## Questions & Answers

A: I am not sure if I am correct but I would think it would not matter whether the batteries are lithium as long as they are AA or AAA.  It is a great battery tester otherwise.

**Q: why does it say ?  don't powered by rechargeable battery nor test rechargeable batteries**
A: I do not know why it says that but the batteries that I test are not rechargeable so have not had a problem.

**Q: Does the dlyfull universal battery tester
 test 2/3aa (650mah 1.2v) batteries?**
