What a great tool: simple, functional, always "just works". I've had it now almost 5 years, same model (t333, listed now as a "Amazon 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.)

J'ai un testeur de courant qui permet de vérifier le niveau des batteries. Par contre, parce que je ne l'utilise que rarement, je me demande à chaque fois si je l'utilise correctement. De plus, je dois connecter le fils rouge & noir à chaque fois, mettre le bon réglage et utiliser les pointes des contacts correctement. Il y a quelques jours, je me suis dit qu'il devait exister une solution plus simple pour ce problème simple. J'ai commandé cet appareil et viens juste de tester une dizaine de batteries. C'est fou comme c'est fabuler à utiliser. Pas d'opération "complexe", juste à mettre la batterie dans le bon emplacement et l'affichage du niveau de charge apparaît. La vie sera plus facile dorénavant :)

Es uno de los articulos comprados en Amazon que más me ha gustado. Es muy ligero, y hace mediciones de prácticamente todos los tamaños de baterías.

Especially useful if you use smart home devices such as door/window sensor, zigbee buttons, bluetooth temperature sensor etc., that runs on a wide range of battery types. So you can check if the low battery warning is accurate before you change the battery.
