ZTS Multi-Battery Tester MBT-1 — handheld pulse-load battery tester with LED percentage readout

The ZTS Multi-Battery Tester (MBT-1) is a handheld, microprocessor‑controlled meter that quickly shows remaining battery capacity for over 30 battery types using a patented pulse‑load test.

Whether you maintain tools, cameras, hearing devices, smoke alarms, or a drawer full of miscellaneous batteries, the MBT-1 gives a clear, percentage‑style LED readout so you can decide which cells to keep, recycle, or replace. Designed and built in the U.S.A., this compact tester requires no settings or switches — insert the battery, and the tester runs an automatic diagnostic. It supports common primary and rechargeable chemistries, from coin and button cells to 18650s and 9V blocks.

How does the MBT-1 determine a battery’s remaining capacity?

The MBT-1 uses a patented pulse‑load technique combined with microprocessor analysis to simulate real device demands and estimate usable capacity. The result is shown on an LED bar graph as a percentage of remaining power after an automatic test cycle.

• Pulse‑load mimics real-world current draw for more realistic assessment
• Microprocessor interprets voltage and load response for accuracy
• LED bar displays a clear percentage-style reading—no decoding required
• Automatic cycle: insert battery and read result, no switches needed

Which battery types and sizes can this tester handle?

MBT-1 supports more than 30 popular battery formats used in consumer and specialty devices. It tests primary and rechargeable chemistries across multiple voltages and sizes so you can manage everything from coin cells to cylindrical Li‑Ion cells.

• AA, AAA, C, D, N — alkaline and NiMH/NiCd rechargeables
• 9V and 12V (A23) alkaline, plus 6V '28' series packs
• Coin/button cells: CR2032, CR2025, LR44, 357 and many more
• Li‑Ion cylindrical: 18650, 17650, 18500 and CR123/CR2 types

What makes the MBT-1 practical for everyday use and battery management?

The unit is engineered for simplicity and repeated use: there are no menus or switches, results are easy to interpret, and the negative test probe stores neatly in a side seam. It’s a solid tool for matching cells, validating inventory, and reducing device failures caused by weak batteries.

• Plug‑and‑test operation—saves time when checking many cells
• Compact, handheld design with probe storage for portability
• Useful for cell matching when assembling multi‑cell packs or replacing batteries
• Powered by four AA batteries (not included) for field use

How accurate and reliable is the MBT-1 for technical tasks?

The MBT-1’s patented testing method is intended to give a high‑accuracy snapshot of state of charge and usable power under load, suitable for routine maintenance and comparative testing. While not a laboratory instrument, it helps identify weak or failing cells that would perform poorly in real devices.

• Patented pulse‑load testing offers more realistic results than simple open‑circuit voltage checks
• Microprocessor control reduces variability between tests
• Clear labeling next to contacts reduces mis-testing of battery types
• Made in U.S.A., built for regular consumer and prosumer use

Who is this for? The ZTS MBT-1 suits anyone who regularly uses or stores batteries: hobbyists, photographers, technicians, educators, emergency-prep organizers, and households seeking to avoid device failures. It’s especially helpful for people who need to match battery cells for packs, confirm charge before critical use, or keep a tidy, tested battery stockpile.
