2 Pack Battery Tester, Universal Battery Checker for AA / AAA / C / D / 9V / 1.5V Button Cell Batteries

I had one of these for years. It was very convenient and easy to use to test the batteries I use the most. I also own a very expensive tester which tests a lot more kinds of batteries under loads. It requires its own internal batteries to operate. Because I use it infrequently I don’t keep batteries which could leak in it. So, it takes longer to load the batteries, use it, and unload the batteries. I had a few guests and my first one of these disappeared. Disappointed, I ordered this two pack. These are fast to use. They are a basic go/no-go test which is perfect most of the time. I have lost a lot of items which use these most popular batteries due to damage caused by battery leakage. Replacing them is expensive. Having this kind of tester allows me to quickly test. It’s easy to take a moment to check the batteries in multi battery devices to spot the battery going bad before it leaks. A lot of new batteries from top manufactures leak very early in life. One manufacturer replaced an eight pack of a new model AA battery in the month they were introduced. I opened the pack and one was already leaking. I tested the rest. Over half were failing. I sent them a video. They replaced them and because over half of them were bad I now never use that model. Testing batteries before they fail also saves me money by finding batteries that can still be used. It is a best practice to always replace all batteries at once in any multi-battery device. My kitchen sink faucet uses 6 AA. It starts to fail when a single battery goes bad. I replace them all. I keep the used batteries separate and I am able to reuse them in other devices. Having this kind of tester and reusing still good batteries has dramatically reduced my battery purchases. Because I ordered the two pack I was curious if the measured every battery the same. They do. I recommend these testers because they save a lot of money. They pay for themselves by avoiding damage to battery using devices and by allowing better battery use management to get the best use of every battery.

Battery tester has worked flawlessly Well worth the purchase price.Have tested a number of different battery types, with out a problem.The tester itself is simple to use and seems to be make of strong and durable materials.

work good and easy to use......... waiting to see how long they last. Price for 2 of them was great.

The is a great battery tester. It checks the battery life with great speed. Very durable. Check your batteries in your drawers. Also helpful when removing batteries from Christmas decorations. Check your batteries and save only the batteries that are still good. You can save one and put one in the garage or give one away

Not the best quality but honestly for the price it get the job one and you can see if the batteries you have are still holding a charge not to bad. But it is accurate which is important. It’s still reliable to this day. It’s a good over all battery tester.

1 works great, the other says all batteries are dead.

Works as advertised, easy to use, worth the money.

They work and price is good

El producto es bueno Y en precio calidad excelente

The product serves it's purpose. But only one piece delivered in the packet.

Funciona bien para conocer el estado de las baterías, aunque hay que manipularlas para que no se caigan cuando uno está probándolas.

Cumple con los requerimientos necesarios para verificar la carga de las baterías. 100% recomendable.

Entregaron DOS pero uno NO FUNCIONA, espero me manden un reemplazo.
