It can test about any type of battery.

### ⭐⭐⭐⭐ Nice meter, zero issues
*by S***E on March 7, 2023*

I got this meter for one big reason, and that was its ability to measure IR in 18650 cells. I didn't want to spend $100 for just that feature, saw this and bought. I've checked the voltmeter on it with 3 other meters I have. One is a $10 meter, another $65 and the last meter, $225. It is consistent and close. The only reason I didn't rate it a 5 was the (perhaps) lack of accuracy.measuring the resistance. A friend that had a 4 wire meter double checked mine and it was off. Doesn't really bother me as I just need a baseline number to compare good vs bad cells, as long as it's consistent, which it seems to be. All in all a good meter for the price, just not sure about the IR measurements.
