True Load Testing Makes This One of the Best
By Amazon Customer
One of the problems with most (less-expensive) battery testers is that they only check for voltage remaining in a battery. Even an 80% used battery can show nearly full rated voltage, and it is only when a load is placed on the battery that a true assessment is possible. Our college AV department goes through lots of batteries for DVD remotes, wireless mics, etc., and the other cheaper testers were not providing accurate results. This unit (and its big brother model) use an electronic circuit to test the battery for approximately two seconds under an electrical load. While doing this, the LED's light back and forth, and then the tested capacity is displayed. I highly recommend this unit for consumers and professionals alike. it is easy to use and very accurate. If you use a lot of button cell batteries, or lithium batteries (either AA or specialized camera/camcorder lithium ion batteries), you should probably purchase the larger ZTS MBT-1. The MBT-1 costs over twice as much and is larger in size, but consider that model for most versatility.

comparison of mini and full-size battery testers
By R. M. Sills
I first bought a ZTS Mini Multi-Battery Tester (MINI-MBT), but later decided that it would be useful to have the larger and more expensive ZTS Multi-Battery Tester (MBT-1). This review might help if you're trying to decide which one to get.
Both testers are excellent at performing their jobs. The reason that I eventually found the mini-tester inadequate is that I have quite a few devices whose batteries can't be tested by this device (but can be tested by the larger MBT-1):
- 3v lithium coin (2016, 2032, etc.)
- 1.5v button cell (S76, A76, 357, LR44, etc.)
The mini-tester works on four classes of batteries, while the full-size tester works on ten classes (several of which I've never seen). The full-size version handles every battery-operated device I have except for a few devices that use oddball tiny button cells (392=SR41, 386=SR43, 389=SR54) -- for instance, a meat thermometer and a fever thermometer.
Other than the set of batteries that can be handled, there are a few small differences between the two testers. The mini-tester has an "on" switch and auto-off; the large tester has no switch at all. Both testers have a row of LEDs that indicate the battery state -- five on the mini and six on the full-size (with an additional LED for 10% battery life). The mini-tester uses four AAA batteries, while the full-size tester uses four AA batteries; both units have a self-tester to let you know when these batteries need to be replaced.
The most obvious difference between the two is sheer size -- the mini-tester similar to a pack of cards, the full-size tester more like a hefty book with narrow pages.

Saves me money!
By Lesley Kennedy
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 were dead. Before I had this tester, I would replace all the batteries. Now I can replace only the dead ones. It is great!
