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

Perfect for my usage as I use all rechargeable batteries in my home especially for flash photography….doesn’t require any battery or charging for the 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.

I volunteer for a non-profit replacing batteries in donated watches. I also use illuminated magnifiers and flashlights to see all those tiny parts (and *find them* when they *launch* themselves across the room. So, batteries of various sizes (D, 9V, AA, AAA plus perhaps fifty sizes of silver oxide, lithium, and alkaline "button batteries) are my daily concern. This seemed to fit my needs best. To use it, simply extend the orange terminal slide out wide enough to let you place the battery against the inside terminal, push the orange slide back in till it touches the other end of the battery and read the voltage and the device's opinion as to whether the battery is dead or on its last legs. This tester is compact, doesn't require a power source, adjusts to fit almost all battery sizes, and is accurate enough to let me know if a battery has enough charge to power the watch I'm working on. It fits into my tool kit, doesn't involve any cables and is more rugged than a traditional voltmeter. And it doesn't cost much. I can't speak to its longevity, but it seems durable enough for my needs.

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.

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

So far so good. The unit seems to be working well and giving accurate results at a reasonable cost. The good thing over other battery checkers is that it can also check 3 volt button batteries whereas others are limited to 1.5 volt when checking the button batteries.
