulsion banks.
Compression Required: To achieve the rated 9000 cycles, cells should be compressed at 12-18 PSI (approx 300kgf).
Terminal Torque: Use a torque wrench (6-8 Nm) for busbar connections. Do not overtighten.
Safety Valve: Ensure the vent valve is not obstructed.
