CBAK Energy Technology's Dalian CBAK Power Battery Completes Product Portfolio Upgrade And Begins Operating A New Production Line For The Model 40135 Battery

CBAK Energy Technology, Inc. (NASDAQ:CBAT) ("CBAK Energy" or the "Company"), a leading manufacturer of lithium-ion and sodium-ion batteries and integrated electric energy solutions in China, today announced that its wholly owned subsidiary, Dalian CBAK Power Battery Co., Ltd. ("Dalian CBAK"), has completed its product portfolio upgrade and commenced operation of a new production line for its Model 40135 battery. The Model 40135 features a larger size and higher capacity compared to the Company's current best-selling and flagship product, Model 32140.

Starting in 2025, Dalian CBAK has been investing in the establishment of this new production line to upgrade its core product from the Model 26650, which was originally developed in 2006. As part of this transition, major customers of Dalian CBAK are currently testing, validating, and migrating to the new Model 40135, which has temporarily impacted sales performance during the transition period.

With the launch of the new production line, Dalian CBAK has achieved an initial daily production capacity of approximately 20,000 cells and, within just one month of operation, has already delivered around 500,000 cells, generating approximately US$2 million in revenue. The Company expects production to ramp up to about 100,000 cells per day by the end of this year. Despite operating at limited capacity for only a month, Dalian CBAK has already received orders totaling approximately 1.2 million cells pending delivery, representing an estimated US$5 million in revenue and demonstrating the strong market demand for the new model.

"CBAK Energy's product portfolio now includes small cylindrical cell models such as 26650/26700, and large cylindrical models including 32140/40135," said Zhiguang Hu, CEO of CBAK Energy. "We remain committed to continuous R&D investment and to introducing new cell models that meet evolving market needs. The strong inflow of orders in just a month days has strengthened our confidence in the Model 40135, and we expect Dalian CBAK's sales performance to reach new highs soon. We also look forward to completing the first phase of the expansion at our Nanjing facility and will share further updates with the market in due course."
