La Crosse Technology 911-65557-INT Portable Digital Battery Tester

This is a very simple, versatile and effective tool for testing of batteries at home. Very easy to use and digital display bars really help to know the charge status very effectively. Great and must have tool for this digital age with 10s of batteries lying around at home for so many applications. Very reasonable priced for the quality of the product.

This inexpensive and small device is simple to use and tests a wide variety of batteries. I have used it several times now and it seems to provide quick and accurate enough results. It tests everything from button cells to nine volt as well as many common small batteries like AA & AAA.

Excellent produit. Belle qualité, très compact, facile d’utilisation, grande diversité de piles dont les piles rechargeables, lecture du voltage interne et de l’énergie résiduelle, pile interne non requise pour son fonctionnement. Vaut les quelques dollars de plus.

Muy práctico probador de baterías, sirve para todo tipo, muy recomendable.

This La Crosse battery tester is an excellent product. It works with a wide variety of voltages and chemistries. I have tried it on alkaline 1.5V (AA, AAA), USB lithium 1.5V (AA), NiMH (AA, AAA), and lithium coin cell 3V (CR2032, etc.) batteries and it appears to give timely and accurate measurements. I love that it is compact so it is easy to store and use on the go. There are a lot of battery testers on Amazon, most of which are Chinese knock offs/generics of a few designs. I appreciate that La Crosse has a unique design with a clear digital readout. You need to know what voltages mean for your particular battery chemistry (1.2V - 1.31V is considered "full" for NiMH batteries, for example), but I much prefer seeing the true voltage readout than generic terms like "good" or "empty". If you are wondering which of the forty different "caliper" or "zigzag" types of battery testers to get on Amazon, don't bother, just get this La Crosse 911-65557-INT one and be happy. The La Crosse 911-65557-INT battery tester is self-powered: powered by the battery that you are testing. There are two points to note about this design. First, if the battery you are testing is truly "dead" (below some critical threshold), nothing will display onscreen because there is no power in the first place. Second, since it is self-powered, the unit itself does not require its own battery so it will always "work" and will not get a corroded battery case because there is no battery case in the first place. If you really need to measure voltage down to the last 0.1V, this product is the wrong product for you. However, if you want to get accurate readings of batteries in various stages, this product is the best one in the price range.

Es una herramienta muy sencilla pero te ayuda mucho con todas tus baterias
