Dlyfull Battery Tester, LCD Display Universal Battery Checker
The Dlyfull Battery Tester has proven to be an invaluable tool in my household. Its LCD display and universal compatibility with a wide range of battery types, including AA, AAA, C, D, 9V, and various button cells like CR2032, CR123A, and more, make it incredibly versatile and user-friendly. One of the standout features for me is the clear, easy-to-read LCD screen, which instantly displays the remaining power in the batteries, taking the guesswork out of determining their life. This has saved me both time and money by preventing the unnecessary disposal of batteries that still have life left in them. The inclusion of 1x AAA battery to power the tester itself is a thoughtful touch, ensuring that the device is ready to use right out of the box. Its compact size also means it’s easy to store in a drawer or toolbox, making it readily accessible whenever needed. Using the tester is straightforward and requires no technical knowledge, which I appreciate. It has helped me keep all my devices running smoothly by ensuring that I always know which batteries to recharge or replace. In summary, the Dlyfull Battery Tester is a practical, efficient, and reliable tool that I’ve found indispensable.

Works well easy to use
Seems to be working very well. I went through my pile of old batteries and discarded all the ones that were fair or less. I used it on a wide variety of size including the 2032 discs. It’s a nice little tool for my workbench.

Great tester for all my batteries.
Terrific device. Compact, versatile, easy to use. Paid for itself on day one. For example, rather than than discarding all four batteries on a nonfunctional device, I only threw away the one battery that was failing. … After getting mine, I bought two more to give as gifts to family members.

It has saved me money in batteries by verifying battery charge
Very helpful and works well. It's just a little awkward to put in the batteries but that is not a serious problem.

This is a useful tester as it does all the battery types I normally find around the house or office. Only downside is it takes a AAA battery to run. Bases on my experience of recent years, you will have to take the battery out should it sit unused for long periods of time, lest it leak and ruin the tester. I am trying Lithium batteries in items that have long standby times, as I understand they are not so prone to this failure.

I hesitated at first but I find the design and the digital readout very clear. Seems solid and durable.

Exactly what i had hoped for. Has already paid for itself by testing batteries that I thought were dead. Great investment
