Who are Kirkland batteries made by?
Kirkland batteries are not explicitly mentioned in the provided documentation, which focuses exclusively on CALB (China Aviation Lithium Battery), a state-owned enterprise specializing in lithium-ion batteries. CALB, formerly known as CATL subsidiary, produces high-performance LiFePO4 cells (3.2V 100Ah–280Ah) for EVs, energy storage, and industrial equipment. The company operates five production bases in China and supplies standardized cells for applications like golf carts, RVs, and solar systems. While Kirkland-branded batteries may use CALB cells in some configurations, no direct manufacturing link is confirmed here.
What products does CALB manufacture?
CALB specializes in lithium iron phosphate (LiFePO4) cells for electric vehicles and energy storage. Their 3.2V prismatic cells (100Ah–280Ah) feature cycle lives exceeding 4,000 cycles at 80% DoD, with operating temperatures spanning -20°C–55°C.
CALB’s product line targets high-power mobility and stationary storage. For example, their 230Ah cell delivers 736Wh at 3.2V, ideal for golf carts requiring 72V systems (24S configurations). Pro Tip: Always balance CALB cells within ±20mV when building custom packs—voltage mismatches above 50mV accelerate capacity fade. A 72V 280Ah pack using CALB cells provides 8.96kWh, sufficient for 120–150 km in mid-sized electric trucks.

Where are CALB batteries produced?
CALB operates five manufacturing hubs across China: Changzhou (core R&D), Luoyang, Xiamen, Chengdu, and Wuhan. The Xiamen facility alone produces 14GWh annually of LiFePO4 and NMC cells for global markets.
These ISO-certified plants employ automated electrode stacking and vacuum sealing to minimize moisture ingress. CALB’s Chengdu base focuses on EV batteries, while Wuhan specializes in energy storage systems. For context, their 100Ah cells undergo 23 quality checks, including ultrasonic welding inspections and 48-hour formation cycling. Practically speaking, this standardization enables reliable 72V pack assembly—24 CALB 3.2V 100Ah cells in series typically achieve ±0.5% voltage consistency post-balancing.
