ZTS Multi-Battery Testers™ (MBTs) are trusted and relied on by people who use batteries in critical applications, such as the U.S. military, medical device manufacturers, underwater diving, life support, emergency backup power, and more. These folks use ZTS testers to provide the assurance that their batteries will perform when needed.

You can have this affordable technology in your home and office as well. The average U.S. household has more than 20 battery operated devices. Whether you're testing for safety - such as smoke detectors, flashlights, baby monitors - or simply sorting the batteries in your kitchen drawer, a ZTS MBT will give you fast and accurate test results.

Every ZTS MBT is designed and made in America. Every tester is 100% quality and endurance tested to ensure accuracy and reliability. ZTS MBTs provide a fully automatic pulse load test to determine state of charge (SOC) or state of power. The pulse load test simulates real power demand and measures battery performance, not just voltage.

We are a family owned business, and our customer service is second to none. Your complete satisfaction is our goal and highest priority. Once you use a ZTS MBT, you'll wonder how you did without.

Order your's today, we know you'll love it.
"Fantastic quality product! Easy to use and accurate. Now I can finally throw out all my cheap testers, which never really worked!" U.K.
"Saves me money! This battery tester has already paid for itself. If a toy (or electronic gadget) is running slow, I remove and test all the batteries. Each time I found that some of the batteries still had 80% life in them, while others we dead. Before I had this tester, I would replace all the batteries. Now I can replace only the dead ones. It is great!" CA
