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.
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.]
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.
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.
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.
