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!
Review: great gadget to have and well priced - great gadget and will save you money. I have lithium batteries in my cameras. Lithium batteries can last an unbelievable amount of time but you should always know the life of it. I almost replaced mine at 3years only to find out they were at 45%!! this will save you some money. Batteries are still going and its been 5 years lol

### ⭐⭐⭐⭐⭐ great gadget to have and well priced
*by A***R on September 8, 2026*

great gadget and will save you money. I have lithium batteries in my cameras. Lithium batteries can last an unbelievable amount of time but you should always know the life of it.

### ⭐⭐⭐⭐ It works, but requires double checking
*by F***C on June 20, 2024*

First, I purchased this unit. This is not a Vine review. The unit seems to work if you double check the batteries. When checking a battery, (even a brand new battery) most of the time its shows 95% capacity, not a 100%. If you then recheck the battery it will show 100%. I don't know what procedure they use to determine capacity, but I believe they are putting a load on the battery to check it. This is good because it gives a better reading. As an example, I checked a 23A battery with a multimeter and got reading of 11.56 volts. When I checked it with this checker it showed "ERR" and no capacity. The Dlyfull unit was right. The Multimeter has a high input resistance, and therefore did not load the battery. This tester loaded the battery and give a better reading. Why you have to check the battery twice is annoying, and I don't know if this is something in the unit design, or I have defective unit. This also happens with rechargeable batteries. It would nice if the unit would check AA, AAA Lithium batteries. This unit tests more accurately then the standard battery checker. This will tell you if the battery in your remote, or other product, is good and can supply the current your product needs. Would I recommend this unit? Yes. Even with the problems it better then a standard checker.
