Watch out

  • ZTS sells several testers (MBT-1, MINI-MBT, MINI-9RL); listings often mix them up. Check the model name on the front label.
  • An MBT-LA2 or MINI-MBT9R listing is the older or different model, not the MINI-MBT.

Why people pick it

  • Pulse-load testing measures performance under load rather than just open-circuit voltage, which better identifies weak or failing cells, per ZTS
  • Covers more than 15 battery types including 3 V lithium CR123/CR2 and 3.6 V Li-Ion cylindrical cells that ordinary household testers skip
  • No switches or settings: drop the battery on the labeled contacts and read the LED bar, with results in about 2 seconds
  • Palm-size (4 x 2.5 x 0.75 in) with a self-storing probe, made in the U.S.A.

Know before you buy

  • Does not test 9 V NiMH or 9 V Li-Ion rechargeable types; those need the MINI-9RL, and coin/button cells need the MBT-1
  • Powered by 4 AAA internal batteries that are not included and must be kept fresh
  • LED bar gives percentage bands, not a numeric state-of-health readout
