Some would say that building a battery is simple. Well, on the surface that may be true, but when you peel back the layers of creating a power solution that works efficiently across varying power demands, safely in a myriad of environments, and dependably in real-world applications, it’s a different story.

At Totex, our story can be seen in the thousands of products we have produced and in the trusted relationships we have forged with our customers. Our commitment to quality and innovation can be recognized in everything we do.

We have been solving challenges and creating real-world solutions for over 35 years. Solutions for medical, industrial, consumer, and military applications is where we live.

We bring a complete solution that starts with experienced engineering, elegant design, comprehensive testing, cutting-edge manufacturing, and global logistics. That is our daily mission.

We don’t just follow the industry standards, we set them.
