This battery checker does not perform as advertised. The problem is that there are supposed to be 18 gradients of battery life, with 1-5 for POOR, 6-10 for FAIR and 11-18 for GOOD. But all these levels appear to be mainly for eyewash, since this tester will show most used batteries to have a full 18 level of GOOD. For anyone wanting a simple "go or no go" tester, perhaps this will do the job. But if you expect true sensitivity to accurately check batteries having various remaining charges, then this item will probably disappoint you.

Since it cost $18.99 with shipping, I decided to request return of the tester to the vendor, Battery Superstore. Aside from not being sensitive as advertised, it would not give readings for 2 of 12 battery sizes advertised. After receiving my request, the customer service department at Battery Superstore wrote back stating that although they were sorry I did not like the charger, they would charge me a 10% restocking fee plus the $6.00 shipping charge, and I would pay the return shipping. I wrote once more to question the charges for returning defective merchandise, and they responded that the charger was good, but they would kindly waive the $1.20 restocking fee. Even with this. however, I would still be losing most of my money on the unlucky purchase, so I decided to keep the tester. I will be very careful not to purchase from the Battery Superstore in the future.

I am forever trying to figure out if my kids toys don't work because the batteries are dead or the toy is dead. This meter is fantastic! It doesn't just give a readout of good or dead, it shows you how much is left in the battery on an easy to read LCD display. I realize it costs a little more, but the extra information it provides was worth the extra money. And as a bonus, I don't have to teach my wife and kids how to use my voltmeter -- they can easily use this!

I was too generous - Deserves only TWO STARS

After gone from using this battery tester quite often (when first purchased) to using it less frequently, I have changed my assessment. Basically, having not fresh in my mind where the true scale reads, I am guessing the battery condition. In addition, brand new batteries read halfway on the "good" scale. Taking into account this, and the scale discrepancies noted in my original review, there is very little the tester can tell you about a battery's charge. As others have pointed out, it is indeed just a Go / No-Go tester. I always end up using my other tester instead (the ZTS Mini-MBT) Which begs the question, "Of what use is this tester?" Answer: Marginally better than nothing. Amazon.com's review editor feature won't allow me to change the number of stars from four to two - bad feature. For continuity, my original review follows (in brackets.)

[For the most part, I have to echo the other reviews of this battery checker. A good buy; a good instrument. However, I have issue with the scale on the device. When it reads 'Weak' the batteries are indeed 'Poor'. In fact, a mid-scale reading of 'Weak' actually means "ready for disposal". I thought at first it was just a difference in semantics so I removed my batteries that read 'Weak' from the tester and put them into a Mini-Maglite flashlight. An almost invisible, pale orange glow was all that was produced - not a functionable battery at all. Once you realize where the true line between a good battery and a weak one actually is on the tester's scale, then this tester becomes a 5-star instrument and gives good, repeatable results.]

I am an electrical engineer and I say this item is a waste of money. It is not a battery checker, it is simply a voltmeter. A real battery checker will test a battery under load. Measurement of no-load battery voltage is of little use when determining remaining life of a battery. Batteries that showed "GOOD" on this item under no load, read "WEAK" or "POOR" when I placed a 100 Ohm resistor across them. That resistor provides a modest 15 mA load for a 1.5 V battery. To place this current value in perspective, a typical LED requires about that much current. This item only draws about 0.02 mA from the battery being tested.

If you want a voltmeter, purchase a cheap digital multi meter (DMM) for the same money. If you want a battery checker, purchase something else like the Amprobe BAT-250.

Construction wise it is okay.
Layout, design, ease of use is great.
Simple to use and looks like it would last a long time.

I do not have it in front of me at the moment (I'm at work).
There are several LCD bars ranging from dead to poor, to weak, to good.
(Again I believe)...Each range has about 4 or 5 bars within a group or 16 to 20 bars total.

Problem is with a fully charged "rechargable" the checker shows or highlight in the middle of the 'good'. I also tested a battery that had been in a wall clock for over a year (clock was dead stopped) it read at top end of the weak or about 2-3 marks below the fully charged NiMH just now charged.

I suspect a brand new alkaline may be able to get a little higher than middle of the 'good' range.

Bottom line:
If you are using rechargables, do not buy the T-333.
If you are using alkaline, you will be able to detect brand new and not brand new. There may be a subtle difference between used and dead.

The best tester for rechargable batteries which I got the same day as T-333 is the ZTS MINI BATTERY TESTER.

The best tester/charger which I also got the same day is the La Crosse BC900.

Also the following is what I've read, have not verified myself yet.
There are two types of NiMH batteries.

Very high capacity around 2600 maH.
These slowly lose there charge on the self.

The other type is pre-charged around 2000 maH
These hold there charge over a year self life.

Also Sanya enevelope or something like that are the ones to get.
