What Kung Long Batteries does
Kung Long Batteries Industrial Co., Ltd. (廣隆光電科技股份有限公司) is a Taiwan-based battery manufacturer founded in 1990 and listed on the Taiwan Stock Exchange (TWSE: 1537). The company designs and produces VRLA (Valve Regulated Lead Acid) batteries and lithium battery solutions across more than twenty product sub-series, including AGM, Gel, Pure Lead, High Rate, Extreme High Rate, Long Life, High Temperature, and 2-volt deep cycle variants, plus lithium sub-systems for UPS, telecom, and residential energy storage. Application focus spans data centers and UPS, telecommunications (indoor and outdoor base stations), renewable energy storage, electric mobility (e-bikes, forklifts, golf carts, home medical devices), automotive and motorcycle starting, and marine/RV dual-purpose use. The company operates three modern production bases split between Taiwan (Nantou headquarters) and Vietnam (wholly-owned subsidiary LE LONG / 利隆), and serves buyers across seven global regions via direct sales from Taiwan headquarters and an international sales division.
The business model is hardware sales of batteries under a quoted-price model with no public pricing. Go-to-market is sales-led: direct sales in Taiwan and Vietnam, complemented by overseas sales offices, a corporate website with product catalog and inquiry cart, and participation in industry trade shows such as Data Center Asia 2026. Customer segments are diversified across use cases (data center/UPS, telecom, renewable energy, mobility, automotive, marine/RV, security) rather than concentrated in a single vertical. The company differentiates through its listing plus bonded-factory status (Taiwan's only listed lead-acid battery manufacturer), multi-site production diversification, and a 30-plus-year operating track record. Recent 2025 disclosures include rankings in CRIF Taiwan's TOP 5000 (812th overall, 4th in battery industry) and 2026 award/trade-show activity, while financials show revenue declining approximately 18.5% year-over-year in the most recent reporting period.
