ZTS Multi-Battery Tester MBT-1 handheld pulse-load tester with LED percent readout

The ZTS Multi-Battery Tester (MBT-1) is a compact, microprocessor-controlled tester that uses a patented pulse load test to display remaining capacity for over 30 battery types.

The MBT-1 is a handheld, made-in-USA instrument designed to quickly show state-of-charge or state-of-power for primary and rechargeable cells. It combines one-touch testing with an LED bar readout so you can spot weak, mismatched, or failing batteries without guessing. No user settings or switches are required — just place the cell and read the percentage result after the automatic test cycle.

Which battery chemistries and sizes will this tester handle?

The MBT-1 covers a broad range of common consumer and specialty batteries, from cylindrical rechargeables to coin cells and 9V bricks. Battery type labels are printed beside each contact so you can match the cell quickly before testing.

• Rechargeables: NiMH/NiCd (AA, AAA, C, D), 3.6V Li‑Ion (RCR123A, 18500, 17650, 18650)
• Primary alkaline & lithium: AA, AAA, C, D, N, A23, L91/L92
• Coin and button cells: CR2032, CR2025, CR1632, CR1616, LR44, 357 and many others
• Special voltages: 3V cylindrical (CR123, CR2), 6V 28-series, 9V, 12V A23

How does the pulse load test improve result accuracy?

Instead of a simple open-circuit voltage check, the MBT-1 applies a brief, controlled load and measures the battery’s response with a microprocessor. That reveals how the cell performs under realistic demand, helping distinguish a low-but-serviceable battery from one that will fail in use.

• Patented pulse load method for realistic performance measurement
• Microprocessor-controlled timing and analysis for consistent results
• LED bar displays percent remaining after the test cycle
• Automatic operation eliminates manual adjustments and user error

What practical benefits will I notice using this tester?

You’ll save time and money by identifying weak or mismatched batteries before they cause devices to underperform. The MBT-1 makes cell matching easy for packs, hobby builds, and battery management tasks, and its clear readout reduces uncertainty when replacing batteries.

• Quickly find failing or low-capacity cells to avoid device downtime
• Match cells by remaining capacity for safer, balanced packs
• Useful for workshops, hobbyists, technicians, and home use
• Compact footprint with a side-mounted probe that stores neatly

Who is this for? The ZTS MBT-1 is built for anyone who relies on batteries regularly: technicians verifying supply stock, hobbyists assembling battery packs, photographers, security and medical equipment managers checking spares, and homeowners who want reliable household device power. It’s especially helpful where accurate, repeatable, and quick battery assessments prevent unexpected failures. The unit runs on four AA batteries (not included) and is made in the U.S.A., offering a portable, no-fuss solution for single-cell diagnostics and cell-matching tasks.
