ZTS Multi-Battery Tester MBT-1 — LED % Display, Patented Pulse-Load Accuracy for AA–9V & Coin Cells

The ZTS Multi-Battery Tester (MBT-1) is a handheld, microprocessor-controlled device that quickly measures remaining capacity across more than 30 battery types using a patented pulse load test.

Designed and assembled in the U.S.A., the MBT-1 removes guesswork from battery management by delivering an easy, automatic percentage readout on a clear LED bar display. There are no switches or complicated menus — insert the battery or attach the probe and the tester runs a full test cycle, showing the state of charge or state of power for common primary and rechargeable cells.

How does the MBT-1 show a battery’s health?

The MBT-1 runs a patented pulse load test that simulates real-world discharge conditions, then microprocessor logic calculates remaining capacity and displays it as a percent on the LED bar. This gives a practical picture of how a battery will perform under load, not just its open-circuit voltage.

• Patented pulse load algorithm for realistic results
• LED bar displays percentage of remaining capacity
• Microprocessor control ensures repeatable, automatic cycles
• No manual calibration or settings required

Which battery types can I test with this tool?

The MBT-1 supports a broad range of cells — from tiny coin cells to 9V bricks and common cylindrical rechargeables — making it a single tool for household, hobbyist, and professional battery checks. Battery contacts are labeled next to each test point for fast identification.

• Rechargeables: NiMH/NiCd AA, AAA, C, D and Li-Ion 3.6V cylindrical sizes
• Primary: alkaline AA/AAA/C/D/N, 12V A23, 9V, and 6V 28-series
• Coin/button cells: CR-series, LR-series, and other common button types
• Probe lead stores in the unit seam for testing non-standard shapes

What makes this tester easy to use for everyday needs?

There are no switches, settings or user menus to navigate: place the cell on the labeled contact or clip the negative probe and the MBT-1 completes the test automatically. Results are presented simply as a percentage so you can decide whether to keep, recycle, or match cells.

• Fully automatic test cycle—insert and read results
• Clear LED bar simplifies pass/fail and state-of-charge judgments
• Compact handheld format with onboard probe storage
• Uses 4 AA batteries (not included) for portable field use

How accurate and reliable are the readings?

Built around a high-accuracy pulse load test and microprocessor analysis, the MBT-1 provides consistent, repeatable measurements that reflect how cells behave under load rather than just open-circuit voltage. It’s well-suited for cell matching and tracking battery health over time.

• Pulse load testing yields practical, load-relevant metrics
• Microprocessor control reduces variability between tests
• Ideal for matching cells in multi-cell devices and inventory checks
• Manufactured in the U.S.A. with labeled contacts for clarity

Who is this for? The ZTS MBT-1 is aimed at technicians, electronics hobbyists, photographers, makers, and anyone who needs a dependable, portable way to assess battery capacity quickly. If you maintain devices that rely on a variety of battery formats or need to match cells for multi-cell packs, this tester streamlines that work without complex setup or interpretation.
