Review: 5 years on, works like a charm. Great tool! - What a great tool: simple, functional, always "just works". I've had it now almost 5 years, same model (t333, listed now as a "desertcart choice") and I'd bought it at same price shown now. That's sweet. If you need a battery tester, buy it, as it handles so many types-- even button ones, and is so easy. (Indeed, it takes one AAA battery, which I'd totally forgotten about until finding this listing again. I've not changed it since purchase! Of course, it may depend on how often you're testing: I might test a couple a month. But it's lasting.)
Review: Great Product & Good Value - This is a great little battery checker. You can find lower-priced products, but the Tenergy is worth the few extra dollars. It’s versatile in that you can check all of the common battery sizes found in a home. You can also assess disposable and rechargeable batteries. The cells snap into their slot, assuring good connections for an accurate read. The unit even utilizes its own power source (battery), so it doesn’t have to draw power from the battery you’re checking, contributing to accuracy. I’m very satisfied with the product and highly recommend it.
