Review: Great battery tester for the money!! - This DLYFULL B4 battery tester is a must-have if you check a lot of rechargeable batteries or any other type of batteries. I also went over the tester and used white-out with a brush, and then wiped excess off using WD-40, sprayed on a napkin, and it took the residue off (because it was hard to see the # displayed on the unit), leaving it with white numbers that you can see clearly. This is the best battery tester that I have used so far. I found this tester easy to use, too. If you're looking for a good battery tester, look no further. I found this tester to be very accurate and worth the price.
Review: The best battery tester I've used! - I love this tester! It tests so many different types of batteries! The pulse testing gives a much more accurate reading of what what's actually left in the battery. It gives a percentage read out that is far more helpful than a needle gauge. A similar tester is 4-5 times more expensive and doesn't have the LCD readout. If you need a battery tester, buy this one!

### ⭐⭐⭐⭐ Good but not as easy to use as the B2 Tester from Dlyfull
*by B***J on September 28, 2025*

I had the B2 tester and it died after about 4 years of use. I liked it and decided to replace it with the B4 version. First, it's made well. Second, it's more accurate than the B2 version in that it shows percentage of charge. The B2 version only shows bars. I think both these testers are good value for the money. However, if you only really need to check AA, AAA, C, D and 9volt batteries, the B2 version is a lot easier to use because you don't have to use the probe tip on the B4 version. You just slip the battery in the right slot and you're done. However, I use a lot of different button batteries for various devices. The B4 accommodates them but sometimes you use the probe and sometimes you don't. It's a learning exercise. And testing the AA, AAA, C, D and 9v batteries in the B4 requires two hands. For the price I would buy both but don't have enough room on my work bench for both. I hope this helps others.
