Review: Had one. Had to buy another! - It arrived quickly. It's easy to use and works great! I already had one for the office and decided it was time to buy one of my workshop.
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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Had one. Had to buy another!
*by K***R on June 30, 2026*

It arrived quickly. It's easy to use and works great! I already had one for the office and decided it was time to buy one of my workshop.

### ⭐⭐⭐⭐⭐ Great battery tester for the money!!
*by G***. on July 8, 2026*

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.

### ⭐⭐⭐⭐ Easy to read digital screen, unusual testing method.
*by J***K on July 19, 2026*

Unusual battery tester. Place the positive end on the proper pin on the unit, then take the coiled lead and touch the negative end of the battery. Two handed job. Display will wake up, quickly test battery and give you a numerical percentage read out and a bar graph read out. It has been pretty accurate so far. The battery types are molded into the tester next to each pin, but could use some white filler material to make them stand out and easier to read. Unit uses an internal battery, 2 AAA. It can self-test it and remind you when to replace it. Four stars rating: hard to read markings for the battery types on the unit case, and the display shuts off just moments after you remove the battery you are checking.
