At Cen Tech® Battery Charger, we specialize in developing and manufacturing high-quality battery chargers and power solutions. Our team has over 20 years of experience designing, engineering and assembling chargers that revive and repower automotive, marine, deep cycle, golf cart, and commercial batteries.
Our Story

Cen Tech® Battery Charger was founded in 2001 by a group of engineers and product designers who shared a passion for creating reliable, affordable battery charging equipment. Our founders had worked extensively in the power systems industry and saw an opportunity to develop battery chargers that combined advanced technology with ease-of-use.
In those early days, we operated out of a small warehouse, tinkering away on prototypes and testing different charging circuits. Our first product was a simple automatic battery charger for 12V lead-acid batteries. We marketed it to automotive shops and received valuable feedback from technicians that allowed us to refine the design.
Encouraged by the positive response, we expanded our product line to include chargers for other battery types and higher charge rates. We built partnerships with major battery manufacturers to ensure our chargers adhered to their technical specifications.
Over the years, Cen Tech® Battery Charger has grown from those humble beginnings into one of the most recognized brands in battery charging systems. But we’ve never forgotten our roots. Our engineering team still actively gathers input from end-users to create chargers that are adaptable, safe, and easy to operate.
Today, we provide battery charging solutions for consumers, businesses, and industrial applications. Our state-of-the-art manufacturing facility produces thousands of units per year, without sacrificing the quality control and attention to detail that set our chargers apart.
